I am not sure what you are asking here. There was a version of CodeWarrior for Java development, but that was sold off years ago. It is no longer available.
The Classic IDE versions of CodeWarrior does not require Java to run. However, the newest Eclipse-based version of CodeWarrior does. The Eclipse-based CodeWarrior download does not provide a Jave run-time (JRE). You will have to get that from Oracle's Java download page.
