Select among many options with switch (classic and enhanced switch).

Repeat work with for, while, and do-while loops.

Use classic for loops and enhanced for-each loops over arrays/collections.

Repeat while a condition remains true.

Run a loop body at least once with do-while.

Exit loops early with break or skip an iteration with continue.

Store fixed-size sequences of values in arrays.
