A good answer might be:

Yes.

A method can catch some exceptions and not others. Since problems with closing a file are rare, not catching this one would be tolerable. But a commercial-grade program should take care of everything. Here is one way:

    try
    {
      // other stuff goes here


      try
      {
        while ( true )
          sum += instr.readInt();
      }
      catch ( EOFException eof )
      {
        System.out.println( "The sum is: " + sum );
        instr.close(); 
      }

    }

    catch ( IOException iox )
    {
      System.out.println( "IO Problems with" + fileName );
    }

The logic dealing with reading input and catching end of file is put inside a try{} block that is concerned with errors. This is a little messy, but IO programming always is.

QUESTION 11:

If the readInt() throws an IOException, where will it be caught?
