In fact, what are the different types of constructor?
Types of Constructor Java No-Arg Constructors Similar to methods, a Java constructor may or may not have any parameters (arguments). ...

A Constructor with arguments (or you can say parameters) is known as Parameterized constructor. As we discussed in the Java Constructor tutorial that a constructor is a special type of method that initializes the newly created object.
Keeping this in consideration, is constructor generated default constructor?
In computer programming languages, the term default constructor can refer to a constructor that is automatically generated by the compiler in the absence of any programmer-defined constructors (e.g. in Java), and is usually a nullary constructor. In other languages (e.g. in C++) it is a constructor that can be called without having to provide any arguments, irrespective of whether the constructor is auto-generated or user-defined.

When is a copy constructor an eligible constructor?

A copy constructor is eligible if it is not deleted. no copy constructor with the same first parameter type is more constrained than it. Triviality of eligible copy constructors determines whether the class is an implicit-lifetime type, and whether the class is a trivially copyable type .

How does a factory constructor invoke a constructor?
