在Java中,可以使用switch语句对枚举进行遍历,具体实现如下:
public enum Days {
MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY;
}
public class Main {
public static void main(String[] args) {
for (Days day : Days.values()) {
switch (day) {
case MONDAY:
System.out.println("Monday");
break;
case TUESDAY:
System.out.println("Tuesday");
break;
case WEDNESDAY:
System.out.println("Wednesday");
break;
case THURSDAY:
System.out.println("Thursday");
break;
case FRIDAY:
System.out.println("Friday");
break;
case SATURDAY:
System.out.println("Saturday");
break;
case SUNDAY:
System.out.println("Sunday");
break;
default:
System.out.println("Unknown day");
}
}
}
}
通过在switch语句中对枚举值进行判断,可以实现对枚举的遍历。在上面的例子中,我们定义了一个Days枚举,然后使用for循环遍历所有枚举值,并在switch语句中对每个枚举值进行处理。这样就可以实现对枚举的遍历。
