public class MyFirstClass{ // this is the class name
public MyFirstClass() } // the constructor having the same name as class.
b. Constructors never have a return type not even void because it is only used to initialize the values of data members of the class when the object of the class is created so constructors are not directly called hence they do not need to have a return type.
c. Constructors are invoked using the new operator.
