Can i limit how many times the same random integer is chosen?

Hi, I'm wondering if there is a way I can control how many times the same random integer is produced. For example, if I'm trying to produce numbers between 1-5, and I want to limit the amount of times that 5 can be chosen, to two. So, basically customize the amount of times each number is allowed to show up when producing them. Thanks to anyone that can answer me.

Just keep a count using an if statement.

int choosen5 = 0;

int nextNumber;
boolean getDifferentNumber;

do {
    getDifferentNumber = false;
    nextNumber = random.nextInt(5) + 1;
    if(nextNumber == 5) {
        choosen5++;
    }
    if(choosen5 > 3) {
        getDifferentNumber = true;
    }
while(getDifferentNumber);
