    import java.io.InputStream;
    import java.util.HashMap;

        public static void TimingProperties() throws Exception {
        
            //url 改成你的.properties配置文件的路径，作者这里用的是绝对路径，最好是用相对路径
            String url="C:\\Program Files\\Study\\IntelliJ IDEA 2022.3\\work_space\\测试\\Leetcode\\code.properties";
            File file = new File(url);
            InputStream inputStream = new FileInputStream(file);
            PropertyResourceBundle p = new PropertyResourceBundle(inputStream);
            try {
        
                Set<String> key = p.keySet();
                Map<String, Object> map = new HashMap<>();
                for (String getkey : key) {
        
                    map.put(getkey, p.getString(getkey));
                }
