Explanation / Answer

Dear, Here is the code.. //*********************************************************// LuckyNumbers.java // To generate three random "lucky" numbers //********************************************************* import java.util.Random; public class LuckyNumbers { public static void main (String [] args) { Random generator = new Random(); int lucky1, lucky2, lucky3; //Generate lucky1 (a random integer between 50 and //79) using the nextInt method (with no parameter) lucky1 = Math.abs(generator.nextInt()) % 30 + 50; //Generate lucky2 (a random integer between 90 and //100) using the nextInt method with an //integer parameter lucky2 =generator.nextInt(10)+90; //Generate lucky3 (a random integer between //11 and 30) using nextFloat lucky3 = (int)(generator.nextFloat() * 19 + 11); System.out.println("Your lucky numbers are " + lucky1 + ", " + lucky2 + " ,and " + lucky3); } } Output: Your lucky numbers are 61, 95, and 17 Hope this will help you..
