Java LinkedBlockingDeque remove()用法及代码示例

LinkedBlockingDeque的remove()方法将删除Deque容器的头部。如果Deque容器为空，则此方法引发NoSuchElementException。

用法:

public E remove()

参数：此方法不接受任何参数。

返回值：此方法不返回任何内容。

异常：如果Deque为空，则该函数将引发NoSuchElementException。

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

示例1:

// Java Program Demonstrate remove() 
// method of LinkedBlockingDeque 
  
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>(); 
  
        // 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); 
  
        // removes the front element 
        LBD.remove(); 
        System.out.println("Linked Blocking Deque: " + LBD); 
    } 
}

输出：

Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
Linked Blocking Deque: [35658786, 5278367, 74381793]

示例2:

// Java Program Demonstrate remove() 
// method of LinkedBlockingDeque 
  
import java.util.concurrent.LinkedBlockingDeque; 
import java.util.*; 
  
public class GFG { 
    public static void main(String[] args) 
        throws NoSuchElementException 
    { 
  
        // 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); 
  
        // Deque is empty 
        LBD.clear(); 
  
        // throws an exception 
        LBD.remove(); 
    } 
}

输出：

Exception in thread "main" java.util.NoSuchElementException
    at java.util.concurrent.LinkedBlockingDeque.removeFirst(LinkedBlockingDeque.java:453)
    at java.util.concurrent.LinkedBlockingDeque.remove(LinkedBlockingDeque.java:672)
    at GFG.main(GFG.java:30)
