Java使用join方法暂停当前线程

java;">package Threads;import java.io.IOException;/** * Created by Frank */public class Join { public static void main(String[] args) {  Thread t = new Thread() {   public void run() {    System.out.println("Reading");    try {     System.in.read();    } catch (IOException e) {     System.err.println(e);    }    System.out.println("Thread finished.");   }  };  System.out.println("Starting");  t.start();  System.out.println("Joining");  try {   t.join();  } catch (InterruptedException e) {   // 不应该发生   System.err.println("Who dares interrupt my sleep??");  }  System.err.println("Main Finished"); }}
