Java中的ArrayBlockingQueue remainingCapacity方法
Java中ArrayBlockingQueue类的remainingCapacity()方法用于返回队列可以在不阻塞的情况下采用的附加元素的数量。
语法如下
int remainingCapacity()
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remainingCapacity()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(120);
q.add(400);
q.add(450);
q.add(500);
System.out.println("ArrayBlockingQueue = " + q);
System.out.println("ArrayBlockingQueue Remaining Capacity = " + q.remainingCapacity());
q.add(620);
q.add(700);
System.out.println("ArrayBlockingQueue = " + q);
System.out.println("ArrayBlockingQueue Remaining Capacity = " + q.remainingCapacity());
q.add(820);
q.add(900);
q.add(950);
System.out.println("ArrayBlockingQueue = " + q);
System.out.println("ArrayBlockingQueue Remaining Capacity = " + q.remainingCapacity());
}
}输出结果
ArrayBlockingQueue = [120, 400, 450, 500] ArrayBlockingQueue Remaining Capacity = 6 ArrayBlockingQueue = [120, 400, 450, 500, 620, 700] ArrayBlockingQueue Remaining Capacity = 4 ArrayBlockingQueue = [120, 400, 450, 500, 620, 700, 820, 900, 950] ArrayBlockingQueue Remaining Capacity = 1
