Java: .class expected?

Im working on a TTT game, and im trying to make the AI capable of sellecting from an array of multiple moves. My code:

public int multipleMoves(int[] board, int[] possibleMoves) {
        if (possibleMoves.length != 0) {
            return int whyIsThisNotWorking = new Random().nextInt(possibleMoves.length);
        }
    }

Tho this code cant compile, and it stops with the error message: java: .class expected.. This it says the error is occuring on the variable itself, but i dont get this. Thanks in advance!

Don't declare a variable in the return statement. Java already knows you want to return an int from the method signature. Just return the value directly. Don't forget you must always have a return value (or failing that, throw an exception). Right now nothing happens when the condition in your if statement is false. The compiler is going to complain about that too. For example:

    public int multipleMoves(int[] board, int[] possibleMoves) {
        if (possibleMoves.length != 0) {
            return new Random().nextInt(possibleMoves.length);
        }
        return 0;
    }
