Exception Types and Their Hierarchy

Exception types

A few types of exceptions are defined in Kotlin that we use in certain situations. Some of the most important ones are:

• IllegalArgumentException: We use this when an argument has an incorrect value. For example, when we expect our argument value to be bigger than zero but it is not.

• IllegalStateException: We use this when the state of our system is incorrect. This means the values of properties are not accepted by a function call.
