Java code Compilation Programatically

Hi,
I'm using JDK1.2.2.In my application,when I selct a program name from a listbox(say,Add.java) and click the Ok button,it should compile the Add.java file and Add.class file should be created.How to compile a java file within another java application.Can anyone help me out.
Thanks in advance.
