  // this program works fine, BUT I want to know how to force the  // random number generator, ON LINE 14, to create a number within a certain limit, such as 0 to 10  // this program will create a random number and do a series of loops with the number you input  import java.util.Scanner;  class While2{  	public static void main(String[] args){ 	 		Scanner input = new Scanner(System.in); 	 		int random = (int)(Math.random() * 20); // if you dont put * SOMETHING then it will be default, 0 		 		// create while loop  		while(true){ 			System.out.println("Enter a number between 0 and 10: "); 			 			int number = input.nextInt(); 			 			if (random == number){ 				System.out.println("Your number matches the random number, " + random); 				break; // if u dont put this, it will keep asking you 				} 			else if (random > number) 				System.out.println("Sorry, but random ," + random + " is bigger than your number " + number); 			else  				System.out.println("Sorry, but your number is too high, compared to the random " + random); 		} 	 	} 	 }
