WebNov 10, 2024 · Java’s type constraints are a bug not a feature. They are there because Java does type erasure on generics, so Java can’t figure out how to call methods based on the value of type parameters alone. C++ on the other hand has no such restriction. Template parameter types can be any type compatible with the operations they are used with. WebA template is not a class or a function. A template is a “pattern” that the compiler uses to generate a family of classes or functions. In order for the compiler to generate the code, it must see both the template definition (not just declaration) and the specific types/whatever used to “fill in” the template. batteria pg1050
