Exception handling with Apex (force.com)

Question

Is there any way to throws an standard or custom exception with Apex method as,

 private void createNewJob() throws RecordNotFoundException { 

  try {         
         // Some DML operation                
      } catch (Exception e) {  
         System.Debug('Error: Object not found');
         throw new RecordNotFoundException('Object not found');
      }
  }

Answer 1

Yes.

Define the exception class. Minimally, :

public class RecordNotFoundException extends Exception { }

Your throw statement looks fine.

Also, there's no need to declare that the method throws an exception type.
