== Why is this an issue?
|
|
|
|
There is no good reason to declare a field "public" and "static" without also declaring it "const". Most of the time this is a kludge to share a state among several objects. But with this approach, any object can do whatever it wants with the shared state, such as setting it to ``++null++``.
