What is the difference between == and .equals() in Scala, and when to use which?

Is the implementation the same as in Java?

There is a similar question (Why == operator and equals() behave differently for values of AnyVal in Scala), but that is specific to AnyVal. This question is concerned with the more general case of Any.

You normally use ==, it routes to equals, except that it treats nulls properly. Reference equality (rarely used) is eq.
