What is the Use of Method Overloading in Java and Object Oriented Programming? [Answer]

Many programmers, including Java and C++ developer, knows about the overloading concept like method overloading or function overloading, but if you ask them why you should overload a method? Many of them become clueless. This is a common problem of half learning i.e. you know the concept but you don't know the application. If you neither know what problem it solves nor what benefit it provides, then just knowing the concept is not good enough. You won't be able to reap all benefits if you just know the concept and never use it in practice. The most important benefit overloading provides is a cleaner and intuitive API.

Difference between Method Overloading and Overriding in Java?

Method Overloading vs Method Overriding
Though the name of the method remains the same in the case of both method overloading and overriding, the main difference comes from the fact that method overloading is resolved during compile time, while method overriding is resolved at runtime. Also, rules of overriding or overloading a method are different in Java. For example, a private, static and final method cannot be overridden in Java but you can still overload them. For overriding both name and signature of the method must remain the same, but for the overloading method, the signature must be different. Last but not least difference between them is that call to overloaded methods are resolved using static binding while the call to an overridden method is resolved using dynamic binding in Java.
