Question

I am working on a game. I want to do something like 50% of the time it shows you are lucky today here is $100 and 50% of the time it should say better luck next time. Can anyone please guide me how can i do this? I am using eclipse and java.
I have this so far:

for (int a = 0; a < 100; a++) {
            int per = 0;
            per = GenerateRandom.getRandom(2);
                        if (per<50)
                        {"better luck next time"}
                        else
                        {"you won $100"}
}

Is this right way to do? Or is there better way to do it?

First – no, that’s not quite the way to do it. You would want to make use of the Random class in Android to generate pseudo-random numbers. (You can learn more about PRNGs here.)

In my mind, the best way to do this (from a practical Java standpoint is to use code similar to the following:

public String isLucky() {
    Random ran = new Random() * 100; // Generates values between 0 and 100 exclusive
    return ran <= 49 ? "Better luck next time!" : "You win $100!"
