LinkedBlockingDeque remainingCapacity() method in Java

Last Updated : 17 Sep, 2018

The remainingCapacity() method of LinkedBlockingDeque returns the number of additional elements that this deque can ideally (in the absence of memory or resource constraints) accept without blocking.

remainingCapacity() = final_size() - current_size()

Syntax:

public int remainingCapacity()

Parameters: This method does not accepts any parameters. Returns: This method returns the remaining number of elements that can be inserted into the deque container. Below programs illustrate remainingCapacity() method of LinkedBlockingDeque: Program 1:

Java

// Java Program Demonstrate remainingCapacity() // method of LinkedBlockingDeque // when initial size is mentioned  import java.util.concurrent.LinkedBlockingDeque; import java.util.*;  public class GFG {     public static void main(String[] args)         throws InterruptedException     {          // create object of LinkedBlockingDeque         LinkedBlockingDeque<Integer> LBD             = new LinkedBlockingDeque<Integer>(6);          // Add numbers to end of LinkedBlockingDeque         LBD.add(7855642);         LBD.add(35658786);         LBD.add(5278367);         LBD.add(74381793);          // print Dequeue         System.out.println("Linked Blocking Deque: " + LBD);         System.out.println("remainingCapacity = : " +                                LBD.remainingCapacity());     } }

Output:

  Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]  remainingCapacity = : 2

Program 2:

Java

// Java Program Demonstrate remainingCapacity() // method of LinkedBlockingDeque // when no initial size is mentioned  import java.util.concurrent.LinkedBlockingDeque; import java.util.*;  public class GFG {     public static void main(String[] args)         throws InterruptedException     {          // create object of LinkedBlockingDeque         LinkedBlockingDeque<Integer> LBD             = new LinkedBlockingDeque<Integer>(6);          // Add numbers to end of LinkedBlockingDeque         LBD.add(7855642);         LBD.add(35658786);         LBD.add(5278367);         LBD.add(74381793);          // print Dequeue         System.out.println("Linked Blocking Deque: " + LBD);         System.out.println("remainingCapacity = " +                               LBD.remainingCapacity());     } }

Output:

  Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]  remainingCapacity = 2
