+# Java Tutorial: Introduction to Object Oriented Programming
+- Object-Oriented Programming tries to map code instructions with real-world, making the code short and easier to understand.
+- With the help of OOPs, we try to implement real-world entities such as object, inheritance, abstraction, etc.
+- OOPs helps us to follow the DRY(Don't Repeat Yourself) approach of programming, which in turn increases the reusability of the code.
+
+### Two most important aspects of OOPs - Classes & Objects :
+
+#### Class :
+- A class is a blueprint for creating objects.
+- Classes do not consume any space in the memory.
+- Objects inherit methods and variables from the class.
+- It is a logical component.

+
+#### Objects :
+- An object is an instantiation of a class. When a class is defined, a template (info) is defined.
+- Every object has some address, and it occupies some space in the memory.
+- It is a physical entity.
+- Take a look at the below example to get a better understanding of objects and classes :

+
+### How to model a problem in OOPs
+- We identify the following:
+
+```
+Noun              - Class                        - Employee
+Adjective         - Attributes                   - name, age, salary
+Verb              - Methods                      - getSalary(), increment()
+```
+
+- This is all for this tutorial. We will do a detailed discussion on every aspect of OOPs in further tutorials.
