Exception: It is nothing but an undesirable or unexpected event that occurs at run time which interrupts the normal flow of the program ’s commands. Exception handling is a mechanism that handle runtime errors like “ClassNotFoundException”, “SQLException”, and so on. An advantage of exception handling is to maintain a flow of the program. An exception can be handled using “try” and “catch” block. Types of exceptions: There are two types of exceptions. They are: Checked Exception: A class that inherits a “Throwable” class except “RunTimeException” and “Error” are called as checked exceptions. Example: “IOException” Unchecked Exception: A class that inherits a “RunTimeException” class is called as unchecked exceptions. Example: “ArrayIndexOutOfBoundException” “throws” clause: This clause is used to declare the exception. This provides information to the programmer that the program might produce an exception so it is better to give the exception handling code which maintains the normal flow of the program. It is usually given in the method header. Syntax: Method_Name throws ExceptionName { //statements }
