    How do I convert 'timeStamp' to date after I get the count in java?

    My current code is as follows:

    public class GetCurrentDateTime {

    public int data() {

    int count = 0;

    java.sql.Timestamp timeStamp = new Timestamp(System.currentTimeMillis());

    java.sql.Date date = new java.sql.Date(timeStamp.getTime());

    System.out.println(date);

    //count++;

    try {

    Class.forName("com.mysql.jdbc.Driver");

    Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/pro", "root", "");

    PreparedStatement statement = con.prepareStatement("select * from orders where status='Q' AND date=CURDATE()");

    ResultSet result = statement.executeQuery();

    while (result.next()) {

    // Do something with the row returned.

    count++; //if the first col is a count.

    }

    } catch (Exception exc) {

    System.out.println(exc.getMessage());

    }

    return count;

    }

    }

    This is my database:

    4wXsC.png

    Here the output I got was 2012-08-07 0, but the equivalent query returns 3. Why do I get 0?

    解决方案

    Just make a new Date object with the stamp's getTime value as a paramater

    Here's an example (I use an example timestamp of the current time):

    Timestamp stamp = new Timestamp(System.currentTimeMillis());

    Date date = new Date(stamp.getTime());

    System.out.println(date);

    来自:http://outofmemory.cn/code-snippet/1730/C-jiang-unix-Timestamp-switch-Date-type-time

    在unix/linux或者mysql中都有类似时间戳,这个时间是从1970-1-1零点零分零秒的时间后经过的秒数。

    public static DateTime UnixTimeStampToDateTime( double unixTimeStamp )
    {
        // 定义其实时间
        System.DateTime dtDateTime = new DateTime(1970,1,1,0,0,0,0);
        dtDateTime = dtDateTime.AddSeconds( unixTimeStamp ).ToLocalTime();
        return dtDateTime;
    }
    知道了原理我们也可以很方便的将时间转换为unix timestamp

    public static double DateTimeToUnixTimestamp(DateTime dateTime)
    {
        return (dateTime - new DateTime(1970, 1, 1).ToLocalTime()).TotalSeconds;
    }
