difference between setValue and push method

Question

Can someone please help me elaborate difference between setValue() and push() methods in Firebase? Thanks in Advance.

@RaajNadar Nope thats not a duplicate. This question is about the difference between push() and set() and you duplicate is about update() and set(). — André Kool, Apr 16 '18 at 14:03

SetValue() is to write or replace data in a defined path. Example : I want to set the username for a given user :

Firebase.getInstance().getReference().child("user").child("username").setValue("Jhon Doe");

SetValue() can also be used to delete data in a defined path by calling it without parameters:

Firebase.getInstance().getReference().child("user").child("username").setValue();

Push(), is used to add a new node. So, every time this method is called, firebase will automatically generate a new unique ID. Calling Push() without parameters won't actually create any data in the database but only generate the unique ID (on the client side).
