Example

The following example shows the usage of java.util.ArrayDeque.removeLastOccurrence(o) method.

package com.tutorialspoint;

import java.util.ArrayDeque;
import java.util.Deque;

public class ArrayDequeDemo {
   public static void main(String[] args) {
      
      // create an empty array deque with an initial capacity
      Deque<Integer> deque = new ArrayDeque<Integer>(5);

      // use add() method to add elements in the deque
      deque.add(15);
      deque.add(20);
      deque.add(25);
      deque.add(20);

      // let us print all the elements available in deque
      for (Integer number : deque) {
         System.out.println("Number = " + number);
      }

      // this will remove last occurrence of element 20
      deque.removeLastOccurrence(20);

      System.out.println("Remaining Elements:");
      // let us print all the elements available in deque
      for (Integer number : deque) {
         System.out.println("Number = " + number);
      }
   }
}

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

Number = 15
Number = 20
Number = 25
Number = 20
Remaining Elements:
Number = 15
Number = 20
Number = 25
