在Java中,可以使用switch語句對枚舉進行遍歷,具體實現如下:
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");
}
}
}
}
通過在switch語句中對枚舉值進行判斷,可以實現對枚舉的遍歷。在上面的例子中,我們定義了一個Days枚舉,然后使用for循環遍歷所有枚舉值,并在switch語句中對每個枚舉值進行處理。這樣就可以實現對枚舉的遍歷。
