TAILIEUCHUNG - Object Oriented Programming - Lesson 10: Exception Handling

Object Oriented Programming - Lesson 10: Exception Handling presents Exception & Exception handling, Exception classes hierarchy, try/catch/finally blocks, Throwing exceptions, Print a stack trace message, Making custom exceptions. | LESSON X. Exception Handling Trinh Thanh TRUNG (MSc) trungtt@ Objectives • After this lesson, students (learners) can: – Learn what an exception is, what have to do to handle exception – Distinguish the checked and unchecked exceptions – Implement the try-catch-finally blocks for catching and handling exceptions – Write methods that propagate exceptions. – Write programmer-defined exception classes. Content I. Exception & Exception handling II. Exception classes hierarchy III. try/catch/finally blocks IV. Throwing exceptions V. Print a stack trace message VI. Making custom exceptions I. Exception and Exception Handling 1. Exception 2. Exception Handling 1. Exception-What are errors? • There are three categories or types of errors: – (1) Syntax errors – (2) Logic errors (sometimes called: semantic errors) – (3) Runtime errors • Syntax errors arise because the rules of the language have not been followed. They are detected by the compiler. • Logic errors occur when a program doesn't perform the way it was intended to. • Runtime errors occur while the program is running if the environment detects an operation that is impossible to carry .
