What is Exception in Java?

Exception is an error event that can happen during the execution of a program and disrupts its normal flow. Exception can arise from different kind of situations such as wrong data entered by user, hardware failure, network connection failure etc.
Whenever any error occurs while executing a java statement, an exception object is created and then JRE tries to find exception handler to handle the exception. If suitable exception handler is found then the exception object is passed to the handler code to process the exception, known as catching the exception. If no handler is found then application throws the exception to runtime environment and JRE terminates the program.
Java Exception handling framework is used to handle runtime errors only, compile time errors are not handled by exception handling framework.
