An object is defined as the thing or an entity or event which is related within the context of the problem in the design phase.	An object is defined as the instance of class in implementation phase.
It relates within the situation of the problem.	The interactions of the objects in the program simulate the interaction of the objects in the real world problem.
Example: //class definition public class Test { //class variables Name a; String s; //class method definition public Show() { //statement } }; Here, the class name is “Test”...
