Answer 1

For example, let's say that you want to create a random number between 50 and 60, you can use one of the following methods.

new Random().nextInt()%6 +55

new Random().nextInt()%6 returns a value between -5 and 5. and when you add it to 55 you can get values between 50 and 60

Second method:

Math.abs(new Random().nextInt()%11) +50

Math.abs(new Random().nextInt()%11) creates a value between 0 and 10. Later you can add 50 which in the will give you a value between 50 and 60
