What Is Java Programming Used For?

Java is a powerful, portable object oriented (OO) programming language. It's used on Web pages, in cell phones and on mainframes all around the world. A program written in Java on a PC can easily find its way into many different computing platforms. This makes Java a popular language for application development.

  1. History

    • Java was invented in 1991 by a team of software engineers at Sun Microsystems led by James Gosling. His team saw the future of computing as an interaction between consumer devices and computers.

    Applets

    • Java programming is commonly used for Web-based applets. These are small applications such as pop up calendars.

    POS

    • Java programming is also used for point-of-sale (POS) applications. A separate library called JavaPOS was created to support electronic cash registers and their peripherals.

    Games

    • Java's graphic library makes it a great choice for simple games. These games are run on everything from Web pages to your cell phone.

    Multi-Threading

    • Java programs can do several actions at the same time, called multi-threading. A well-written Java program can process data in one thread while waiting for user input in another thread.

    Fun Fact

    • When Java is done using variables, it removes all references to them in memory with a process call Garbage Collection.
