Random value from enum with probability

Question

I have an enum that I would like to randomly select a value from, but not truly random. I would like some of the values to be less likely of being selected so far. Here is

Answer 1

You can create an enum with associated data bby provding a custom constructor, and use the constructor to assign weightings for the probabilities and then

public enum WeightedEnum {
    ONE(1), TWO(2), THREE(3);
    private WeightedEnum(int weight) {
        this.weight = weight;
    }
    public int getWeight() {
        return this.weight;
    }
    private final int weight;

    public static WeightedEnum randomType()  {
        // select one based on random value and relative weight
    }
}
