This document discusses exception handling in Ruby. It begins by explaining why exception handling is needed by describing errors, error codes, and their shortcomings. It then discusses Ruby's exception handling mechanisms which include the Exception class hierarchy, raising exceptions with raise, and handling exceptions with rescue blocks. Finally, it briefly covers catch/throw clauses which allow continuing execution up the call stack.
This document discusses exception handling in Java. It defines exceptions as events that disrupt normal program flow and explains how Java uses try, catch, throw, throws and finally keywords to handle exceptions. It describes different types of exceptions like compile-time errors, runtime errors, checked exceptions and unchecked exceptions. The key aspects of exception handling mechanism are to find the problem, inform of the error, receive error information and take corrective actions. The document provides examples of exception handling code and explains concepts like multiple catch blocks and finally block.
This chapter discusses exception handling in C++. It introduces exceptions as undesirable events detectable during program execution. Try/catch blocks are used to handle exceptions, where code that may trigger exceptions is placed in a try block and catch blocks specify the exception type and contain handling code. Catch blocks are checked in order to handle matching exceptions. The chapter covers built-in C++ exception classes and creating custom exception classes, as well as rethrowing, stack unwinding, and different techniques for exception handling.
This document discusses exception handling in Ruby. It begins by explaining why exception handling is needed by describing shortcomings of traditional error code handling methods. It then discusses Ruby's exception handling mechanisms, including the Exception class hierarchy, user-defined exceptions, and how to handle, raise, and catch/throw exceptions. Key aspects covered are the rescue and ensure blocks for handling exceptions, and the raise statement for deliberately raising exceptions. The document concludes that exception handling is essential for managing errors in object-oriented code like Ruby.
The document is a poem about the artist Vincent Van Gogh. It describes his paintings of starry nights and colorful landscapes. It references his mental illness and the darkness in his soul. It suggests that in his final days, when he saw no hope, he took his own life, as lovers often do, but he was too beautiful for this world.

This document discusses exception handling in Java. It defines the exception hierarchy and describes checked and unchecked exceptions. It explains how to use try, catch, throw, throws and finally to handle exceptions. Key points covered include using multiple catch blocks to handle different exception types, nested try blocks, and displaying exception descriptions. Exception handling allows fixing errors, preventing program termination, and improving robustness.
An exception is an error condition or unexpected behavior encountered during program execution. Exceptions are handled using try, catch, and finally blocks. The try block contains code that might throw an exception, the catch block handles the exception if it occurs, and the finally block contains cleanup code that always executes. Common .NET exception classes include ArgumentException, NullReferenceException, and IndexOutOfRangeException. Exceptions provide a standard way to handle runtime errors in programs and allow the programmer to define specific behavior in error cases.

The document discusses exception handling in Java. It defines exceptions as abnormal conditions that occur during runtime and disrupt normal program flow. It describes different types of exceptions like checked, unchecked, and errors. It explains concepts like exception handling syntax using try, catch, finally blocks to maintain program flow. It provides examples to demonstrate exception handling and resolving exceptions in catch blocks.
1. Exception handling separates error-handling code from normal code to make programs more readable and robust.
2. There are two main types of exceptions: checked exceptions which must be caught or declared, and unchecked exceptions which do not typically need to be caught.
3. The try-catch block is used to catch exceptions, where code after the try is run inside a try block and any matching exceptions are caught and handled in corresponding catch blocks.
The document discusses event handling and exceptions in Java. It covers event-driven programming, event classes, listeners, and delegation models. It also covers exception handling, common exception types like IOException and NullPointerException, using try/catch blocks to handle exceptions, and best practices for exception handling in Java programs.
The document discusses exception handling in Ruby programming. It begins with an introduction to exception handling and why it is important. Then it covers the main concepts of exception handling in Ruby, including raise, rescue, ensure, retry and else. It also discusses some caveats and guidelines for exception handling, such as only using exceptions for truly unexpected situations and avoiding exception abuse.
Exception handling in C++ provides a standard mechanism for processing errors. Exceptions indicate problems during a program's execution and exception handling allows a program to continue running or notify the user of problems. The key components are try blocks for code that could cause exceptions, catch handlers to handle specific exceptions, and stack unwinding to search for exception handlers up the call stack if an exception is not caught. Derived exception classes enable related errors to be caught together under a base class.

A Brief Outline
Exception Handling: WHY?
Errors and Error Codes
The Need for Exception Handling
Exception Handling in Ruby:
The Exception Class
Exception Class Heirarchy
Handling Exceptions
Raising Exceptions
Catch/Throw Clauses
Conclusions
3. ‘Exception Handling in RUBY’
Exception Handling: WHY?
Errors and Error Codes
Errors and Error Codes
In any programming, occurance of errors is a distinct reality.
Errors need to be handled gracefully to avoid abrupt failures.
Code that detects error may not have context to handle it.
For example, attempting to open a file that doesn’t exist is
acceptable in some circumstances and is a fatal error at other
times. What does the file-handling module do?
Conventionally it was done using error-checking and
return-codes mechanism.
Functions were checked for return values, and if the return
code indicated failure, this code was interpreted and passed
up the call stack.
4. ‘Exception Handling in RUBY’
Exception Handling: WHY?
The Need for Exception Handling
The Need for Exception Handling
However Error-codes mechanism has following shortcomings:
Handling all errors through error codes is simply not possible.
Moving error codes up the function call stack is complicated.
Managing all the error-codes and associated code is tedious.
The Exception Handling mechanism addresses these
shortcomings.
Exceptions allow packaging info about error in an object.
Exception handling helps propagate object up the call stack.
Runtime system locates code that knows to handle the error.
Exception handling is essential for achieving well-designed object
oriented code, and therefore Ruby provides a mechanism for same.
5. ‘Exception Handling in RUBY’
Exception Handling in Ruby
The Exception Class
The Exception Class
As in other object oriented languages, Ruby offers a
mechanism for exception handling.
When an exception occurs..
Object of class Exception, or one of it’s children, created.
Exception is associated to message string & a stack backtrace.
All information about the exception is packaged in this object.
IOError, ZeroDivisionError, TypeError, SystemCallError, etc
are examples of exceptions derived from class Exception.
Ruby predefines a hierarchy of exceptions: see next slide.
7. ‘Exception Handling in RUBY’
User Defined Exceptions
User Defined Exceptions
User-Defined Exception
Users can create exception classes of their own.
These must inherit from class StandardError or its children.
If they dont, such exceptions will not be detected by default.
They may include more specific information about the
exception.

Handling Exceptions
The basic approach to exception handling involves the use of:
Enclose candidate code in begin/end block.
Use rescue block to handle specific class of exceptions,
where:
Report the error,
Code to handle detected error,
Raise the exception using raise.
Use ensure block to ensure execution of some essential code
after handling, like deallocation of resources such as DB
connections, etc.
We can draw analogies to C++/Java exception handling:
begin/end block for candidate code. (like try block)
rescue blocks for handling code. (like catch blocks)
raise command for raising the exception. (like throw)
ensure command for necessary handling. (like final)

Variables
$ refers to the default global variable that stores the exception
object for the exception.
stderrobj is an example of user-defined variable storing the
reference to the exception object.
Matching exceptions to correct rescue block is like the case
statement mechanism,
object.kindof? result compared to exception types in
rescue statements.

Raising Exceptions
Raising Exceptions
Raising exceptions deliberately in code help to trigger alerts
where errors are expected and need to be handled.
The raise statement can take the following forms:
raise
Raises current exception again, or RuntimeError if none.
raise <message>
Creates new RuntimeError exception, associates it with
mentioned string, and raises the exception up the call stack.
raise <exception class>, <message>, <call stack>
Creates exception with arg-1 used as required exception type,
arg-2 as message string, and arg-3 as stack trace.

The Catch/Throw Clauses
The catch/throw Clauses
The rescue and raise mechanism is thus used for
abandoning execution when unwanted errors occur.
The catch and throw mechanism is used to continue
execution at some point up the call stack.
Working of catch/throw:
catch defines a block with a specific label.
The block is exeuted, typically accross nested functions, till a
throw followed by the label is encountered.
The call stack is then scoured for a catch block with a
matching label.
On a match, Ruby rolls back execution to the point and
terminates the block.
If the throw had an optional 2nd argument, it is returned as
value of the catch block.

Conclusions
Conclusions
Exception Handling is essential for managing errors in
object-oriented code.
The Ruby Exception Handling mechanism includes:
rescue and final clauses - for handling unwanted errors and
exit gracefully.
raise - for deliberately creating and raising exceptions in
code.
catch and throw clause - for continuing execution at some
point up the function call stack.
