Explanation:
- In the above example, it throws an exception that is throw 'e'.
- A throw exception accepts one parameter (in this case character 'e'), which is passed as an argument to the exception handler.
- Exception handler is declared with the catch keyword. It is mandatory to write catch block after the try block.
- Catch block is similar to regular function which always has at least one parameter and the type of the parameter is very important because, the type of the parameter/argument passed by the throw exception is checked against it, and only in the case they match, the exception is caught.
- Throw statement is executed when the handler matches its type with the argument which is specified in the statement.
