Java Encapsulation & Inheritance Revision | Java for Beginners in Nepali

Encapsulation:

Bundling code into individual software objects provides a number of benefits, including:
Modularity: The source code for an object can be written and maintained independently of the source code for other objects. Once created, an object can be easily passed around inside the system.

Information-hiding: By interacting only with an object's methods, the details of its internal implementation remain hidden from the outside world.

Code re-use: If an object already exists (perhaps written by another software developer), you can use that object in your program. This allows specialists to implement/test/debug complex, task-specific objects, which you can then trust to run in your own code.

Plug ability and debugging ease: If a particular object turns out to be problematic, you can simply remove it from your application and plug in a different object as its replacement. This is analogous to fixing mechanical problems in the real world. If a bolt breaks, you replace it, not the entire machine.

Inheritance:

Inheritance in java is a mechanism in which child object acquires all the properties and behaviors of parent object.
