Another way of doing that is   String date   dateAndTime substring 0  dateAndTime indexOf          I m not exactly certain  but I think this might be faster use less memory than using the  split   method

I have a very dumb but working option   if you have the String fullDate    11 15 2013 08 00 00       String finalDate   fullDate split      0     That should work easy and fast

I think this will work  if you are using JodaTime   String strDateTime    11 15 2013 08 00 00   DateTime dateTime   DateTime parse strDateTime   DateTimeFormatter fmt   DateTimeFormat forPattern  MM dd YYYY    String strDateOnly   fmt print dateTime     I got part of this from here

I am adding this here even though the other answers are completely acceptable  JodaTime has parsers pre built in DateTimeFormat   dateTime toString DateTimeFormat longDate       This is most of the options printed out with their format   shortDate          11 3 16 shortDateTime      11 3 16 4 25 AM mediumDate         Nov 3  2016 mediumDateTime     Nov 3  2016 4 25 35 AM longDate           November 3  2016 longDateTime       November 3  2016 4 25 35 AM MDT fullDate           Thursday  November 3  2016 fullDateTime       Thursday  November 3  2016 4 25 35 AM Mountain Daylight Time

UPDATED    You can  create a constant    private static final DateTimeFormatter DATE FORMATTER YYYY MM DD             DateTimeFormat forPattern  yyyy-MM-dd       or whatever pattern that you need    This DateTimeFormat is importing from   be careful with that      import org joda time format DateTimeFormat     import org joda time format DateTimeFormatter    Parse the Date with   DateTime parse dateTimeScheduled toString    DATE FORMATTER YYYY MM DD     Before   DateTime parse  201711201515  DateTimeFormat forPattern  yyyyMMddHHmm    toString  yyyyMMdd     if want datetime    DateTime parse  201711201515   DateTimeFormat forPattern  yyyyMMddHHmm    withTimeAtStartOfDay
