The following example shows the usage of java.util.Arrays.toString() method.

package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {

   public static void main(String[] args) {

    // initializing int array
    int[] i1 = new int[] { 33, 12, 98 };

    // let us print all the elements available in list
    System.out.println("The array is:");
    for (int number : i1) {
      System.out.println("Number = " + number);
    }
	
    System.out.println("The string representation of array is:");
    System.out.println(Arrays.toString(i1));    
  }
}

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