What Is Java?

Chances are you’ve visited a website or downloaded a program that insisted you download something called Java before it would work. This can be a pain, especially if you have no idea what Java actually is.

According to Lifehacker, “Java is a programming language that developers use to create applications on your computer.” With the web plug-in, you can run different apps in your browser.

One important thing to remember about Java is that it is not the same thing as Javascript. The two have very little in common. Javascript runs primarily in your browser because it is generally used in HTML documents. Java, on the other hand, is used to run standalone web apps.

 

Java has two parts

    1. Java Runtime Environment (JRE)

The Java Runtime Environment is what comes when you download the Java software. It consists of different parts, including the Java Virtual Machine, computing platform core classes and supporting Java platform libraries. The runtime lets you run Java apps on your computer.

    1. Java browser plug-in

This is how your browser connects with the Java computing platform. This allows applets on different websites to run within the browser. It is included when you download the Java software – it is part of the current version of the JRE.

 

Benefits of Java

Java is one of the most widely used programming languages available today. That’s because it incorporates these key features:

  • Usability – Java is easy to use because it stems from and improves upon the programming language called C++. The syntax of C++ is often considered too complicated; Java built on the language and made it easier to use.
  • Reliability – Java uses “object-oriented programming.” This allows Java to focus on data and represent it piece by piece.
  • Independence – Java works across different platforms. It is a portable language “that doesn’t care about the operating system or the hardware of the computer.”
