Java class: In java, the classes are the abstraction of real world entity. The classes are abstract because it doesn’t give a shape/form. The class is a structural definition or a blueprint of design upon the objects are constructed. The objects are representations of the designs. The java classes contain attributes and methods. These are known as the class members. Theses class members are accessible only for the objects of that class. For example, if there is a class “Rectangle”, then the attributes of the class can be “height”, “width” and the methods can be “findHeight()” and “findWidth()”. An object of the class “Rectangle” can be created to access the attributes and methods of it.
