 try{}  and  catch{} 
Here is ONE form of the  try/catch structure
(there are other forms soon to be discussed):
try
{
  // statements, some of which might
  // throw an exception
}
catch ( SomeExceptionType ex )
{
  // statements to handle this
  // type of exception
}
....  // more catch blocks
catch ( AnotherExceptionType ex )
{
  // statements to handle this
  // type of exception
}
// Statements following the structure
Here are a few syntax rules:
try{} block can include:
    catch{} blocks following the try() block.
    catch{} block.  
        This will be discussed in a few pages.catch{} block describes the type of exception it handles.Is the following code fragment OK?
    try
    {
      // various statements
    }
    catch (InputMismatchException ex )
    {
      // various statements
    }
    catch (IOException ex )
    {
      // various statements
    }
    System.out.println("Good-by" );
