Using the Sun Java Development Kit.

Download the JDK from www.javasoft.com (Warning: it’s over 20MB!)

Suppose you’ve installed it in c:\jdk1.2.1

Create an application development folder:

c:\myjava\hwo1

In this folder create a file COMPILE.BAT

c:\jdk1.2.1\bin\javac Myprog.java

Also in this folder create a file RUN.BAT

set classpath=.;c:\jdk1.2.1\lib;c:\myjava\hwo1;

c:\jdk1.2.1\bin\java Myprog

This assumes your main class Myprog has a static main method.
