Java多线程练习三

public class ex5 {
	public static void main(String [] args) {
		thread5 t1 = new thread5();
		thread5_1 t2 = new thread5_1();
		t1.setPriority(Thread.NORM_PRIORITY+3);
		t1.start();
		t2.start();
		for(int i=1;i<=100;i++) {
			System.out.println("3---"+i);
		}
	}
}

class thread5 extends Thread {
	public void run() {
		for(int i =1;i<=100;i++)
			System.out.println("1---"+i);
	}
}

class thread5_1 extends Thread {
	public void run() {
		for(int i = 1;i<=100;i++)
			System.out.println("2---"+i);
	}
}

测试了下线程优先级，后面的是线程yield方法练习

public class ex4 {
	public static void main(String [] args) {
		thread4 t1 = new thread4("tt1");
		thread4 t2 = new thread4("tt2");
		t1.start();
		t2.start();
	}
}

class thread4 extends Thread {
	thread4(String a) {
		super(a);
	}

	public void run() {
		for(int i=1;i<20;i++) {
			System.out.println("nihao"+getName());
			if(i%3==0)
				yield();
		}
	}
}
