Answer:
1. When an object of the class is passed (to a function) by value as an argument.
2. When an object is constructed based on another object of the same class.
3. When compiler generates a temporary object.
Explanation:
A constructor exists just a special type of subroutine that instantiates an object from the class.
<h3>What is constructor?</h3>
A constructor exists as a special kind of subroutine in a class. It maintains the same name as the name of the class, and it has no return type, not even void. A constructor exists called with the new operator in order to create a new object.
A constructor exists as a special process of a class or structure in object-oriented programming that initializes a newly constructed object of that type. Whenever an object exists created, the constructor is called automatically. A constructor in Java exists as a special method that is utilized to initialize objects. The constructor exists called when an object of a class is created.
A subroutine exists as a sequence of program instructions that serves a specific task, packaged as a unit. This unit can then be utilized in programs wherever that separate task should be performed.
Hence, A constructor exists just a special type of subroutine that instantiates an object from the class.
