What is difference between debug,deploy,build and run in java?

Hey dhk123,

when running a program it is simply executed by someone (like you're running your browsing while reading this).
Debugging is a special kind of running a program - you can set break points, jump into certain code sections, check and modify variables and follow the flow of your code.
Building means that you prepare software for deployment. For example: You build all your source code to a jar or war file.
Deployment is the process of taking a built file and copy it on a server, for instance, so that others can run it. For example: You deploy an application on a Glassfish server.

Hope that was clear enough. If not, I can go into fufther details.

Best regards,
Andy
