    Default Please help me solve this problem, this is really urgent!

    Hey, can you please help me out, every time i try to run this code I get an error:
    "Exception in thread "Thread-5" java.lang.StackOverflowError
    at players.K4LV1N.myMove(K4LV1N.java:115)
    at players.K4LV1N.move(K4LV1N.java:86)"

    Basically the move() method is called once every match by the SLArena and I am trying to store the moves in an array using the myMove() method.

    The code is:
    /**
    * Returns the next move in the sequence to SLArena.
    */
    public int move() {
    myMove ();
    if (++nextMove == LENGTH) {
    nextMove = 0;
    }
    if (moves[nextMove] == ROCK) {
    moves[nextMove] = PAPER;
    return PAPER;
    }
    if (moves[nextMove] == PAPER) {
    moves[nextMove] = SCISSORS;
    return SCISSORS;
    }
    if (moves[nextMove] == SCISSORS) {
    moves[nextMove + 1] = SPOCK;
    return SPOCK;
    }
    if (moves[nextMove] == SPOCK) {
    moves[nextMove] = LIZARD;
    return LIZARD;
    }
    moves[nextMove] = ROCK;
    return ROCK;
    }


    /**
    * Stores my previous move.
    */
    public void myMove () {
    myMove[nextMove - 1] = this.move();
    }

    Are the methods calling each other continually, recursively until the exception?
    You will have to change the logic so they don't do that.
    If you don't understand my answer, don't ignore it, ask a question.

    Hello KalvinL7!
    java.lang.StackOverflowError is usually caused by recursive calling with no end of recursion. In your code in move() method you call myMove() method and in myMove() you "call" move() (this.move()).
