    Can you please format your code and use the code tags?

    I notice a few mismatched curly brackets, but that might be because you aren't using them on a single-line if statement. Hard to tell without seeing formatted code.

    What line is the error on?

    Also, what is this line supposed to do:

    int randomIndex = int computer;

    I take it that 'computer' is suppose to represent the computer competition and therefore should be set to the random that you call 'x'.
    you create the random which is to choose whether the computer has rock, paper or scissors but the random is never used.
    To make it work you need to replace the line:
    int randomIndex = int computer;
    int computer = x;
    Also the concept of the code will not work as paper is lager than scissors but scissors is suppose to win over paper.

    i would look into this tutorial: How to Make a Rock, Paper, Scissors Game in Java (with Pictures)

    this tutorial shows how to implement methods to seperate different actions.
