+            Java adds an additional, if seldom used variation of the <c>while</c> loop called the <c>do-while</c> loop.
             The <c>do-while</c> loop is very similar to <c>while</c> except that the condition is evaluated at the end of the loop rather than the beginning.
             This ensures that a loop will be executed at least one time.
             Some programmers prefer this loop in some situations because it avoids an additional assignment prior to the loop.
