I like the reference, and note that this pattern is also repeated
in the newer java.util.Map interface.
NoSuch*Exception is more typical of an iteration, where *not*
throwing an exception would lead to infinite loops.
Note: Both the 'Map' and 'Iterator' interfaces contain
existence-test methods: 'containsKey' and 'hasNext'.
