Comparing Answers (Not in Array)

How do you tell Java to print the value of matching numbers that are randomly generated. For example, if the output is 3,3,7: the system should print out, "You got two 3's".

    int roll1 = (int) (Math.random()*6) +1;
    int roll2 = (int) (Math.random()*6) +1;
    int roll3 = (int) (Math.random()*6) +1;


    System.out.print("Your numbers are " + roll1 + r2 + r3);

    if (r1 == r2 && r2 ==s3 )
        System.out.print(": You got all" + s1 + "'s");
    else if (r1 == r2 || r2 == r3 || r1 == r3)
        System.out.print(": You got two" + "'s");
    else if (r1 != r2 && sr != r3)
        System.out.print(": NO MATCHES!");
    else {

    }
