alpha beta prunning generics, writing an exception

Question

I have to implement the alpha beta prunning algorithm for the game 4Connect. I have to implement the method with generics:

public M getBestMove() throws GameException {

I don't really know what the statement "throws GameException" means. I tried to write my own exception. but I never did it before, so I could need some help from you

Do I need a try catch block in my method?

No, since your method throws an exception the client code, the code that calls this method, needs it in a try block.

try{
    Move m = getBestMove();
}catch(GameException e){
    //handle the exception
}

To answer your other question, you can do whatever you want after you catch the exception, so you can turn the game back on if you want.
