Accepted Answer

Exception handling is a mechanism to handle runtime errors and prevent program crashes.

Exceptions are thrown when an error occurs during program execution.
Try-catch blocks are used to handle exceptions and provide alternative code paths.
Finally blocks are used to execute code regardless of whether an exception was thrown or not.
Custom exceptions can be created to handle specific errors.
Examples of exceptions include NullPointerException, ArrayIndexOutOfBoundsException, and IOException.
