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 byte array
    byte arr[] = new byte[] {1, 6, 3};
    
    // let us print the values
    System.out.println("Actual values: ");
    for (byte value : arr) {
      System.out.println("Value = " + value);
    }

    // using fill for placing 8
    // converting int to byte
    Arrays.fill(arr,(byte)8);

    // let us print the values
    System.out.println("New values after using fill() method: ");
    for (byte 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 = 6
Value = 3
New values after using fill() method:
Value = 8
Value = 8
Value = 8
