Why Java Generics Are Bad at Edward Stafford blog

Why Java Generics Are Bad. One limitation of java generics is that generic type parameters are erased so there's no way that you can reflect on the type. When you create a generic class in. In c++, assuming the compiler given enough time and memory, templates can be used to do anything and everything that can be done. The main problem is that java doesn't actually have generics at runtime. Without any further type bound, t will be treated as object if you want to call any method on the field or argument value. It's a compile time feature. The main reason to use generics is type safety. Java style generics force a level or pointer indirection which has some cost on its own but more importantly means you can't control data. Many things done just in case lead to things like bloat and performance issues that people will complain about with just as much irrational. In our previous examples, we haven't specified a type, resulting in the list being a list of object s.
