Why Java Lacks the const Keyword: An In-Depth Analysis from final to Constant Semantics
This article explores why Java does not include a const keyword similar to C++, instead using final for constant declarations. It analyzes the multiple semantics of const in C++ (e.g., const-correctness, read-only references) and contrasts them with the limitations of Java's final keyword.
