設置線程的優先級數值

setName()

給線程一個名字

getName()

取得線程的名字

currentThread()

public class ThreadTest3 {

public static void main(String[] argc) throws Exception {

Runnable r = new

Thread t = new Thread(r, "Name test");

t.start();

System.out.println("name is: " + t.getName());

Thread.currentThread().sleep(5000);

System.out.println(t.isAlive());

System.out.println("over!");

}

}

class Thread6 implements Runnable {

public void run() {

for (int i = 0; i < 100; i++)

System.out.println(i);

}

}

public class ThreadTest4 {

public static void main(String[] args) {

Thread t1 = new Thread(new Thread7(), "t1");

Thread t2 = new Thread(new Thread7(), "t2");

t1.setPriority(1);

t2.setPriority(10);

t1.start();

t2.start();

}

}

class Thread7 extends Thread {

public void run() {

for (int i = 0; i < 20; i++) {

System.out.println(Thread.currentThread().getName() + ": " + i);

// yield();

}

}
