What is a method and properties in OOP?

What is a method in OOP?
A method in object-oriented programming (OOP) is a procedure associated with a message and an object. This allows the sending objects to invoke behaviors and to delegate the implementation of those behaviors to the receiving object. A method in Java programming sets the behavior of a class object.
What is a class in OOPs?
In object-oriented programming, a class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods). The class is a blueprint that defines a nature of a future object.
What are property methods?
