Please tell me how to run a JFrame in eclipse,as when i put it in the Main class it runs but when i select some other frame in that same project that main class don't run....please tell me the buttons to run that specific main class every time when i run my project

You don't run "JFrames" in Eclipse or in Java. Instead you compile and run Java programs, and these can display JFrames if they are coded correctly. So based on this, the correct way to display a JFrame is to write code that does this. Have you gone through the Java Swing tutorials to learn how to create and display JFrames and other top-level windows?

In Eclipse select the "Run->Run configurations..." menu option. This will let you select the project and say which class will be regarded as the "Main class" for that project. Note that the class you make the Main class has to have a main() method!
