Java Thread yield()方法

Thread類的yield()方法導致當前正在執行的執行緒物件暫停並允許其他執行緒執行。

語法

public static void yield()

範例

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");  
        }  
    }  
}

執行上面範例程式碼，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
