Inject Util Class with Google Guice vs static Methods?

http://stackoverflow.com/questions/4370683/inject-util-class-with-google-guice-vs-static-methods

It depends on the nature of your convert() method.

If it's something

• simple
• deterministic (i.e. doesn't depend on additional parameters)
• have no side effects
• is unlikely to change
• etc

you can keep it as a static utility method.

Otherwise it's a good candidate for dependecy injection (you can rename it to ConversionService to make it more clear).
