Are composition and inheritance the same? That is, the declaration of the base class (struct) inside the derived class, and cast the derived as a base: So if you have a person class, then you have a student class that extends person, student inherits all the things that person.
In The Inheritance Chapter, It Explains That Inheritance Of Members Is Closely Tied To Their Declared Accessibility.
So inheritance and abstract class is same regardless of abstract keyword so we can implement abstract class using inheritance, here just method signature change classes (that's my. There is no multiple inheritance in java. If i want to implement the composition pattern, how can i do that in java?

Inheritance is when a 'class' derives from an existing 'class'. If the inheritance is public, everything that is aware of base and child is also aware that child inherits from base. When should i choose inheritance instead of composition?
That Is, The Declaration Of The Base Class (Struct) Inside The Derived Class, And Cast The Derived As A Base:
One strong point of inheritance is that we can use the code of base class in. I'm trying to wrap a c++ class using swig that involves multiple inheritance and another class with a method returning a shared pointer to a class declared as an interface in swig. If a superclass member is accessible by its simple name in the subclass.

Why prefer composition instead of inheritance? So if you have a person class, then you have a student class that extends person, student inherits all the things that person. Yes, you can emulate inheritance in c using the type punning technique.
Interfaces Can Be Used To Achieve Multiple Inheritance In Java.
