Class Constants

  • public final class Constants
extends Object
    This class is used for global constants only.

    If your constant is only to be used in a single package, put it in a Constants-class in that package, and make sure it is package private (no modifiers).

    If your constant is used in a single class only, put it in that class, and make sure it is private.

    Remember everything placed here MUST be constants.

    This class is never instantiated, so thread security is not an issue.
