如何从日期时间戳获取时间和日期

Question

我有1个字符串像8/29/2011 11:16:12 AM我想保存在变量中,如date = 8/29/2011和time = 11:16:12 AM

怎么可能？你能举个例子吗？

Answer 1

一种方法是将其解析为日期对象并重新格式化:

    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();
    }

如果你只想将它切成日期时间片段,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));
