Question

Java

Explain in a simple way the topic of using objects as parameters using simple examples + what is it for?

Answer 1

explanation with a simple example
In short, if you have methods that take several parameters as input, and some kind of validation is needed for the parameters, then it is more convenient to create a class that encapsulates all this goodness in itself, and the methods will accept an instance of this class and take values ​​from there without worrying about their validity.
