What is constructor

Constructors have the same name as the class or struct, and they usually initialize the data members of the new object. In the following example, a class named Taxi is defined by using a simple constructor . This class is then instantiated with the new operator.

In Java, two or more methods may have the same name if they differ in parameters (different number of parameters, different types of parameters, or both) . These methods are called overloaded methods and this feature is called method overloading. For example: void func() { … }

The technique of having two (or more) constructors in a class is known as constructor overloading. A class can have multiple constructors that differ in the number and/or type of their parameters.

Constructor overloading is a concept of having more than one constructor with different parameters list, in such a way so that each constructor performs a different task . For e.g. Vector class has 4 types of constructors.
