This instructable is for staging your computer to be able to write your own code compile and run java without using the NetBeans program and its all free software.Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform . The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file ) that can run on any Java Virtual Machine (JVM) regardless of computer architecture . Thanks Wiki
(Only Windows) You will need to install, "Java SDK"(Java source code) and "Crimson Editor"(Color Text Editor). Links below.
Download the latest release of the Java SDK or JDK (means the same thing) from http://java.sun.com. You will get an install program named something like j2sdk-1_4_1_05-windows-i586.exe, run this program and it will install the Java Software Developers kit. (make sure the file is called j2sdk####, and not j2jre#### which is the Java Runtime Environment).
Download the latest release of crimson editor from http://www.crimsoneditor.com. You will get an install program named something like cedt.exe, run this program and it will install crimson editor on your system.
