java - java.util.Date 语言环境中的 toString() 方法是否独立？

Question

    try {
         SimpleDateFormat strTemp = new SimpleDateFormat("ddMMMyy", Locale.US);
          Date reasult = strTemp.parse(input);
         String   checkDate = reasult.toString().substring(8, 10) + reasult.toString().substring(4, 7) + reasult.toString().substring(26);
         if (!checkDate.toUpperCase().equals(input))
             return false;

         else
          return true;
       } catch (Exception ex) {
            return false;
     }

API 告诉我 java.util.Date.toString() 就像格式“dow mon dd hh:mm:ss zzz yyyy”，我只想知道 toString() 的内容格式是否会改变Windows 语言环境改变了吗？比如“俄语”，“英语”，提示输入相同，checkDate值相同？感谢您的帮助。

Answer 1

Date.toString() 与语言环境无关。您可以观察到的最显着的变化是时区，这取决于您计算机的时区设置。这是 by design .

Converts this Date object to a String of the form:

   dow mon dd hh:mm:ss zzz yyyy

where:

• dow is the day of the week (Sun, Mon, Tue, Wed, Thu, Fri, Sat).
• mon is the month (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec).
• dd is the day of the month (01 through 31), as two decimal digits.
• hh is the hour of the day (00 through 23), as two decimal digits.
• mm is the minute within the hour (00 through 59), as two decimal digits.
• ss is the second within the minute (00 through 61, as two decimal digits.
• zzz is the time zone (and may reflect daylight saving time). Standard time zone abbreviations include those recognized by the method parse. If time zone information is not available, then zzz is empty - that is, it consists of no characters at all.
• yyyy is the year, as four decimal digits.
