Java method().method().method(); How to do this?

Question

For example how do I do this?

getServer().getManager().registerNewUser(arguments);

and

getServer().getStats().user(arguments);

Stuff like this, I've tried searching the web but I cant find any tutorials on this,so I'm asking here.

The previous has to return an object on which you can call the next method, `getServer()` might return a `Server` instance, that has a `getManager()` methid — azro, Dec 23 '19 at 15:37

In OOP, in general, this concept is called class composition more on this you can find it here https://en.wikipedia.org/wiki/Object_composition

Also for java and the difference between Composition and inheritance https://www.baeldung.com/java-inheritance-composition

getServer() returns an object called server getStats() returns and obejct called Stats. he's probably asking about composition in OOP – Karim Dec 23 '19 at 20:26
