Java 中 LinkedBlockingDeque take()方法
原文:https://www . geeksforgeeks . org/linkedblockingrequest-take-method-in-Java/
的 take() 方法链接锁定请求返回并从中移除德格集装箱的头部。如果在等待时被中断,该方法将抛出中断异常。
语法:
public E take()
返回:该方法返回德格容器的头部。
异常:如果在等待时被中断,该功能会抛出中断异常。
下面的程序说明了 link edblockingrequest 的 take()方法:
节目 1:
// Java Program to demonstrate take()
// 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 and prints it
System.out.println("Head of Linked Blocking Deque: "
+ LBD.take());
// prints the Deque
System.out.println("Linked Blocking Deque: " + LBD);
}
}
输出:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
Head of Linked Blocking Deque: 7855642
Linked Blocking Deque: [35658786, 5278367, 74381793]
程序 2: 演示中断异常
// Java Program to demonstrate take()
// 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>();
// print Dequeue
// the Deque is empty
System.out.println("Linked Blocking Deque: " + LBD);
try {
// throws error as the list is empty
// and it is interrupted while waiting
System.out.println("Head of Linked Blocking Deque: "
+ LBD.take());
}
catch (Exception e) {
System.out.println("Exception: " + e);
}
}
}
