First Thank you for taking a look at this at this time of the night.

Dont mind saying you are stupid....

but here is my code and the error i get

  
new ThreadOne();
        new ThreadTwo();
        int calc;
        try{
            for(int j = 0; j<=5; j++ )
                calc = j *(500 - j);
                System.out.println("in Main Thread Multiplying :" + calc);     //its saying "variable calc might not have been initialized"
                Thread.sleep(200);
        }
        catch(InterruptedException e){
            System.out.println("Main thread interupted");
        }

why does it let me assign value to it if it is not initialized? or am i missing something when i say calc?
Help please

One thing for sure... the Java compiler is not stupid
Indent your code correctly and it will become obvious

      try {
         for(int j = 0; j<=5; j++ )
            calc = j *(500 - j);
         System.out.println("in Main Thread Multiplying :" + calc);

OK you probably have { missing for your for() loop that will include the calculation of calc and its printout.
You can argue that the for() will be executed at least once even if an exception is throwed the compiler is not that smart (contrary to you )
