Multithread and join

Question

public class MyTest
     public static void main(String[] args) throws IOException
     {  System.out.println("starting main thread");
          new SimpleThread("Jamaica").start();
        new SimpleThread("Fiji").start();
          join(); // process main thread when all multithread finised. whats the correct syntax ?
           System.out.println("ending main thread");
class SimpleThread extends Thread {
             public SimpleThread(String str) {
                 super(str);
             public void run() {
                 for (int i = 0; i < 10; i++) {
                     System.out.println(i + " " + getName());
                     try {
                         sleep((int)(Math.random() * 1000));
                     } catch (InterruptedException e) {}
                 System.out.println("DONE! " + getName());
         }of course, this code will not work. but i want to do something like that . can i make it working ?

Answer 1

no, this way it can not work. now, first thread is finishing first . after that, second thread is finished and at last the main thread is finished.
i did not want this.
i wanted first and second thread should do as they do but when both of them are done , they should print
System.out.println("ending main thread");
can not join() do this ?
test code :
import java.io.*;
public class MyTest
     public static void main(String[] args) throws Exception
     {  System.out.println("starting main thread");
          //new SimpleThread("Jamaica").start();
        //new SimpleThread("Fiji").start();
          SimpleThread t[]=new SimpleThread[3];
          for (int i = 0;i<2; i++) {
                         t=new SimpleThread(i+"");
                         t[i].start();
                         t[i].join();
          // process main thread when all multithread finised. whats the correct syntax ?
          System.out.println("ending main thread");
class SimpleThread extends Thread {
public SimpleThread(String str) {
super(str);
public void run() {
for (int i = 0; i < 10; i++) {
System.out.println(i + " " + getName());
try {
sleep((int)(Math.random() * 1000));
} catch (InterruptedException e) {}
System.out.println("DONE! " + getName());
