Java 中的 ArrayBlockingQueue clear ()方法
Java中ArrayBlockingQueue类的clear()方法用于从该队列中删除所有元素。
语法如下
public void clear()
要使用ArrayBlockingQueue类，您需要导入以下包
import java.util.concurrent.ArrayBlockingQueue;
下面是一个实现JavaArrayBlockingQueue类的clear()方法的示例
示例
import java.util.ArrayList;
import java.util.Iterator;
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(120);
q.add(10);
q.add(400);
q.add(450);
q.add(500);
q.add(550);
q.add(700);
System.out.println("ArrayBlockingQueue = " + q);
q.remove();
System.out.println("Updated ArrayBlockingQueue = " + q);
q.clear();
System.out.println("Updated ArrayBlockingQueue = " + q);
}
}输出结果
ArrayBlockingQueue = [120, 10, 400, 450, 500, 550, 700] Updated ArrayBlockingQueue = [10, 400, 450, 500, 550, 700] Updated ArrayBlockingQueue = []
