A 'for' loop to iterate over an enum in Java

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 these
enum
values?

Answer

.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.
