Using Synchronized Keyword in threads, but result is not correct?

I'm trying to make use of the keyword "synchronized" but the results are not correct. I'm not able to figure out why call to third object is given before the second one.

Expected Output:

hello
synchronized
world

Output - What i'm getting

hello
world
synchronized

Below is the code I am using:

class Callme{
 synchronized void call(String msg){
  System.out.print("["+msg);

 try{
Thread.sleep(1000);
 }catch(InterruptedException ie){}
   System.out.println("]");
     }  
      }


class Caller implements Runnable{
   String msg;
   Callme target;
   Thread t;
   public Caller(Callme targ, String s){
      target=targ;
      msg=s;
      t=new Thread(this);
      t.start();
    }

  public void run(){
  target.call(msg);
   } 

}
 class Synch{
 public static void main(String[] args){
    Callme target=new Callme();
    Caller c1=new Caller(target,"hello");
    Caller c2=new Caller(target,"Synchronized");
    Caller c3=new Caller(target,"world");

try{
   System.out.println("Waiting for the threads to end");
   c1.t.join();
   c2.t.join();
   c3.t.join();
   }catch(InterruptedException ie){} 

   }    
 }
