Java中的ArrayBlockingQueue take()方法
take()
ArrayBlockingQueue类的方法获取并删除此队列的头部,如有必要,请等待直到元素可用。
语法如下
public E take() throws InterruptedException
要使用ArrayBlockingQueue类,您需要导入以下包
import java.util.concurrent.ArrayBlockingQueue;
以下是实现take()
JavaArrayBlockingQueue类的方法的示例
示例
import java.util.concurrent.ArrayBlockingQueue; public class Demo { public static void main(String[] args) throws InterruptedException { ArrayBlockingQueue<Integer> q = new ArrayBlockingQueue<Integer>(10); q.add(200); q.add(310); q.add(400); q.add(450); q.add(500); q.add(550); q.add(700); System.out.println("ArrayBlockingQueue = " + q); System.out.println("The head of the queue = "+q.take()); //添加更多元素 q.add(50); q.add(70); q.add(90); System.out.println("ArrayBlockingQueue = " + q); System.out.print("The head of the queue = "+q.take()); } }
输出结果
ArrayBlockingQueue = [200, 310, 400, 450, 500, 550, 700] The head of the queue = 200 ArrayBlockingQueue = [310, 400, 450, 500, 550, 700, 50, 70, 90] The head of the queue = 310
