Scala is stack-compatible with Java. You can call any Java function from Scala and vice versa. Additionally, for ease of migration, any valid Java class is a valid Scala class. The Scala standard library includes the Java standard library copy-pasted in. For the sentence "Scala is compatible with Java", there is almost no interpretation of "compatible" that would make the sentence untrue.
