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 a long array
		long arr[] = new long[] { 100, 200, 300, 400, 500 };
		// Print the original array
		System.out.println("Original Array : ");
		for (long val : arr) {
			System.out.println("Original element is " + val);
		}
		// Use fill to place 50
		Arrays.fill(arr, 50);
		// Print the new array
		System.out.println("\nNew Array is : ");
		for (long 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 a long array

long arr[] = new long[] { 100, 200, 300, 400, 500 };

// Print the original array

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

for (long val : arr) {

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

}

// Use fill to place 50

Arrays.fill(arr, 50);

// Print the new array

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

for (long val : arr) {

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

}

Output of Program :

Original Array : 
Original element is 100
Original element is 200
Original element is 300
Original element is 400
Original element is 500
New Array is : 
New element is 50
New element is 50
New element is 50
New element is 50
New element is 50

Original Array :

Original element is 100

Original element is 200

Original element is 300

Original element is 400
