The sole purpose of the constructor is to initialize the data fields of objects in the class . Java constructor can perform any action but specially designed to perform initializing actions, such as initializing the instance variables. A constructor within a class allows constructing the object of the class at runtime.

There are two types of constructors in Java: no-arg constructor, and parameterized constructor . Note: It is called constructor because it constructs the values at the time of object creation. It is not necessary to write a constructor for a class.

Read moreWhat is C# constructor?
A constructor in C# is a member of a class . It is a method in the class which gets executed when a class object is created. Usually we put the initialization code in the constructor. The name of the constructor is always is the same name as the class. A C# constructor can be public or private.
Read moreHow do I call a parameterized constructor from another class in C#?
To call one constructor from another within the same class (for the same object instance), C# uses a colon followed by the this keyword, followed by the parameter list on the callee constructor’s declaration . In this case, the constructor that takes all three parameters calls the constructor that takes two parameters.
Read moreHow do you call a parameterized constructor?
In the above example, when parameterized constructor in invoked, it first calls the default constructor with the help of this() keyword . The default constructor initializes “member” variable to “YES” and then continues to execute parameterized constructor.
Read moreWhy have an empty constructor C#?
If you declare an empty constructor, the C# compiler will not dynamically generate a parameter-less constructor . If you do not use an access modifier with the constructor, it will also become a private constructor by default. Using the private keywords makes it obvious for developers by explicitly stating the type.
