定义

public enum OrderStatus {

    CODE(1,"代码"),
    LIFE(2,"生命"),
    SPRING(3,"春天");

    int id;
    String name;

    OrderStatus() {
    }

    OrderStatus(int code, String name) {
        this.id = code;
        this.name = name;
    }

    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }
}

调用

public class Order {
    public static void main(String[] args) {
        OrderStatus.CODE.getName();
        OrderStatus.LIFE.getId();
        System.out.println("This is my"+OrderStatus.CODE);
        System.out.println("这是我的"+OrderStatus.CODE.getName());
    }
}
