本文探讨了线程join方法在多线程编程中的作用，通过实例展示了如何利用join确保主线程等待子线程完成操作，进而获取子线程处理结果的过程。

package org.sf.thread;
/**
* 线程join
* ，当主线程处理完其他的事务后，需要用到子线程的处理结果，这个时候就要用到join();方法了。
*
*/
public class ThreadJoinTest {

private int counter;
public class ThreadTesterA implements Runnable {
@Override
public void run() {
  while (counter <= 10) {
   System.out.print("Counter = " + counter + " ");
   counter++;
  }
  System.out.println();
}
}

class ThreadTesterB implements Runnable {

private int i;

@Override
public void run() {
  while (i <= 10) {
   System.out.print("i = " + i + " ");
   i++;
  }
  System.out.println();
}
}
public void init() throws InterruptedException{
Thread t1 = new Thread(new ThreadTesterA());
Thread t2 = new Thread(new ThreadTesterB());
t1.start();
t1.join(); // wait t1 to be finished
t2.start();
t2.join(); // in this program, this may be removed
}
