Choosing a Java Development Tool
If you're using a Microsoft Windows or Apple MacOS system, you probably have a Java interpreter installed that can run Java programs.
To develop Java programs, you need more than an interpreter. You also need a compiler and other tools that are used to create, run, and test programs.
The Java Development Kit includes a compiler, interpreter, debugger, file archiving program, and several other programs.
The kit is simpler than other development tools. It does not offer a graphical user interface, text editor, or other features that many programmers rely on.
To use the kit, you type commands at a text prompt. MS-DOS, Linux, and Unix users will be familiar with this prompt, which is also called a command line.
