Discuss exception handling.

What will be an ideal response?

Object-oriented programs employ a group of techniques for handling errors called exception handling. The generic name used for errors in object-oriented languages is exceptions because errors are not usual occurrences; they are the "exceptions" to the rule.

In object-oriented terminology, you try some code that might throw an exception. If an exception is thrown, it is passed to a block of code that can catch the exception, which means to receive it in a way similar to how a parameter is received by a method.
