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:
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws InterruptedException
{
LinkedBlockingDeque<Integer> LBD
= new LinkedBlockingDeque<Integer>( 6 );
LBD.add( 7855642 );
LBD.add( 35658786 );
LBD.add( 5278367 );
LBD.add( 74381793 );
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:
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws InterruptedException
{
LinkedBlockingDeque<Integer> LBD
= new LinkedBlockingDeque<Integer>( 6 );
LBD.add( 7855642 );
LBD.add( 35658786 );
LBD.add( 5278367 );
LBD.add( 74381793 );
System.out.println( "Linked Blocking Deque: " + LBD);
System.out.println( "remainingCapacity = " +
LBD.remainingCapacity());
}
}
|
Output:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
remainingCapacity = 2
