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. Try and catch block: Java virtual machine (JVM) searches to handle the error in “catch” clause at that time of exception in the program. So “try-catch” statements are used in order to handle those exceptions. The following are the main keywords used in exception handling. “try” block: Try block contains the block of statements to monitor the exception and it thrown the exception. “catch” block: Catch block catch exception thrown by the try block to handle it.
