Java LinkedBlockingDeque remainingCapacity()用法及代码示例

LinkedBlockingDeque的remainingCapacity()方法返回此双端队列在没有阻塞的情况下理想情况下可以接受的其他元素的数量(在没有内存或资源约束的情况下)。

remainingCapacity() = final_size() – current_size()

用法:

public int remainingCapacity()

参数：此方法不接受任何参数。

返回值：此方法返回可以插入双端队列容器的剩余元素数。

以下示例程序旨在说明LinkedBlockingDeque的remainingCapacity()方法：

示例1:

// 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()); 
    } 
}

输出：

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

示例2:

// 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()); 
    } 
}

输出：

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