Comment

In Kotlin, you can create a custom exception by defining a new class that inherits from the Exception class or one of its subclasses. For example, you can create a custom exception called InvalidInputException as follows:

class InvalidInputException(message: String): Exception(message)

You can then throw this exception wherever you need to in your code, using the throw keyword:

fun checkInput(input: String) {
    if (input.isEmpty()) {
        throw InvalidInputException("Input cannot be empty")
    }
    // continue processing input
}
