三个线程按照顺序依次执行
/**
* thread.Join把指定的线程加入到当前线程,可以将两个交替执行的线程合并为顺序执行的线程。
* 比如在线程B中调用了线程A的Join()方法,直到线程A执行完毕后,才会继续执行线程B
*/
public class JoinMain {
public static void main(String[] args) {
final Thread thread1 = new Thread(new Runnable() {
@Override
public void run() {
System.out.println("t1 begin");
}
},"t1");
final Thread thread2 = new Thread(new Runnable() {
@Override
public void run() {
try {
thread1.join(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("t2 begin");
}
},"t2");
Thread thread3 = new Thread(new Runnable() {
@Override
public void run() {
try {
thread2.join(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("t3 begin");
}
},"t3");
thread1.start();
thread2.start();
thread3.start();
