Java Program : Example

Below example will explain java.util.ArrayDeque.toArray() method.

package com.c4learn;
import java.util.ArrayDeque;
import java.util.Deque;
public class ArrayDequeDemo {
   public static void main(String[] args) {
      // Create empty array deque with an initial capacity
      Deque<Integer> deque = new ArrayDeque<Integer>(8);
      // Use add() method to add elements
      deque.add(100);
      deque.add(200);
      deque.add(300);
      deque.add(400);        
      deque.add(500);        
      // Print all the elements available in deque
      for (Integer number : deque) {
         System.out.println("Element is " + number);
      } 
      // Print size of the Array
      Object[] obj = deque.toArray();
      System.out.println("Size of Array is : " + obj.length);
   }
}

package com.c4learn;

import java.util.ArrayDeque;

import java.util.Deque;

public class ArrayDequeDemo {

public static void main(String[] args) {

// Create empty array deque with an initial capacity

Deque<Integer> deque = new ArrayDeque<Integer>(8);

// Use add() method to add elements

deque.add(100);

deque.add(200);

deque.add(300);

deque.add(400);

deque.add(500);

// Print all the elements available in deque

for (Integer number : deque) {

System.out.println("Element is " + number);

}

// Print size of the Array

Object[] obj = deque.toArray();

System.out.println("Size of Array is : " + obj.length);

}

Output of Program :

Element is 100
Element is 200
Element is 300
Element is 400
Element is 500
Size of Array is : 5

Element is 100

Element is 200

Element is 300

Element is 400

Element is 500

Size of Array is : 5
