Exception Catch-all

If the last catch block catches Exception, then it will catch any specific Exception not caught in the preceeding blocks. Do this so the user sees a pleasant error message rather than a confusing stack trace. Here is part of the program:

    try
    { 
      System.out.print("Enter the numerator: ");
      num = scan.nextInt();
      System.out.print("Enter the divisor  : ");
      div = scan.nextInt();
      System.out.println( num + " / " + div + " is " + (num/div) + " rem " + (num%div) );
    } 
    catch (ArithmeticException ex )
    { 
      System.out.println("You can't divide " + num + " by " + div);
    } 
    catch (Exception ex )
    { 
      System.out.println("Something went wrong." );
    }
   
    System.out.println("Good-by" );

Now specific arithmetic exceptions are caught in the first block, and everything else in the other.
