Java uses polymorphism when a variable of type Shape can refer to a Circle or a Rectangle and call the correct draw method.
A Java polimorfizmust használ, amikor egy Shape típusú változó Circle-re vagy Rectangle-re hivatkozhat, és a megfelelő draw metódust hívja meg.
The library relies on polymorphism so that the same function can process several data types.
A könyvtár a polimorfizmusra támaszkodik, így ugyanaz a függvény többféle adattípust tud feldolgozni.

Apibrėžimas
In programming, polymorphism lets one command, method, or interface work with different kinds of objects or data.
A feature of a programming language or design that allows the same interface, operation, or function name to work with values or objects of different types, often with behavior chosen according to the actual type.
