Example

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

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
Value = 12
