In Java, there are three types of constructors:

1. Default Constructor: No-argument constructor provided by Java if no constructors are explicitly defined in a class.
2. Parameterized Constructor: Constructor with one or more parameters that allow you to initialize object properties during object creation.
3. Copy Constructor: A constructor that takes an object of the same class as a parameter and creates a copy of it. It’s not provided by default and needs to be defined explicitly if needed.

In Java, constructors can be divided into 3 types:

• No-Arg Constructor.
• Parameterized Constructor.
• Default Constructor.
