Definition of Exception Handling:
An exception handler is a piece of code that specifies what a program should do when an unexpected event interrupts the normal flow of its instructions. In the context of computers, an exception is an unanticipated event that occurs during the execution of a program and disturbs the flow of its commands.
There are two sorts of exceptions in Java:
Programs connect with the operating system and other software systems through multiple levels. When a checked exception occurs, the procedure that caused it creates this exception object that contains information such as the type of exception and the state of the program at the time of the occurrence.
Throwing an exception refers to the creation and subsequent passing of this item. The method sends the object to the runtime system, which examines the exception handler code levels that satisfy the exception object’s specifications. The exception handler is said to catch an exception in this scenario.
The operating system creates a fatal exception message if an adequate exception handler cannot be identified, which implies the program must close and maybe the computer as well.
