Java (programming language)
From the Simple English Wikipedia, the free encyclopedia that anyone can change
- There is also the island Java.
Java is a programming language that can run on many different computers. It was originally developed by Sun Microsystems and released in 1995.
There are small programs, called Applets. They often run inside web browsers. Java should not to be confused with JavaScript. JavaScript is a scripting language with a similar syntax. JavaScript is mainly used by web browsers. Java can also run on Mobile phones.
[change] Background
Java is object oriented. Java code looks a lot like C++ or C code.
Java is platform independent, meaning it can run on many different operating systems. The way that Java manages this is making the Java compiler turn code into Java bytecode instead of machine code. This means that when you run a program, the Java virtual machine interprets the code into machine code during the program's running.
[change] Types of Java
There are many types of Java programs which run differently:
- Applet - can be put online (in web browsers).
- Application - can only be run on the computer, cannot be put online.
- Servlet - runs on a server and helps to display web pages.
- Swing application - like an application, but can have a more graphical look.
