Attributes and methods are both characteristics that an object can have. Attributes are the data variables that store information about the object, while methods are the functions that can be performed by the object.

A library is a collection of precompiled code and resources that can be used by other programs. An object can use a library to access additional functionality or resources.

An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate and interact with each other. An object can use an API to interact with external systems or services.

Overall, an object can have attributes and methods, and it can also use a library or an API to enhance its functionality.
