The sentence states that you will only get immutability if you use final fields correctly. That does not imply that final fields are necessary to achieve immutability. For at least one definition of "immutable" you can create classes with no setters and getters only returning immutable objects - without ever using the keyword "final". > I see how you might read that differently, but without final fields the > number of useful immutable classes is pretty small.
