package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {

   public static void main(String[] args) {
    
   // initializing long array
   long arr[] = new long[] {1, 16, 34, 149, 17};
    
   // let us print the values
   System.out.println("Actual values: ");
   for (long value : arr) {
   System.out.println("Value = " + value);
   }

   // using fill for placing 12
   Arrays.fill(arr, 12);

   // let us print the values
   System.out.println("New values after using fill() method: ");
   for (long value : arr) {
   System.out.println("Value = " + value);
   }
   }
} 

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

Actual values:
Value = 1
Value = 16
Value = 34
Value = 149
Value = 17
New values after using fill() method:

Value = 12
Value = 12
Value = 12
Value = 12
