With most programming languages, computer programs are written by entering text into a text editor also called a source code editor. Some programming languages come with their own editor. NetBeans includes its own editor for writing Java programs. Java programs are simple text files without any special formatting, such as centered text or boldface text.
The NetBeans source code editor functions like a simple text editor with some extremely useful enhancements for programmers. Text turns different colors as you type to identify different elements of the language.
NetBeans also indents lines properly and provides helpful programming documentation inside the editor. Because Java programs are text files, you can open and edit them with any text editor.
You could write a Java program with NetBeans, open it in Windows Notepad and make changes, and open it again later in NetBeans without any problems.Small Toy Java Programs: You can keep many small programs (with main()) in one Java project instead of create a new project for each toy program.
To run the desired program, right-click on the source file ⇒ "Run as" ⇒ "Java Application". **JAVA PROGRAM** This project involves writing a program that implements an ATM machine.

This tutorial provides a step by step tutorial on writing your first hadoop mapreduce program in java. This tutorial uses gradle build system for the mapreduce java project. Java has been generating a lot of excitment because of its unique ability to run the same program on IBM, Mac, and Unix computers.
Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.
