    find what code im wrong
    Please explain why you think there is something wrong with the code.
    If there are error messages, copy the full text and paste it here.
    If the output is wrong, copy the full text and paste it here with comments saying what is wrong.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    two problems i can see, rnum is an instance of class Random, it is not a method that returns an int that you can assign to int variable jackpot. Also in your loop when you generate each random number you need to save it to a variable before you can print and test it.
    int jackpot;
     
    for (counter = 1; counter <= 5; counter++) {
        jackpot = rnum.nextInt(200);
        System.out.println(jackpot);
        /* This println statement will only execute,
         * if the above condition is true
         */
        if( jackpot = 100){
            System.out.println("jackpot!");
        }
    }

    @tonya - Did you compile and execute the posted code? Did it work?
