TOPICS OF DISCUSSION:

EXCEPTION

A process  that used in responding to the occurrence, during computation of exceptions : anomalous or exceptional conditions requiring special processing

changing the normal flow of program execution

EXCEPTION HANDLING?

Exceptions due to programming errorsclient code errorsresource failures

NATURE OF EXCEPTIONS

Null pointer Errors: Runtime Exception

EXCEPTIONS DUE TO PROGRAMMING ERRORS

Illegal Exception ErrorA runtime error

EXCEPTIONS DUE TO PROGRAMMING ERRORS

Client code attempts something not allowed by the API

This Exception contains useful information about the location in the XML document that causes the problem

The client can use this information to take recovery steps.

HOW EXCEPTION CAN BE HANDLED

Fatema Zannat152-15-6048

Throw: System-generated exceptions are automatically thrown by the Java run-time system.

Throws: If a method is capable of causing an exception that it does not handle, it must specify this behavior so that callers of the method can guard themselves against that exception.

THROW AND THROWS

Identifies Error TypesSeparate error, handling codes from normal code

Clarifies the code and enhances readability

Makes clear and fault-tolerate program

ADVANTAGES

Exception handling can never be a disadvantage, you either need it or you don't in which case your application can crash.

DISADVANTAGES
