The significance of compile-time polymorphism and run-time polymorphism is explained briefly. We also discuss about the relationship between operator overloading, function overloading and virtual function. We also present the design patterns with an example which helps us to ...
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 ...
when the program is being executed. As well as the work done by thecompiler, this may include macro preprocessing as done bycppfor example. The final stage of program construction, performed by thelinker, would generally also be classed as compile time but might be distinguished as link time...

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...
This paper describes a system for both predicting and checking the types of Common Lisp programs at compile-time. The system is capable of deriving type declarations from constraints implicit in the code and identifying potential run-time type errors. These capabilities can be used to improve the...
