well, An exception is an error thrown by a class or method reporting an error in operation. For example, dividing by zero is undefined in mathematics, and a calculation can fail if this winds up being the case because of an error in user input. In this particular case an ArithmeticException is thrown, and unless the programmer looks for this exception and manually puts in code to handle it

Hi Dinesh,Before answering your question, you need to understand what is an Exception first.An exception is an event that occurs during the execution of a program that disrupts the normal flow of instructions. Or in other words, its a bug in a program that needs to be found and fixed.Finding that event exception and having found it, what you would do with that exception is normally referred as Exception

An exception handler designed to handle a specific type of object may be pre-empted by another handler whose exception type is a superclass of that type. This happens if the exception handler for that exception type appears earlier in the list of exception handlers.For example:try my result = self->dividevalue, 0; divide throws DivideByZeroExceptionreturn result;catch MathException with my ex = shift

well, RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.A method is not required to declare in its throws clause any subclasses of RuntimeException that might be thrown during the execution of the method but not caught.Since: JDK1.0See Also: Serialized FormConstructor SummaryRuntimeException Constructs a new runtime

This class is the base class for all Exceptions.When an error occurs, either the system or the currently executing application reports it by throwing an exception containing information about the error. Once thrown, an exception is handled by the application or by the default exception handler.Yes - the feature which stands out is the StackTrace property. This provides a call stack which records

well,Yes - the feature which stands out is the StackTrace property. This provides a call stack which records where the exception was thrown from. For example, the following code: using System; class CApp public static void Main try f; catch Exception e Console.WriteLine "System.Exception stack trace = n0", e.StackTrace ; static void f throw new Exception "f went pear

PL/SQL exception handling is a mechanism for dealing with run-time errors encountered during procedure execution. Use of this mechanism enables execution to continue if the error is not severe enough to cause procedure termination.The exception handler must be defined within a subprogram specification. Errors cause the program to raise an exception with a transfer of control to the exception

The C language provides built-in language features to raise and handle exceptions. These language features activate a run-time mechanism used to communicate exceptions between two unrelated often separately developed portions of a C program.When an exception is encountered in a C program, the portion of the program that detects the exception can communicate that the exception has occurred by raising

well Nikhil,Multiple threads or exception handling further add to the complexity of manual deallocation. For example, various C newsgroups and mailing lists have carried extensive discussions about the proper way to deallocate partially constructed C objects in response to an exception. Such issues disappear in the presence of a garbage collector. However, some see checked exceptions as a nuisance

A checked exception is any subclass of Exception or Exception itself, excluding class RuntimeException and its subclasses. Making an exception checked forces client programmers to deal with the possibility that the exception will be thrown. eg, IOException thrown by java.io.FileInputStreams read method Unchecked exceptions are RuntimeException and any of its subclasses. Class Error and its subclasses

Exception handling is a programming language construct or computer hardware mechanism designed to handle the occurrence of some condition that changes the normal flow of execution. The condition is called an exception. Exceptions are normally recommended to be used only for signaling error (exceptional) conditions. For signaling conditions that are part of the normal flow of execution see

like a C pointer than a C reference. If you try to use a null reference, a NullReferenceException is thrown.For example, look at the following method:void displayStringLength string s Console.WriteLine "String is length 0", s.Length ;The problem with this method is that it will throw a NullReferenceException if called like this:string s = null;displayStringLength s ;Of course for some
