I have an enum
in Java for the cardinal & intermediate directions:
public enum Direction {
NORTH,
NORTHEAST,
EAST,
SOUTHEAST,
SOUTH,
SOUTHWEST,
WEST,
NORTHWEST
}
How can I write a
for
loop that iterates through each of theseenum
values?
.values()
You can call the values()
method on your enum.
for (Direction dir : Direction.values()) {
// do what you want
}
This values()
method is implicitly declared by the compiler. So it is not listed on Enum
doc.
