[nav katoch]

Consider the following code snippet:

void m1() throws Exception
{
   try
   {
      // line1
   }
   catch (IOException e)
   {
       throw new SQLException();
   }
   catch(SQLException e)
   {
       throw new InstantiationException();
   }
   finally
   {
      throw new CloneNotSupportedException()   // this is not a RuntimeException.
   }
}

Which of the following statements are true?

A. If IOException gets thrown at line1, then the whole method will end up throwing SQLException.
B. If IOException gets thrown at line1, then the whole method will end up throwing CloneNotSupportedException.
C. If IOException gets thrown at line1, then the whole method will end up throwing InstantiationException()
D. If no exception is thrown at line1, then the whole method will end up throwing CloneNotSupportedException.
E. If SQLException gets thrown at line1, then the whole method will end up throwing InstantiationException()

Answers:- B, D

Could anybody please explain?

Thanks!!!

Hint: Whatever the case finally block will always execute if your code reaches in try{}catch block, until you use System.exit();

[James Tharakan]

1--if there exists a finally block after try or catch block ,it does not matter(except system.exit) what happens in the try or catch block the finally block will be exectued.

one exception would be discarded if another exception is thrown before handling the first one.
Hope this two points help you in figuring out the answer.
[EDIT: Oops ! i did not notice punit's hint. Sorry gave away the answer ! !]
