Runtime polymorphism occurs when an object is associated with functionality during runtime. Method overriding can be used to provide runtime polymorphism. The Java virtual machine selects the method to invoke during runtime, not at compile time. It’s also known as dynamic and late binding....
Method overloading is often referred to as compile polymorphism, whereas method overriding is runtime polymorphism. The difference is in when the actual code to execute is resolved - at compile time or runtime. Comparing them against each other doesn't make much sense, though, as they solve ...
For example, static data in aCprogram is allocated at compile time whereas non-static data is allocated atrun time, probably on thestack. This article is provided by FOLDOC - Free Online Dictionary of Computing (foldoc.org) The time it takes to translate a program from source language into ...
The compile-time type of "o" is Object, and its runtime type will be String. The compile-time type governs which methods can be called, while the runtime type governs what happens during the actual call. You can write ? 1 int i = o.hashCode(); because Object has a hashCode method...

Open polymorphism is a powerful mechanism that is tied to the runtime by its nature, so giving up on compile-time errors is a tradeoff for convenience. That's a fine tradeoff if some people want to be able to make it, but as I've shown in my example above, it is not a nescesar...
The world of object-oriented programming revolves around *explicit it * interfaces andruntimepolymorphism. For example, class Widget{public:Widget();virtual~Widget();virtual size_tsize()const;virtualvoidnormalize();voidswap(Widget&other);...}; ...
Due to exhaustive matching DUs provide an alternative to polymorphism when you want to have a method with guaranteed behaviour-per-type (i.e. adding an abstract method on a base type, and then implementing that method in each type). It's a really powerful tool, ask any f#/Scala dev! :...
