Before I can write a Java program

Hi Experts,

I knew little Java a few years ago and forgot all of them now.
However, I need to write a (very simple) Java program at the moment!
Can you suggest any software for editing, compiling and running Java codes? Where to download and how to install for my WindowsXP?

Thank you in advance.

OK, I installed J2SE v 1.4.2_06 SDK. Do I need to set something before I run my code?

sudhakar_koundinya

I don't know which IDE you are preferring.

If you have installed Eclipse/Net Beans IDE. You don't need any further software

OK,

If youd did not installed Eclipse like IDE then write a program in Notepad

and you need to compile them at command prmpt.

Thanks a lot!
I have done the 'set path' and 'set classpath', I found MyClass.class after javac, but when do java, I got
Exception in thread "main" Java.lang.NoClassDefFoundError: c:\...MyClass

MyClass.java is my program, do you think I did something wrong in it?
