Convert String to java.sql.Date and java.sql.Time

If I have a method like this:

public static String convertDateTimeToString(DateTime dt) {
    return dt.getDate() + " " + dt.getTime();
}

Which takes a DateTime object of my own which contains a java.sql.Date and a java.sql.Time, what is the best way of reversing the process so that I can substring a java.sql.Date and a java.sql.Time from a String?

Or if DateTime dt is a JodaTime DateT开发者_JS百科ime object?

If this can be done without reference to java.util.Date.

Look at SimpleDateFormat class. Here's a tutorial.

You'll need something like this:

String datetimeString;
Date result;
SimpleDateFormat formatter = new SimpleDateFormat("EEE d MMM yy hh:mm:ss");
result = formatter.parse (datetimeString);

You can use the valueOf method of java.sql.Time to convert a String into a java.sql.Time, and use the valueOf method of java.sql.Date to convert a String into a java.sql.Date
