Java:如何在其类型定义中修改当前枚举的值？

public interface CustomEnum {
    void setValue(String value);
    String getValue();
}

public enum MyEnum implements CustomEnum {
    VALUE1, VALUE2;

    private String value;

    @Override
    public void setValue(String value) {
        this.value = value;
    }

    @Override
    public String getValue() {
        return value;
    }
}

import java.lang.reflect.Field;

public enum MyEnum {
    VALUE1, VALUE2;

    private String value;

    public void setValue(String value) {
        try {
            Field field = MyEnum.class.getDeclaredField("value");
            field.setAccessible(true);
            field.set(this, value);
        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }

    public String getValue() {
        return value;
    }
}
