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 float array
    float arr[] = new float[] {1f, 5f, 3f, 2f, 9f};
    
    // let us print the values
    System.out.println("Actual values: ");
    for (float value : arr) {
      System.out.println("Value = " + value);
    }

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

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

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

Actual values:
Value = 1.0
Value = 5.0
Value = 3.0
Value = 2.0
Value = 9.0
New values after using fill() method:
Value = 12.0
Value = 12.0
Value = 12.0
Value = 12.0
Value = 12.0
