"Фича" имхо не функция, а часть языка. "То есть дженерики, которые сами по себе являются мощными элементами языка, также позволяют значительно улучшить и уже существующие его части".hoz пишет: ↑14 фев 2019, 15:30 Perhaps the one feature of Java that has been most significantly affected
by generics is the Collections Framework. The Collections Framework is
part of the Java API and is described in detail in Chapter 19, but a brief
mention is useful now. A collection is a group of objects. The Collections
Framework defines several classes, such as lists and maps, that manage
collections. The collection classes have always been able to work with any
type of object. The benefit that generics added is that the collection classes
can now be used with complete type safety. Thus, in addition to being a
powerful language element on its own, generics also enabled an existing
feature to be substantially improved.
