Live Demo
package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {
   public static void main(String[] args) {

      // initializing unsorted int array
      int iArr[] = {2, 1, 9, 6, 4};

      // let us print all the elements available in list
      for (int number : iArr) {
         System.out.println("Number = " + number);
      }

      // sorting array
      Arrays.sort(iArr);

      // let us print all the elements available in list
      System.out.println("The sorted int array is:");
      for (int number : iArr) {
         System.out.println("Number = " + number);
      }
   }
}

Let us compile and run the above program, this will produce the following result −

Number = 2
Number = 1
Number = 9
Number = 6
Number = 4
The sorted int array is:
Number = 1
Number = 2
Number = 4
Number = 6
Number = 9
