Explain constructors.
What will be an ideal response?
A method that has the same name as a class and that establishes an object is a constructor method, or more simply, a constructor. Constructors fall into two broad categories:A default constructor is one that requires no arguments.A non-default constructor or a parameterized constructor requires arguments.All non-default constructors are written by a programmer, but there are two categories of default constructors:An automatically-created default constructor exists in a class in which the programmer has not explicitly written any constructors.A programmer-written default constructor can reside in any class and replaces the automatically-created one.In object-oriented programming (OOP) languages, you can write both default and nondefault constructors for a class; if so, the constructors are overloaded.
