Question

Program Description: Write a program to create an array based on a * size specified by the user. After creating the array, the * program will create a random number that represents how many * numbers to insert into the array. A 'for' loop will be used to * insert that many numbers into the array. The numbers inserted * into the array will be random numbers between 10 - 20. *BEGIN Array Input Using Sentinel Value * Prompt User for size of the array * Instantiate the array * Create a random # (0 - array size) for how many #s to insert * FOR (each number to be inserted into the array) * Create a random number between 10 - 20 * Insert the number into the array * ENDFOR * Clear the Screen * FOR (Each value in the array) * Display value on its own line * END FOR * END Lab01 - Array Input Using Sentinel Value

Explanation / Answer

import java.util.Random;

import java.util.Scanner;

public class RandomNumber {

   public static void main(String[] args) {

       Scanner sc = new Scanner(System.in);

       Random r = new Random();

       System.out.print("Enter size: ");

       int len = sc.nextInt();

      

       int[] arr = new int[len];

      

       for (int i = 0; i < arr.length; i++) {

           arr[i] = r.nextInt(11) + 10;

       }

      

       System.out.println("Array: ");

       for (int i = 0; i < arr.length; i++) {

           System.out.print(arr[i]+", ");

       }

   }

}
