一个'for'循环迭代Java中的枚举

问题：

I have an enum in Java for the cardinal & intermediate directions: 我有一个Java的enum主要和中间方向：

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? 如何编写迭代这些enum值的for循环？
