Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.
Method cascading is much less common than method chaining – it is found only in a handful of object-oriented languages, while chaining is very common. A form of cascading can be implemented using chaining, but this restricts the interface; see comparison with method chaining, below.
An object-based language is a programming language that provides a construct to encapsulate state and behavior as an object. A language that also supports inheritance or subtyping is classified as object-oriented. [1] Even though object-oriented seems like a superset of object-based, they are used as mutually exclusive alternatives, rather than ...
The listed languages are designed with varying degrees of OOP support. Some are highly focused in OOP while others support multiple paradigms including OOP. [1] For example, C++ is a multi-paradigm language including OOP; [2] however, it is less object-oriented than other languages such as Python [3] and Ruby. [4]
Object-oriented languages extend the notion of type to incorporate data abstraction, highlighting the significance of restricting access to internal data through methods. [46] Eric S. Raymond has written that object-oriented programming languages tend to encourage thickly layered programs that destroy transparency. [47]
A common example is the iostream library in C++, which uses the << or >> operators for the message passing, sending multiple data to the same object and allowing "manipulators" for other method calls. Other early examples include the Garnet system (from 1988 in Lisp) and the Amulet system (from 1994 in C++) which used this style for object ...

Duck typing is similar to, but distinct from, structural typing.Structural typing is a static typing system that determines type compatibility and equivalence by a type's structure, whereas duck typing is dynamic and determines type compatibility by only that part of a type's structure that is accessed during runtime.
