| Question ID 21426 | Given:
public enum Direction {
NORTH, EAST, SOUTH, WEST
}
Which statement will iterate through Direction?
|
| Option A | for (Direction d : Direction.values()){
//
}
|
| Option B | for (Direction d : Direction.asList()){
//
}
|
| Option C | for (Direction d : Direction.iterator()){
//
}
|
| Option D | for (Direction d : Direction.asArray()){
//
}
|
| Correct Answer | A |
Explanation Explanation: The static values() method of an enum type returns an array of the enum values. The foreach loop is a good way to go over all of them. //... Loop over all values. for (Direction d : Direction.values()){ System.out.println(d); // PrintsNORTH, EAST, ... }
