Exception Handling

Updated Jun 12, 2020 ·

Overview​

Good error handling helps keep software safe and working properly. It prevents bugs and security issues by catching and managing problems before they cause damage.

Key Points​

  • Unexpected Behavior

    • Software can fail when invalid input is processed.
    • Error handling prevents unpredictable states.

  • State Transitions

    • Software should transition smoothly between defined states.
    • Errors can disrupt these transitions, leading to vulnerabilities.

  • Importance of Exception Handling

    • Provides explicit instructions for error situations.
    • Helps maintain software integrity and security.

Example of Exception Handling in Java​

  • Try-Catch Structure
    • Code is enclosed in a try block to attempt an operation.
    • A catch block captures specific exceptions, like division by zero.
  • User Feedback
    • Reports errors back to the user for clarity.
    • Ensures the program can handle issues without crashing.
