Several ways ...a) Runtime.exec("java -classpath c:/ sample"); // :Pb) Make sure C:\ is in the CLASSPATH, then call sample.main(new String[] {}); from within your (other) class.

the reason you're not getting a straightforward answer is that this is the sort of thing you can find out for yourself in the tutorials, or from your teacher, or a book, or a simple google query. the forum isn't the place for complete novices to learn from, that would be a waste of effort on everybody's part

get reading!

... or because it's hard to understand why you'd want to do what you asked for.

you've never had to invoke methods in one class, from another class?

presumably all your logic is inside one Main method, and doesn't involve any objects at all then :)

well, in all fairness, the OP never asked that. Rene merely suggested it

Sure. OOP is for girls ...

That's why I dared to ask the OP, see reply #5. It's highly probable the OP wants to do something similar.
