how to restart a java program??

can anyone tell me if there is a command to restart a java program from the main method again. Basically at the end of the program it asks for user input. if they type in Y or N, Y restarts, whereas N will quit. I'm new to this and any help will be appreciated.

Same way as you would call any other method.

Can you call main? I had a vague feeling that you couldn't. (If you can, it'll just be a case of typing main() if you're not supplying any arguments to it via the command line).

Personally I'd just do it by having the whole program running in a while(true) loop, and if the user types N at the prompt, calling System.exit(0), and doing nothing if they type Y, and letting the loop start again at the top.

yea this is the normal way of doing it. when ever the exit method is called (or directly change var) runs the current loop then finishes
