An object in java is a runtime entity of a java class. It has two characteristics 1. State (variables) and 2. Behavior (methods). It has below benefits
1. Encapsulation (Data hiding): It hides data and internal implementation from other objects.
2. Modularity (task modulation): It contains a set of activities for a specific task of an application.
3. Reusability: It facilitates reusability of functionality through inheritance.
4. Easy maintenance: It enhance the readability and understandability of an application. It also helps the developer to trace bugs in an application.
