Java Thread yield()方法

Thread類的yield()方法導致當前正在執行的線程對象暫停並允許其他線程執行。

語法

public static void yield()

示例

public class JavaYieldExp extends Thread
{
    public void run()
    {
        for (int i=0; i<3 ; i++)
            System.out.println(Thread.currentThread().getName() + " in control");
    }
    public static void main(String[]args)
    {
        JavaYieldExp t1 = new JavaYieldExp();
        JavaYieldExp t2 = new JavaYieldExp();
        // this will call run() method
        t1.start();
        t2.start();
        for (int i=0; i<3; i++)
        {
            // Control passes to child thread
            t1.yield();
            System.out.println(Thread.currentThread().getName() + " in control");
        }
    }
}

執行上面示例代碼，得到以下結果：

main in control
main in control
main in control
Thread-0 in control
Thread-0 in control
Thread-0 in control
Thread-1 in control
Thread-1 in control
Thread-1 in control
