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

`.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.

java loops for-loop enums

All the constants of an enum type can be obtained by calling the implicit public static T[] values() method of that type:

 for (Direction d : Direction.values()) {     System.out.println(d); }

java loops for-loop enums

You can do this as follows:

for (Direction direction : EnumSet.allOf(Direction.class)) {  // do stuff}
