java 教程相应的代码 全是自己写的内附注释 很容易看明白的

package demo.chapter09.join;

public class JoinDemo {

	public static void main(String[] args) throws InterruptedException {
		
		class Runner implements Runnable {
			@Override
			public void run() {
				for (int i = 0; i < 10000; i++) {
					if (i % 100 == 0) {
						String name = Thread.currentThread().getName();
						System.out.println(name + ":" + i / 100);
						try {
							Thread.sleep(10);
						} catch (InterruptedException e) {
							e.printStackTrace();
						}
					}
				}
			}
		}
		
		Thread t = new Thread(new Runner());
		t.setName("线程1");
		Thread.currentThread().setName("主线程");
		t.start(); // 线程要在启动状态
		t.join(500);
		
		for (int i = 0; i < 10000; i++) {
