* Properties or behaviours of the Animals class are name, height ,color, etc
* And methods r the actions done by the animals like eating, walking, etc.

Answer 2

When you create a class they should use the Single Responsibility Principle so they should only handle one thing e.g the Animal class. You also have encapsulation which is a method of hiding variable and methods using the 'private' keyword so they cannot be modified outside the class. Another term you may hear is polymorphism which allows a single interface but many implementations using method overloading and overriding.
