What is constructor overloading give example?

So, In java program, if we create objects of the class with parameters then the respective overloaded constructor will be called . i.e. Employee e1 = new Employee(); //object e1 will call Employee()constructor. Employee e2 = new Employee(123); //object e2 will call Employee(int id)constructor.

Constructor Overloading in C++ In C++, We can have more than one constructor in a class with same name, as long as each has a different list of arguments . This concept is known as Constructor Overloading and is quite similar to function overloading.

Constructor overloading in Java is a technique of having more than one constructor with different parameter lists . They are arranged in a way that each constructor performs a different task. They are differentiated by the compiler by the number of parameters in the list and their types.

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 .

If we want to have different ways of initializing an object using different number of parameters , then we must do constructor overloading as we do method overloading when we want different definitions of a method based on different parameters.28 Haz 2021
