CHAPTER 19 — Result-controlled Loops

A third kind of loop can be built from the fundamental control statements in Java. This is the result-controlled loop. (Other names for it are free loop and general loop).

A result-controlled loop keeps looping until the computation has reached a particular goal, without knowing exactly how long that might take. It is like the instruction in a cookie recipe that says "keep stirring until the ingredients are thoroughly blended." You quit stirring only when the desired goal has been achieved.
