Hi dude, its very easy and not needed to have much more help. You can do it simply by going to your directory where your java has been installed.Then copy your path of the bin directory and the go to the properties of my computer and select advanced tabbed pane. Click on Environment Variables and in user variables part type "new" and provide variable name as Path which you have copied now. Simply open your computers command prompt and type
javac <filename.java>
This will compile you program. Then to run simply type
java <filename>

It is a simple thing. You want to run a simple java program and also you have installed jdk 1.3 . First go to the bin directory of the jdk. Then simply type javac filename.java for compiling it and then run it by typing java filename. This will executes your java program. It will give you output. You can use any book for getting more knowledge. Which book you are currently using? Check that book also, I think in that also you will get these steps.

Hi, First save that file with .java extension. Then to compile that program just open your command prompt. type

"cd\"

and press enter. Then simply type

"path=<path of bin directory of jdk 1.3>"

and press enter. Then go to the the path of your program and go into that directory. Then type

"javac <filename.java>"

and press enter. Then again type

"java <filename>"

to run you program. Here basically your javac will check whether there is any error in your program code or not. If you have error in program then it will show that error. If you find error simply solve it and then try to run that code.
