for loop to interate over enum in Java?

Question

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 1

Enum#values():

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

Answer 2

you can do the following:

for (Direction dir : Direction.values()) {
  // do what you want
}

Answer 3

You can do this as follows:

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

Answer 4

If you don't care about the order this should work:

Set<Direction> directions = EnumSet.allOf(Direction.class);
for(Direction direction : directions) {
    // do stuff
}

Answer 5

for(Direction dir : Direction.values())
{

}

Answer 6

    for (Direction  d : Direction.values()) {
       //your code here   
    }
