What is constructor overloading in computer?

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.

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 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
