如何从日期时间字符串中分割日期和时间？

一种方法是将其解析为日期对象，然后重新格式化：

    try {        DateFormat f = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss a");        Date d = f.parse("8/29/2011 11:16:12 AM");        DateFormat date = new SimpleDateFormat("MM/dd/yyyy");        DateFormat time = new SimpleDateFormat("hh:mm:ss a");        System.out.println("Date: " + date.format(d));        System.out.println("Time: " + time.format(d));    } catch (ParseException e) {        e.printStackTrace();    }

如果您只想将其切成日期时间片段，只需使用split来获取片段

    String date = "8/29/2011 11:16:12 AM";    String[] parts = date.split(" ");    System.out.println("Date: " + parts[0]);    System.out.println("Time: " + parts[1] + " " + parts[2]);

要么

    String date = "8/29/2011 11:16:12 AM";    System.out.println("Date: " + date.substring(0, date.indexOf(' ')));    System.out.println("Time: " + date.substring(date.indexOf(' ') + 1));
