关于java：Enumerations，增强了for循环

Enumerations, enhanced for loop

本问题已经有最佳答案，请猛点这里访问。

假设我有enum值：

1
2
3
4

public enum Day {
SUNDAY, MONDAY, TUESDAY, WEDNESDAY,
THURSDAY, FRIDAY, SATURDAY
}

使用增强的for循环结构，我如何编写一个代码片段来打印一周中的所有时间。我刚开始对循环进行增强，所以不知道从哪里开始。

增强的for循环构造

The enhanced for-loop is a popular feature introduced with the Java SE
platform in version 5.0. Its simple structure allows one to simplify
code by presenting for-loops that visit each element of an
array/collection without explicitly expressing how one goes from
element to element.

1
2
3
4

for(Day days: Day.values()){

System.out.println(days); // printing days
}

你能做的是：

1
2
3

for (Day day : Day.values()) {
System.out.println(day);
}

这是使用for循环迭代所有枚举常量的方法。

1
2
3
4
5
6

for (Day day : Day.values()) {

//your code
//Use variable"day" to access each enum constant in the loop.

}
