- - - - Strength of the code
        
        The memory is not managed by the user but from compiler that accesses to the memory cells and decides where to put the variables.
        This limits the risk of crash of your computer, because the instruction can't contain the address of data stored elsewhere.
  - - - Consists int the methods in the same class that they have same names but different signatures
    - - Consists in Inheriting methods with different implementation for the subclasses
- - - - Abstract class
        
        Is a class with at least one method without implementation because it is too generic
        
        It can be recognised because it has the word "abstract" in the signature
      - Concrete class
        
        It is a class with all methods implemented
        
        You can create an object in this class
      - Interface class
        
        Is a class without implementations
        
        Represents a contract with the programmer
    - - Methods
        
        Are the actions that the objects can take.
        Every method causes a change in the object behaviour.
      - Attributes
        
        Are the characteristics of the objects
