title: sleep in Java web application
body: <p>I want to use Thread.sleep() in my java application. But does not work. Program works after removing sleep. </p>
  
  <p>In my program I am running multiple threads and want that each move forward at a variable speed. Some may get executed more some less. So I am using sleep in each with a random number as argument.
  If there another way to do this. Without using sleep. </p>
  
  <p>Here is the part where I am using the sleep function.</p>
  
  <pre><code>public void run()
      {
          Random r = new Random();
          int t;
          while(true)
          {
              if(total == 1)
              {
                  // win();
                  break;
              }
              if(doa == 1)
                  break;
              // Player x = e[r.nextInt(20)%2];
              Player x = choose();
              x.attack(this, 10 + (power==1?5:0));
              if(r.nextInt(100)%(5 - (power==2?2:0)) == 0)
                  System.out.println(" " + name + " used Potion effect (" + potionno++ + ") .. now " + name + "'s Health is " + (h+= 10 + r.nextInt(20))); 
              try
              {
                  sleep(50 + r.nextInt(1000));
              }
              catch(InterruptedException c)
              {       ; }
          }
          if(doa == 1)) {
  // and so on
  
  
  
     .

  <p>.</p>
  
  <p>and here is my doGet function used for initiation</p>
  
  <pre><code>public void doGet(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
          response.setContentType("text/html;charset=UTF-8");
          PrintWriter out = response.getWriter();
          String s;
          s = request.getParameter("name");           
          try{
             Player.out = out;
              Player.e[0] = new Player("Kartik",2);
              Player.e[1] = new Player(s,1);
              Player.e[2] = new Player("Anirudh",3);
              Player.e[3] = new Player("Vinita");
              Player.e[4] = new Player("Shivank");
  
              for(Player p: Player.   e)
                      p.start();
  
         }
             catch(Exception e)
             {
               out.print("WRONG");   
             }
      }
