    • 1) Introduction to Exception Handling
    • 2) Categories of Exceptions
    • 3) Creating a method that throws an exception
    • 4) Creating Custom Exception Classes
    • 5)What happens when an exception is thrown?
      • 5.1) Creating try-catch-finally blocks
      • 5.2) Using a method that throws a checked exception
      • 5.3) Using a method that throws a runtime exception
      • 5.4) Using a method that throws an error
      • 5.5) Will a finally block execute even if the catch block defines a return statement?
      • 5.6) What happens if both a catch and a finally block define return statement?
      • 5.7) What happens if a finally block modifies the value returned from a catch block?
      • 5.8) Can a try block be followed only by a finally block?
      • 5.9) Does the order of the exceptions caught in the catch blocks matter?
      • 5.10) Can I rethrow an exception or the error I catch?
      • 5.11) Can I declare my methods to throw a checked exception instead of handling it?
      • 5.12) I can create nested loops, so can I create nested try-catch blocks too?
      • 5.13) Should I handle errors?
