_29_Exception_Handling.java

// an exception is unexpected , unwanted & abnormal situation that occured at runtime called exception.
// Ex - 1- powercutException, 2- filenotfoundException, 3- illException etc.
// we should have an alternate source through which we can handle the exception.
// following techniques to work with exception:- 1- try, 2- catch, 3- throw, 4- throws, 5- finally.
// predefined code then use try and catch.
// userdefined then throws and throws.
// we handle exception because normal flow of the program is maintained.
