Possible Exceptions

In the example program, the try{} block might throw a NumberFormatException, or an ArithmeticException.

  public static void main ( String[] a ) 
     . . . .

    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 (InputMismatchException ex )
    {
      . . .
    }

    catch (ArithmeticException ex )
    {
      . . .
    }
  }

A NumberFormatException might occur in either call to nextInt(). The first catch{} block is for this type of exception.

An ArithmeticException might occur if the user enters data that can't be used in an integer division. The second a catch{} block is for this type of exception.
