Why is there no Constant feature in Java?

Question

I was trying to identify the reason behind constants in Java I have learned that Java allows us to declare constants by using final keyword.

My question

Answer 1

The C++ semantics of const are very different from Java final. If the designers had used const it would have been unnecessarily confusing.

The fact that const is a reserved word suggests that the designers had ideas for implementing const, but they have since decided against it; see this closed bug. The stated reasons include that adding support for C++ style const would cause compatibility problems.
