What Is The Existent Purpose Of Method Overloading Inward Coffee Or Programming?
Many programmers, including Java in addition to C++, knows most overloading e.g. method overloading or constituent overloading, but if you lot inquire them why you lot should overload a method? Many of them acquire clueless. This is a mutual work of one-half learning i.e. you lot know the concept but you lot don't know the application. If you lot neither know what work it solves nor what do goodness it provides, thence exactly knowing the concept is non expert enough. You won't endure able to reap all do goodness if you lot exactly know the concept in addition to never exercise it inward practice. The most of import do goodness overloading provides is a cleaner in addition to intuitive API.
It likewise gives you lot to a greater extent than flexibility spell writing API, for example, you lot tin laissez passer the sack aspect at the println() method. The undertaking of this method is to impress something in addition to add together a novel line. Now, you lot tin laissez passer the sack impress whatsoever variety of information type e.g. int, short, long, float, String or Object.
This is where overloading makes your undertaking easy, a println() is to impress in addition to method parameters volition pull what to print. If overloading was non available, you lot would halt upwards amongst clumsy APIs similar printString(), printObject(), printInteger() etc. So, method overloading provides you lot flexibility spell writing API.
Overloading likewise makes your API simpler, to laissez passer you lot an example, I'll selection the sort() method from C++ Standard Template Library (STL) i.e. std::sort function. The C++ is a groovy linguistic communication in addition to provides you lot the correct residual betwixt depression in addition to high-level language. It comes amongst a rich measure template library which provides mutual functionalities for application programming. STL is groovy but it has its ain fix of work e.g. old it acquire unnecessary verbose in addition to counter-intuitive.
The std:sort() sort elements inward a container inward place, for example, you lot hold off to sort elements of Vector equally shown below:
But, No, it won't piece of work similar that. The std::sort method would solely sort over a hit of elements inward a container, thence you lot must write:
Had they used overloading in addition to provided a sort() method, it would bring been much easier to exercise i.e. when you lot desire to sort all elements of Vector, you lot could bring used that. Here is a uncomplicated lawsuit of overloading which many programmers would bring appreciated in addition to mightiness bring done yesteryear themselves
So, Overloading tin laissez passer the sack brand your API a lot simpler to use. As an API designer, you lot must furnish cleanest API possible in addition to method overloading allows you lot to do that without duplicating code. You tin laissez passer the sack run into inward in a higher house example, the existent code is nevertheless inward master copy method but a wrapper approximately that makes the customer code much simpler. This is 1 expanse where Java actually beats C++. Java's API e.g. Collection framework is much meliorate to exercise than C++ Standard template library.
That's all most the real exercise of method overloading inward programming. It helps to furnish cleaner API. It likewise gives you lot flexibility spell designing API. Since method advert is crucial to dot intent, you lot tin laissez passer the sack exercise the same method until the purpose is same. By using overloading you lot tin laissez passer the sack exercise method arguments to furnish additional special e.g. sorting a listing or array or a container yesteryear overloading sort() method. Method overloading likewise prevents duplicate code yesteryear allowing you lot to leverage existing methods to twine around.

But, No, it won't piece of work similar that. The std::sort method would solely sort over a hit of elements inward a container, thence you lot must write:
std::sort(v.begin(), v.end());
