java - 无法获得实现扩展另一个接口(interface)以进行编译的接口(interface)的 Java 枚举

转载作者：行者123 更新时间：2023-11-29 06:38:20

我想创建一个实现 I2 的枚举，它扩展了 I1:

package a;

import static a.E1.E1A;
interface I1 extends I1 {}
interface I2 extends I1 {}
enum E1 implements I2 { E1A, A1B; }

class A {
    public static void main(String[] args) {
        switch (E1A) {
            case E1A:
                System.out.println("it worked!");
        }
    }
}

在我添加 I1 并使 I2 扩展 I1 之前它一直有效。现在它可以工作了，但找不到 E1A(以前有静电，所以这不是问题):

$ javac A.java
A.java:3: cannot find symbol
symbol  : static E1A
location: class a.E1
import static a.E1.E1A;
^
