Encapsulation, Inheritance, Polymorphism, Abstraction are the four pillars of OOPS in Java.
Encapsulation: Bundling data and methods that operate on the data into a single unit.
Inheritance: Allows a class to inherit properties and behavior from another class.
Polymorphism: Ability to present the same interface for different data types.
Abstraction: Hiding the implementation details and showing only the necessary features.

They do not have a return type, not even void.
Constructors are called when an object of a class is created.
Example: public class Car { public Car() { // constructor code } }
