为什么保留34行而不是24行？

package zh.codegym.task.task13.task1316;

/*
错误的行
*/

public class Solution {

    public static void main(String[] args) throws Exception {
        System.out.println(SimpleObject.NAME);
        System.out.println(Button.NAME);
    }

    interface SimpleObject {
        String NAME = "SimpleObject";

        void onPress();
    }

    interface Button extends SimpleObject {

        final String NAME = "提交";

        public void onPress();

        protected void onPress();

        void onPress();

        private void onPress();

        protected String onPress(Object o);

        String onPress(Object o);

        private String onPress(Object o);
    }
}
