In this lecture we will learn:
- Types of constructors in Java
- What are Parameterized constructors?
- What are default constructors?

A constructor in Java is a special method that is used to initialize objects.

Parameterized Constructor:-
- A constructor that takes some parameters is known as parameterized constructor.
- The parameterized constructor is used to provide different values to different objects.

Default Constructor:-
- A normal constructor is known as the default constructor.
- If you do not create any constructor, then java creates a default constructor. That constructor will be blank with no parameters.
- The default constructor is used to provide the default values to the object like 0, null, etc., depending on the type.

- The default constructor can change into the parameterized constructor. But Parameterized constructor can’t change into the default constructor.

When we print the obj1.setage() method, it is necessary to set the value inside the ().

Is the setAge method necessary after the constructor has been added?

Does creating a constructor, also creates a seperate Stack for it?
