“Our world, moved by Java” - Take a moment to ponder over this expression.
One of the most widely used programming languages, Java is used as the server-side language for most back-end development projects, including those involving big data and Android development. Java is also commonly used for desktop computing, other mobile computing, games, and numerical computing. The popularity of Java is further evidenced with 90% of all Fortune 500 companies using Java.Download 20+ development projects [free]
4 reasons why software companies prefer Java for building enterprise applications
- The software industry embraced Java because it made development a pleasure, solved problems with distribution, and removed the pain of constantly porting across platforms.
- Since it is an object-oriented language; it’s robust and secure. Java programs are compiled independent of the platform in bytecode language which allows the same program to run on any machine that has a JVM installed. This is a natural and pragmatic approach to software design. Java objects encapsulate data and behavior so that code can be reused, which makes testing and troubleshooting easier.
- Java’s usefulness compounded when people realized how it could solve their problems on servers – bringing productivity, performance, and scalability to new levels.
- From internet distribution of software to server-side scaling of multi-tier architecture to taking advantage of constantly improving hardware architectures – to the cloud-native deployments, and a whole lot more, Java has established its supremacy over other languages.
“Time invested in learning the Java programming language is time well-spent.”
Companies will have a preference for applicants who have a passion for computer science. Showing that you have personal computer science projects is one of the best ways to show that you have a passion for the job, and are not just there for a paycheck.
Many developers have their own side projects, so don’t be left behind.

Java is widely used by game development companies and for creating mobile games. And this fact shouldn’t come as much of a surprise, given how versatile the language is and given its rich collection of open-source material.
Many of the world’s top mobile games have been developed in Java. Minecraft, Mission Impossible III, and Asphalt 6 are just a few popular names you are probably familiar with.
In Breakout Ball Game, a layer of bricks lines the top third of the screen and the goal is to destroy them all. A ball moves straight around the screen, bouncing off the top and two sides of the screen. When a brick is hit, the ball bounces back and the brick is destroyed. The player loses a turn when the ball touches the bottom of the screen; to prevent this from happening, the player has a horizontally movable paddle to bounce the ball upward, keeping it in play. The player uses the platform to keep the ball running. The goal is to break the bricks without missing the ball with your platform.Go to steps to build this game

Management systems are used in all institutions. It may be digital (software) or analog (record books/ledgers), but everybody surely uses it.
Today data is power.
But having said so this data should also be well-managed for clean and accurate data to exist at all times.
One such system is the Library Management System, which is used to keep a record of books present in a library. This system consists of information regarding Books, where we can perform all the operations that are required in an actual system such as CRUD operation, advanced search, book issuing, and also to store the information (in an encrypted format) within files using the process known as Serialization.Know more about the project
