Java - Multithreading Example

An old example of threading in Java (Java doesn't natively support fork() ) :

import java.lang.Thread;
import java.lang.System;
import java.lang.Math;
import java.lang.InterruptedException;
import java.lang.Runnable;

class ThreadTest2 {
 public static void main(String args[]) {
  Thread thread1 = new Thread(new MyClass("thread1: "));
  Thread thread2 = new Thread(new MyClass("thread2: "));
  thread1.start();
  thread2.start();
  boolean thread1IsAlive = true;
  boolean thread2IsAlive = true;
  do {
   if(thread1IsAlive && !thread1.isAlive()){
    thread1IsAlive = false;
    System.out.println("Thread 1 is dead.");
   }
   if(thread2IsAlive && !thread2.isAlive()){
    thread2IsAlive = false;
    System.out.println("Thread 2 is dead.");
   }
  }while(thread1IsAlive || thread2IsAlive);
 }
}
class MyClass implements Runnable {
 static String message[] = {"Java","is","hot,","aromatic,","and",
  "invigorating."};
 String name;
 public MyClass(String id) {
  name = id;
 }
 public void run() {
  for(int i=0;<message.length;++i) {
   randomWait();
   System.out.println(name+message[i]);
  }
 }
 void randomWait(){
  try {
   Thread.currentThread().sleep((long)(3000*Math.random()));
  }catch (InterruptedException x){
   System.out.println("Interrupted!");
  }
 }
}
