Just as a heads up to anyone taking the exam: while the Sun exams, and the exam linked to here, show the UML for an interface as a circle, on the actual SCJA exam, interfaces will be denoted with an italicized name, and a closed headed arrow with a dotted line, pointed towards it.

Not entirely true. The actual exam does have questions that use the new lollipop notation as well as the italics notation.
