Program Plan Intro

Exception:

  • • It is nothing but an undesirable or unexpected event that occurs at run time which interrupts the normal flow of the program’s commands.
  • • Exception handling is a mechanism that handle runtime errors like “ClassNotFoundException”, “SQLException”, and so on.
  • • An advantage of exception handling is to maintain a flow of the program.
  • • An exception can be handled using “try” and “catch” block.

Suppose the exception class CrazyException is defined as follows: public class CrazyException extends Exception { public CrazyException() { super("Crazy exception thrown!"); System.out.println("Wow, Crazy exception thrown!"); } public CrazyException(String message) { super(message); System.out.println("Wow, crazy exception thrown with "+ "an argument!"); } public void crazyMethod() { System.out.println("Message is " + getMessage()); } } What output would be produced by the following unlikely code? CrazyException exceptionObject = new CrazyException(); System.out.println(exceptionObject.getMessage()); exceptionObject.crazyMethod();
Suppose the exception class TestException is defined as follows:public class TestException extends Exception{public TestException(){super("Test Exception thrown!");System.out.println("Test exception thrown!!");}public TestException(String message){super(message);System.out.println("Test exception thrown with an argument!");}public void testMethod(){System.out.println("Message is " + getMessage());}}What output would be produced by the following code (which is just anexercise and not likely to occur in a program)?TestException exceptionObject = new TestException();System.out.println(exceptionObject.getMessage());exceptionObject.testMethod();The class TestException is on the website that comes with this text.
in python language , select the good example of the definition of a custom exception type? class InputErrorException: def __init__(self, value): self.value = value return value defInputErrorException:def__init__(self,value):self.value=value   classInputError(Exception):def__init__(self,value):self.value=value   defInputError(Exception):def__init__(self,value):self.value=valuereturnself.value
