Program Plan Intro

Exception:

An exception is a problem that creates during the execution of a program; it offers a method to transfer control from one part to another part of a program.

An exception handling is created by using the following three keywords such as try, catch and throw.

• The “try” block have the program for the basic algorithm that says the computer what to do when all goes well.
• The “throw” keyword throws an error statement to the “catch” block.
• The “catch” block will catch the exception or handling the exception.

Generally, the compiler executes “try” block. In the “try” block, if the statements cause an exception, it throws an error statement to the “catch” block using the keyword “throw”. The “catch” block then handles the error based upon the type of exception.
