在Java中迭代枚舉值

The Enum class is the common base class of all Java language enumeration types.

Example

Let us see an example to iterate over enum values using for loop −

public class Demo {
   public enum Vehicle { CAR, BUS, BIKE }
   public static void main(String[] args) {
      for (Vehicle v : Vehicle.values())
         System.out.println(v);
   }
}

輸出

CAR
BUS
BIKE

Example

現在讓我們看另一個例子，使用for each循環迭代枚舉值：

import java.util.stream.Stream;
public class Demo {
   public enum Work { TABLE, CHAIR, NOTEPAD, PEN, LAPTOP }
   public static void main(String[] args) {
      Stream.of(Work.values()).forEach(System.out::println);
   }
}

輸出

TABLE
CHAIR
NOTEPAD
PEN
LAPTOP
