How do I randomly generate a number between 75 - 100%?

I know how to do it between 0 and 100, but I can I set the floor?

This is how I do 0 - 100..

int randomNum = (int) Math.ceil(Math.random(开发者_开发知识库) * 100);

Generate a random number from 0 to 25 and add 75. :)

int randomNum = (int) Math.ceil(Math.random() * 25) + 75;

Generate a number between 0 and 25 and then add 75.

I know this is answered already but correct answer did not have code snippet. So here is a little code snippet:

int randomNum = 0;
Random ran = new Random();
randomNum  = ran.nextInt(25) + 75;
