Java OOP

    

        OOP sands for Object-Oriented Programming 

 

Procedural Programming -: Writing procedures or methods that performs operations on data.

Object-Oriented Programming -: Creating objects that contains both data & methods

Advantages of object-oriented programming over procedural programming -:

• faster & easier to execute
• provide the clear structure for the programs
• keep DRY "Don't repeat yourself" principle, and makes the code easier to maintain, modify & debug.
• possible to create less reusable application with less code & shorter development time

 

Classes & Objects 

Classes and objects are the two main aspects of object-oriented programming. 

Look following examples to get idea about classes & objects -:

ex 1-:

class - fruit

objects -: Apple, Banana, Mango

ex2-:

class-: Animal

objects -: Dog, Cat, Monkey

class is a template for object. object is an instance of a class.

When the individual objects are created, they inherit all the variables and methods from the class.
