System.out.println("--------------");
Direction3dd = Direction3.FRONT;
dd= Direction3.LEFT;
switch (dd) {
case FRONT:
System.out.println("你选择了前");
break;
case BEHIND:
System.out.println("你选择了后");
break;
case LEFT:
System.out.println("你选择了左");
break;
case RIGHT:
System.out.println("你选择了右");
break;
}
}
}
运行结果：
FRONT
前
前
--------------
你选择了左
