Question

Array Basics pls help

Answer 1

Answer:

import java.util.Random;

class Main {

 static int[] createRandomArray(int nrElements) {

   Random rd = new Random();

   int[] arr = new int[nrElements];

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

     arr[i] = rd.nextInt(1000);

   }

   return arr;

 }

 static void printArray(int[] arr) {

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

     System.out.println(arr[i]);

   }

 }

 public static void main(String[] args) {

   int[] arr = createRandomArray(5);

   printArray(arr);

 }

}

Explanation:

I've separated the array creation and print loop into separate class methods. They are marked as static, so you don't have to instantiate an object of this class type.
