This is the easiest way to generate a random number (in a given range) in Java. This can be helpful especially if you want to randomize an animation in Android. It might be useful in Java too (if you need a random number out of a range).
int min = 65;
int max = 80;
Random r = new Random();
int i1 = r.nextInt(max - min + 1) + min;
Hope this little snippet helps!
