Random boolean with weight or bias

Question

I need to generate some random booleans. However I need to be able to specify the probability of returning true. As a results doing:

private R

Expanding on user2495765's answer, you can make a function which takes an input ratio (as two values chance:range see code)

public class MyRandomFuncs {
    public Random rand = new Random();

    boolean getBooleanAsRatio(int chance, int range) {
        int c = rand.nextInt(range + 1);
        return c > chance;
    }

}

Depending on what you intend to do, you probably don't want to initalize Random from within your method but rather use as a class variable (as in the code above) and call nextInt() from within your function.
