+# Interface
+* Interface is basically a replacement for for extending classes since we can implement as many interfaces as we want in a Class. 
+* Interface basically has two main components
+    - Constants (By default)
+    - Methods (They do not have data type)
+* When we implement the **Interface** to a class then we nedd to define all the **methods** of the Interface.
+
+# Abstract
+* Abstract is similar to Interface. It is a class itself. 
+* When we extend an Abstract Class to a Class, we need to define all the **methods** defined in the Abstract Class else the derived class again should be Abstract.
