ABSTRACTION: The main purpose of abstraction as the name implies to hide unnecessary data which helps to reduce the complexity of a program and only display needed information.

We can only write a java program with the aid of these 3 elements, without class and interface, there is no Java program.

There are 4 types of access modifiers; Public Private  protected  Default We cannot declare a Java class as private, or protected, the same goes for interface and enum. Examples of the basic element's syntax:      The example in the fi...
