Conventional wisdom says that literal values in code are bad and should be replaced with constant fields. The usual justification is that when you need to change the value it is easier to change the value of the constant than to change the literal in the various places where it appears. This avoids the real issue: why is the value appearing in multiple places?

Constants are a deodorant. Rather than using a literal value in numerous places, which is bad, we empower ourselves to reference a static field in numerous places, which is almost exactly as bad. Perhaps instead we should consider what concept that value represents that needs to be reused all over our code and find a way to encapsulate that responsibility.
