Object-Oriented Terminology a class describes the contents of the objects that belong to it: it describes an aggregate of data fields (called instance variables), and defines the operations (called methods). object: an object is an element (or instance) of a class; objects have the behaviors of their class.

  • What are classes in oops?

    In object-oriented programming, a class is a template definition of the methods and variables in a particular kind of object.
    Thus, an object is a specific instance of a class; it contains real values instead of variables.
    The class is one of the defining ideas of object-oriented programming.

  • What are objects and object classes?

    A class defines object properties including a valid range of values, and a default value.
    A class also describes object behavior. An object is a member or an "instance" of a class.
    An object has a state in which all of its properties have values that you either explicitly define or that are defined by default settings.

  • What is the method in object class?

    A class in Java is a set of objects which shares common characteristics/ behavior and common properties/ attributes.
    It is a user-defined blueprint or prototype from which objects are created.
    For example, Student is a class while a particular student named Ravi is an object.22 sept. 2023
