Declaration :

public static void fill(float[] a, float val)

1	public static void fill(float[] a, float val)

Explanation :

Purpose	The java.util.Arrays.fill(float[] a float val) method assigns the specified float value to each element of the specified array of floats.
Parameters	a ===> This is the array to be filled.
	val ===> This is the value to be stored in all elements of the array.
Return Value	This method does not return any value.
Exception	NA

Java Program : Example

Below example will explain java.util.Arrays.fill() method.

package com.c4learn;
import java.util.Arrays;
public class ArrayDemo {
	public static void main(String[] args) {
		// Initialize float array
		float arr[] = new float[] { 10f, 20f, 30f, 40f, 50f };
		// Print the original array
		System.out.println("Original Array : ");
		for (float val : arr) {
			System.out.println("Original element is " + val);
		}
		// Use fill to place 25
		Arrays.fill(arr, 25f);
		// Print the new array
		System.out.println("\nNew Array is : ");
		for (float val : arr) {
			System.out.println("New element is " + val);
		}
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize float array

float arr[] = new float[] { 10f, 20f, 30f, 40f, 50f };

// Print the original array

System.out.println("Original Array : ");

for (float val : arr) {

System.out.println("Original element is " + val);

}

// Use fill to place 25

Arrays.fill(arr, 25f);

// Print the new array

System.out.println("\nNew Array is : ");

for (float val : arr) {

System.out.println("New element is " + val);

}

Output of Program :

Original Array : 
Original element is 10.0
Original element is 20.0
Original element is 30.0
Original element is 40.0
Original element is 50.0
New Array is : 
New element is 25.0
New element is 25.0
New element is 25.0
New element is 25.0
New element is 25.0

Original Array :

Original element is 10.0

Original element is 20.0

Original element is 30.0

Original element is 40.0

Original element is 50.0

New Array is :

New element is 25.0
