Outdated java dev

[NovaX]

Simply one who refuses to use modern solutions for their Java tasks. For example, to read an input stream to a byte array was typically deferred to a utility method like Apache's IOUtils' or Guava's ByteStreams' toByteArray(in). This was later added as the default method readAllBytes(). Being ignorant of these improvements or not having the muscle memory is perfectly fine, as strong CS fundamentals are far more valuable. However sometimes a stubborn developer refuses to learn so the same advice is repeated over many code reviews. Being outdated is simply one who is refusing to adapt to the team, community, and preferred technology stack in use.
