With primitives, == is fine. WIth objects, == is supposed to check that the memory location is the same memory location (literally the same object). It may work with strings (due to a behind the scenes optimization), but object equality should usually be .equals, though you may want to confirm that the object provides an equals method to override the equals method defined on the object class.
