如何在Java中获取时间分隔符符号？

Question

有没有办法在Java中获得时间分隔符符号'：'？它在某个地方还是一个吸气者？也许有相当于File.separator的东西？

我的时间字符串由DateFormat.getTimeInstance(DateFormat.SHORT, locale).format(date);

返回它是安全的，只要用“：”在这种情况下，当后来有人想解析这个字符串？

Answer 1

我认为使用':'是安全的。它在SimpleDateFormat中被硬编码。例如：

if (text.charAt(++pos.index) != ':') 

Answer 2

请尝试以下

public static String getTimeSeparator(Locale locale) { 
    String sepValue = ":"; 

    DateFormat dateFormatter = DateFormat.getTimeInstance(DateFormat.SHORT, 
       locale); 
    DateFormatSymbols dfs = new DateFormatSymbols(locale); 
    Date now = new Date(); 

    String[] amPmStrings = dfs.getAmPmStrings(); 
    String localeTime = dateFormatter.format(now); 
    //remove the am pm string if they exist 
    for (int i = 0; i < amPmStrings.length; i++) { 
     localeTime = localeTime.replace(dfs.getAmPmStrings()[i], ""); 
    } 

    // search for the character that isn't a digit. 
    for (int currentIndex = 0; currentIndex < localeTime.length(); currentIndex++) { 
     if (!(Character.isDigit(localeTime.charAt(currentIndex)))) 
     { 
     sepValue = localeTime.substring(currentIndex, currentIndex + 1); 
     break; 
     } 
    } 

    return sepValue; 
}
