This project aims to smoothen the supply chain management process by closely monitoring the dealers and clients and continually tracking the products through the different points in the supply chain. Using this application, a company can directly communicate with its clients, obtain the product requirements, manufacture the product to fit those requirements, and finally ship it off to the client. 

This project uses JSP, JDBC, and HTML for the front-end and MS Access as the back-end database. It is a web-based application that will automate the system of communication between the management or admin, dealers, and clients of the company. There are three modules in this application:

• Admin module – The Admin uses this module to check information on the manufactured products, newly launched products, and products that must be delivered to the clients.
•  Dealer module – This module keeps track of all the essential information concerning the dealers, particularly the record of items. Dealers can generate and update the item list for a product using this module. 
• Client module – The client uses this module to provide the necessary specifications of a product. The client feedback is processed through this module and forwarded to the Admin. 

By using this application, the clients can directly convey their product requirements to the manufacturer, who then contacts multiple vendors to acquire the necessary resources for making the product. The dealers usually create a list of items as per the product information provided to them, after which the manufacturer selects the materials that best fit the specifications given by the client.

Then, the selected list of items is forwarded to the inventory department for processing, after which the manufacturing begins. Once the production is complete, the accounts department calculates the raw materials costs and manufacturing costs to generate the total bill. Finally, the product, along with the invoice, is shipped to the client. The client is free to offer feedback on the received product.

20. Virtual private network

VPN is one of the trending java projects. The goal of building this virtual private network (VPN) is to extend a private network across a public domain (for example, the Internet).

There are three interconnected modules in this VPN project: 

• Administration module – This module monitors all the office operations and manages the staff details. 
• Marketing module – This module handles everything related to the marketing operations of the software application.
• Training module – This module manages all the technical operations like software testing, networking, call center, and J2EE training.

Confidentiality, authentication, and data integrity are the three core elements of this VPN security model. The other pivotal features of this application are:

• It allows for the addition of new clients, a feature better known as “scalability.” This feature allows a company/organization to accommodate new clients in the network as it expands. 
• It uses a remote backup server to prevent the system from failing due to sudden crashes. Since a VPN handles a large volume of files that are created every day, it is crucial to have a remote backup server to process all the requests coming from the client to the server and vice-versa.
• It uses a remote monitoring system to keep track of the activities of every client or individual connected to the VPN. This ensures that the privacy and security of the network remain intact.
• As is true of all VPNs, this VPN application, too, has the provision for certification in the system. When two or more LAN (Local Area Network) systems interact, certification is mandatory to protect the system’s security. 
• It triggers and sends acknowledgment signals to notify clients of successful data transfer (whether or not the data has successfully reached the desired destination).

22. Mobile tracking system

Of all the Java project topics , this one ranks among the top useful application ideas. Mobile phones are no longer used for luxury but have become a necessity in the modern world. With violent incidents becoming commonplace, safety concerns have increased manifold in the last couple of years. This is where Java mini projects like this come in handy. 

As the name suggests, the mobile tracking system tracks the present location of a user’s phone. This web application is developed on MySQL database using PHP. It constantly updates the location of the chosen device every five seconds through a central tower. The system sends the server the mobile ID and location, along with the time the device was present at the location.

The system has to be installed in the chosen device, following which each device is assigned a unique ID. This ensures you can track the desired mobile phone from anywhere, anytime. This project aims to boost security and consists of two primary components: the web application (serves as the admin) and mobile tracking software installed on the phone to be tracked. 

Although Java is a relatively new programming language ( it was launched in the early 1990s ), it has created a unique niche in the IT industry. Java is the driving force behind some of the largest organizations, including Airbnb, Uber, eBay, Pinterest, Groupon, Spotify, Intel, Symantec, TCS, Infosys, Wipro, Flipkart, and TripAdvisor, to name a few.

As an OOP language, Java has a modular structure, making solving complex problems significantly easier. Thus, programmers can write reusable codes with Java, enhancing the development process. Additionally, Java offers various features, such as polymorphism, abstraction, inheritance, and encapsulation, that further simplify the code-writing process. Easy to program and run, Java-based applications can be developed to operate on one computer as well as multiple client and server systems within a network.

The five main reasons for Java’s popularity are:

• Platform independence – Java runs on the WORA (Writing Once, Run Anywhere). A Java code is compiled into an intermediate format (a.k.a. bytecode), which is then executed in the JVM (Java Virtual Machine). So, any system running a JVM can execute Java code. Furthermore, JRE (Java Runtime Environment) is compatible with all three operating systems – Linux, macOS, and Windows.
• Multi-threaded – Java has inbuilt multithreading capabilities, which means that you can develop highly interactive and responsive apps with multiple concurrent threads of activity using Java.
• Object-oriented – Java is a purely object-oriented language. Inspired by C and C++, Java extends the functionality of these languages to become a pure object-oriented programming language. Abstraction, encapsulation, inheritance, and polymorphism are some of its core OOP features. 
• Secure – When it comes to safety, Java incorporates a host of safety features into the runtime systems, including runtime checking and static type-checking at the time of compilation. With these features in place, it is pretty challenging to hack into a Java application from an external source.
• Robust – Java leverages a simple memory management model reinforced by automatic garbage collection. Since Java objects do not require external references, Java code is robust. Besides, it also encourages developers to adopt productive programming habits for developing secure and reliable applications. The more you experiment with different java projects, the more knowledge you gain.
• Open source – Java’s position as the second most trending programming language worldwide ( IEEE Spectrum ) in 2023 primarily rests on it being freely available for use; in other words, it is open source. This makes it ideal for developers and programmers of various competencies looking to build apps of their own. They can even access the latest versions of Oracle JDK and Open JDK free of charge through the Java Development Kit.
• API rich – Consisting of approximately 52 keywords, Java boasts a rich and extensive API (Application Programming Interface). Thus, making projects in Java is easy, with a multitude of methods available for use in any program directly. Developers can accomplish any task with Java API methods, whether handling output input, networking, processing XML, or connecting to databases.
• Community backup – Java’s robust and active community is among the many reasons for its continuing popularity. The Java Community, Stack Overflow, and Java in General are some of the top communities where developers and beginners alike can find assistance when faced with a problem. If you are developing core Java projects or seeking project ideas for Java, you can find extensive and reliable support on these websites from expert developers.
• Documentation support – Another factor contributing to Java’s immense popularity is its detailed documentation feature. Javadoc, a well-documented guide, provides solutions to developers who face problems while coding any application or program.
• Development tools – In addition to frameworks, integrated development environments (IDE), and profilers, Java has an arsenal of various automation, debugging, and editing tools. Java has tools for every type of development project along with various stages of development. Different projects in Java require the use of different tools. These include Maven for building applications, Jenkins for integration and delivery, JIRA for bug tracking and planning, and Splunk for monitoring, to name a few.
• User-friendly – Java offers an easy learning curve with its simple English syntax and use of minimum special characters. This makes it easy for beginners and professionals to master this language. Basic knowledge of programming languages like C and C++ is all that is needed to learn Java and build projects using Java later. Resources are readily available online on various websites, mostly for free.

In the software industry, presentations play a major role as information can be conveyed easily in a presentable way via presentations. Using Java, with the help of Apache POI, we can create elegant presentations. Let us see in this article how to do that.

Necessary dependencies for using Apache POI:

It has support for both .ppt and .pptx files. i.e. via 

• HSLF implementation is used for the Powerpoint 97(-2007) file format 
• XSLF implementation for the PowerPoint 2007 OOXML file format.

There is no common interface available for both implementations. Hence for 

• .pptx formats, XMLSlideShow, XSLFSlide, and XSLFTextShape classes need to be used.
• .ppt formats, HSLFSlideShow, HSLFSlide, and HSLFTextParagraph classes need to be used.

Let us see the example of creating with .pptx format

Creation of a new presentation:

Next is adding a slide

Now, we can retrieve the XSLFSlideLayout and it has to be used while creating the new slide

Let us cover the whole concept by going through a sample maven project.

Example Maven Project

Project Structure:

As this is the maven project, let us see the necessary dependencies via pom.xml

PowerPointHelper.java

In this file below operations are seen

• A new presentation is created
• New slides are added
• save the presentation as

We can write Text, create hyperlinks, and add images. And also the creation of a list, and table are all possible. In general, we can create a full-fledged presentation easily as well can alter the presentation by adjusting the slides, deleting the slides, etc. Below code is self-explanatory and also added comments to get an understanding of it also.

We can able to get the presentation got created according to the code written and its contents are shown in the image below

We can test the same by means of the below test file as well

PowerPointIntegrationTest.java

Output of JUnit:

We have seen the ways of creating of presentation, adding text, images, lists, etc to the presentation as well as altering the presentation as well. Apache POI API is a very useful and essential API that has to be used in software industries for working with the presentation.

How to Choose a Great Presentation Topic in 5 Steps

120 presentation topic ideas, 5 presentation tips.

4. Choose an appropriate presentation style.

There are many ways to present a topic. Your personality, the topic at hand, and your audience’s personas will help you determine which style would best fit you and your audience.

Select a presentation style that will communicate the main idea clearly and have a lasting impact on your audience.

For instance, explore a freeform style presenter by Sir Ken Robinson.

5. Engage with your audience.

Work on your presentation skills to make a strong connection with your audience, get through to them and leave a mark.

Think of the presenter as the link between the topic and the audience. A strong or a weak presenter can make a difference between a presentation being a thriving success or a boring failure.

Hone your skills by engaging and interacting with your audience. Make them feel like a part of the presentation and not just spectators. 70% of marketers have found presentations with interactive content to be more effective than those without.

Here are a few ways you can make your presentation interactive:

• Start your speech with uncommon questions to your audience. Involve them from the get-go, like ask to raise their hands if X.
• Make eye contact to build credibility and show confidence. Don’t stare at your slides or notes. Smile occasionally and talk to the audience directly.
• Have an active and confident body language. Don’t stand in the same place the entire time. Move around the stage.
• Don’t be monotonous. Speak as you would to a colleague — with enthusiasm.
• Ask close-ended questions in between to keep the audience engaged without losing time. Address them using their names to keep things interesting.
• Share personal experiences and stories that your audience will find fascinating and relatable.
• Practice thoroughly before you present so you’re fluent with the material and delivery.
• Energy and excitement can be quite contagious. Make sure you exude enough to spread some to your audience.

Feeling Inspired Yet?

Now you have all the right ingredients for choosing amazing topics and a hundred ideas to drive inspiration from. So, go ahead and start cooking presentations that will blow your audience away.

Don’t forget to choose a super-relevant topic and add meaty information. Do it with excitement to make it enjoyable for you and your audience. Best of luck!

What is Memorial Day? The true meaning of why we celebrate the federal holiday

For many Americans, Memorial Day is more than a long weekend and an unofficial start to the summer season. The real meaning of the holiday is meant to honor all U.S. soldiers who have died serving their country.

Originally called Decoration Day, Memorial Day's history goes back to the Civil War. It was was declared a national holiday by Congress in 1971, according to the U.S. Department of Veterans' Affairs.

Although Veterans Day in November also honors military service members, Memorial Day differs by honoring all military members who have died while serving in U.S. forces in any current or previous wars.

The late-May holiday has also evolved into an opportunity for Americans to head to the beach or lake , travel to see friends and family , or even catch a Memorial Day parade .

Here's what to know about the history and the reason behind why we observe Memorial Day.

When is Memorial Day?

One of 11 federal holidays recognized in the U.S., Memorial Day is always observed on the last Monday of May. This year, the holiday falls on Monday, May 27.

Why do we celebrate Memorial Day?  

The origins of the holiday can be traced back to local observances for soldiers with neglected gravesites during the Civil War.

The first observance of what would become Memorial Day, some historians think, took place in Charleston, South Carolina at the site of a horse racing track that Confederates had turned into a prison holding Union prisoners. Blacks in the city organized a burial of deceased Union prisoners and built a fence around the site, Yale historian David Blight wrote in  The New York Times  in 2011.

Then on May 1, 1865, they held an event there including a parade – Blacks who fought in the Civil War participated – spiritual readings and songs, and picnicking. A commemorative marker was erected there in 2010.

One of the first Decoration Days was held in Columbus, Mississippi, on April 25, 1866 by women who decorated graves of Confederate soldiers who perished in the battle at Shiloh with flowers. On May 5, 1868, three years after the end of the Civil War, the tradition of placing flowers on veterans’ graves was continued by the establishment of Decoration Day by an organization of Union veterans, the Grand Army of the Republic. 

General Ulysses S. Grant presided over the first large observance, a crowd of about 5,000 people, at Arlington National Cemetery in Virginia on May 30, 1873.

This tradition continues to thrive in cemeteries of all sizes across the country. 

Until World War I, Civil War soldiers were solely honored on this holiday. Now, all Americans who’ve served are observed. 

At least 25 places in the North and the South claim to be the birthplace of Memorial Day. Some states that claim ownership of the origins include Illinois, Georgia, Virginia, and Pennsylvania, according to Veterans Affairs.

Despite conflicting claims, the U.S. Congress and President Lyndon Johnson declared Waterloo, New York, as the “birthplace” of Memorial Day on May 30, 1966, after Governor Nelson Rockefeller's declaration that same year. The New York community formally honored local veterans May 5, 1866 by closing businesses and lowering flags at half-staff. 

Why is Memorial Day in May? 

The day that we celebrate Memorial Day is believed to be influenced by Illinois U.S. Representative John A. Logan, who was elected to the U.S. House of Representatives as a Democrat in November 1858, and served as an officer during the Mexican War.

It is said that Logan, a staunch defender of the Union, believed Memorial Day should occur when flowers are in full bloom across the country, according to the  National Museum of the U.S. Army.

Congress passed an act making May 30 a holiday in the District of Columbia in 1888,  according to the U.S. Congressional Research Service.

In 2000, the National Moment of Remembrance Act – which created the White House Commission on the National Moment of Remembrance and encourages all to pause at 3 p.m. local time on Memorial Day for a minute of silence – was signed into law by Congress and the President.

What is the difference between Memorial Day and Veterans Day?

Memorial Day and Veterans Day both honor the sacrifices made by U.S. veterans, but the holidays serve different purposes.

Veterans Day, originally called “Armistice Day,” is a younger holiday established in 1926 as a way to commemorate all those who had served in the U.S. armed forces during World War I.

Memorial Day honors all those who have died.
