Java projects list for beginners

Summary

Computers, since their inception, have taken over our lives, integrating itself with our every-day lives and activities. Similarly, with the growth of computing, came an influx of various new programming languages to help power that growth. One of the languages that stood out and gained popularity very quickly is Java. Java has grown to become a widely used language within the distributed internet environment. One of the biggest reasons for its ever-rising popularity is because it is considered the ideal platform to develop It is Android applications and Edge devices for the internet of things. Due to its universal appeal, young programming enthusiasts must have an understanding of Java and its principles to be effective programmers and App developers. If you are a newcomer to programming, you are at the right place, because here’s a look at some Java projects to help you get started on your journey.

Java Basics

Java came out as an alternative to C++ with the same look but is a simpler language to learn and use. It works on an object-oriented programming model and hence has more real-world applications than other languages. It can create both independent applications that run on a device and applications that are shared by servers connected in a network. Another important functionality of Java is the option to create small app modules for web-pages. Such versatility and flexibility have helped Java grow to become a leading programming language.

Why Java is popular?

1. High portability- Since the source code is compiled into bytecode, it can run on any network, server or machine that houses a Java virtual machine. The JVM is responsible for interpreting the bytecode and making it machine-ready. This is a different approach when compared to other languages such as C++, wherein code is converted into a binary file that is platform-specific.
2. Object-Oriented- An object contains related data files, attributes, and characteristics, and is a part of a class of objects which share the same code. This makes it easy to compartmentalize the program and split work between functions or methods, making programming easier, faster and more efficient.
3. Robust Code- Java programs do not make references to external data like C++ programs. Thus, there are no issues related to data being out of bounds due to inaccessible address locations. The JVM checks all calls for data to ensure the integrity of the code to prevent crashes and undue terminations.
4. Secure Data- Java does not use pointers the way C++ does and hence the data called by Java programs are safe. Also, since the source code gets converted into bytecode which we cannot read, it is safe from prying eyes. Furthermore, Java runs the programs inside a sandbox as a means to prevent external interaction and manipulation.
5. Flexibility- The apps are run on the client-server and not on the main server, making Java applets highly flexible. It also has several in-built features to make it faster and more efficient.
6. Easy to learn- Java is a great language for beginners because it is easy to learn and use, especially for people who have a background in C++.

JAVA projects list for beginners

Here’s a look at a few simple Java project ideas for beginners to help them get started on their journey. These beginner Java projects will help students understand the underlying concepts of Java and hence, prepare them for making more complex projects later on.

1. Unmanned Ground Vehicle

UGVs are a great way to start your Java coding if you are someone interested in the field of mechanical engineering, mechatronics or robotics. Such devices are the future of the manufacturing and production industry and are already being used extensively in production floors. Such vehicles help in automating various processes, by helping with transporting goods and loads from one part of the shop to the other. Java programs help power the navigation of such systems and are a great way to explore the field of both programming and robotics.

2. Optical Character Recognition using JAVA

We have officially stepped into the digital era, and hence so much written data that we see around us need to be converted into digital format. OCRs which have the capacity to read, and recognize written data through identifying each character helps us do exactly this. Hence, OCRs are the best way to process handwritten and printed data and feed this data into a system.

History of Java

The internet began to come out of the shadows and into mainstream use in 1996 and engineers from Sun Microsystems needed a platform to create small applications. They needed a platform to build apps that could effectively communicate with each other and work perfectly across devices connected in a network. Java was born out of this need and was, therefore, more inclusive of network programming than other languages due to the presence of java.net APIs. The full version came out in 1996, and a year later, the interface JavaBeans came out with releases being launched regularly as updates for the interface and the language. Fast forward to 2009, Google released the developer’s kit for Android software, and this included Java as a programming option for Android software. Oracle bought Sun in 2010 and took over the chain of command, and Java 8 came out in 2014 with the noted inclusion of Lambda expressions, helping developers write programs using a functional approach. The most recent version, i.e, Java 12 came out in March last year. The language has grown from strength to strength and as of 2016, over half the phones being used around the world, ran on Android, making Java one of the most widely used programming languages in the world!

What is the use of JAVA?

Java finds use everywhere from laptops, consoles, supercomputers, smartphones, and even the internet. Having a dedicated community of developers who constantly test, refine, extend and update the language has helped Java become a very refined and polished programming language with a large number of functions and features. Thanks to these Java architects and developers, over the course of two decades, the language has kept upgrading and evolving, bettering itself each time. Java has over the course of time, become invaluable to developers because it allows them to do the following:

1. Write the code on one platform and have it run on any platform of their choosing
2. Create applications that run within browsers and access other web services.
3. Develop server-side apps for poles and HTML forms processing
4. Combine services to create customized apps
5. Write powerful apps for various products such as phones, processors, sensors, microcontrollers, and the internet

All this has made it possible for 89% of computers in the US to run Java, and also have over 3 billion mobile phones use it.

How do you create a JAVA project?

Eclipse is a highly popular IDE for Java and is a great one for beginners to start with. It contains everything that you would need to build your very own Java project from scratch. Here’s a look at how to create a Java project on Eclipse.

1. Start off by installing Eclipse IDE on your computer. While installing, the system asks you for your choice of IDE. Make sure you go for Eclipse IDE for Java Developers, as this will make the program automatically install all the files required to create Java projects.
2. If you installed it for some other language, don’t worry, just add support for Java by installing new software from the Help menu.
3. Once the installation is complete, run Eclipse. Go to File>>New>>Java Project and this opens up a new window for you to start coding.
4. Start by giving your project a name. While naming, try to keep the title simple and relevant, so that when you visit it later, you know what the program does by just looking at the name.
5. Once you are done naming, choose a folder to store your files in because by default it saves it in the Eclipse directory.
6. Next, choose the Java Runtime Environment you want if you have a preference and if not the newest JRE is automatically chosen.
7. Now, choose a project layout which may be either a project folder or several separate folders for sources and class files.
8. Next, go to Next>>Java Settings to add additional libraries and make other changes related to the path and external features.
9. Use the Source button to define a path for the compiler, create source folders and create links to external sources. If you wish to add external libraries, do so using the Libraries tab.
10. Lastly, click on Finish to start working on your newly created project environment.
11. Hope you got some basic information about how to develop projects using JAVA and project topics from this article. If you have any queries or suggestions, let us know in the comments section.
