Why are the values HERE, EAST, and AHEAD (among others) written in
all uppercase?
They are constant values and constant values are
usually written in all uppercase in Java.
- All variable names in Java should be written in all uppercase.
- It is a mistake that someone was too lazy to fix.
- They are important values and important values are usually
written in all uppercase in Java.
Do distinguish constants (where the value never changes) from
variables (where the value may change over time), Java programmers
use a capitalization convention to distinguish the names of constants.
