"Mar 10, 2016 6:30:00 PM" This is my date and I want to convert this into "10 Mar 2016". Can I use SimpleDateFormat in android. I am not getting the exact pattern to convert it. Please help and thanks in advance
String date="Mar 10, 2016 6:30:00 PM";
SimpleDateFormat spf=new SimpleDateFormat("Some Pattern for above date");
Date newDate=spf.format(date);
spf= new SimpleDateFormat("dd MMM yyyy");
String date = spf.format(newDate);
Will this steps work? If yes, can someone please give me a pattern of that format? Thanks in advance.
This is modified code that you should use:
String date="Mar 10, 2016 6:30:00 PM";
SimpleDateFormat spf=new SimpleDateFormat("MMM dd, yyyy hh:mm:ss aaa");
Date newDate=spf.parse(date);
spf= new SimpleDateFormat("dd MMM yyyy");
date = spf.format(newDate);
System.out.println(date);
Use hh for hours in order to get correct time.
Java 8 and later
Java 8 introduced new classes for time manipulation, so use following code in such cases:
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMM dd, yyyy h:mm:ss a");
LocalDateTime dateTime = LocalDateTime.parse(date, formatter);
DateTimeFormatter formatter2 = DateTimeFormatter.ofPattern("dd MMM yyyy");
System.out.println(dateTime.format(formatter2));
Use h for hour format, since in this case hour has only one digit.
conversion from string to date and date to string
String deliveryDate="2018-09-04";
SimpleDateFormat dateFormatprev = new SimpleDateFormat("yyyy-MM-dd");
Date d = dateFormatprev.parse(deliveryDate);
SimpleDateFormat dateFormat = new SimpleDateFormat("EEE dd MMM yyyy");
String changedDate = dateFormat.format(d);
You can use following method for this problem. We simply need to pass Current date format, required date format and Date String.
private String changeDateFormat(String currentFormat,String requiredFormat,String dateString){
String result="";
if (Strings.isNullOrEmpty(dateString)){
return result;
}
SimpleDateFormat formatterOld = new SimpleDateFormat(currentFormat, Locale.getDefault());
SimpleDateFormat formatterNew = new SimpleDateFormat(requiredFormat, Locale.getDefault());
Date date=null;
try {
date = formatterOld.parse(dateString);
} catch (ParseException e) {
e.printStackTrace();
}
if (date != null) {
result = formatterNew.format(date);
}
return result;
}
This method will return Date String in format you require.
In your case method call will be:
String date = changeDateFormat("MMM dd, yyyy hh:mm:ss a","dd MMM yyyy","Mar 10, 2016 6:30:00 PM");
You should parse() the String into Date and then format it into the desired format. You can use MMM dd, yyyy HH:mm:ss a format to parse the given String.
Here is the code snippet:
public static void main (String[] args) throws Exception
{
String date = "Mar 10, 2016 6:30:00 PM";
SimpleDateFormat spf = new SimpleDateFormat("MMM dd, yyyy hh:mm:ss a");
Date newDate = spf.parse(date);
spf = new SimpleDateFormat("dd MMM yyyy");
String newDateString = spf.format(newDate);
System.out.println(newDateString);
}
Output:
10 Mar 2016
For the sake of completeness, here is the modern version. This is for anyone reading this who either uses Java 8 or later or is happy with a (good and futureproof) external library.
String date = "Mar 10, 2016 6:30:00 PM";
DateTimeFormatter parseFormatter
= DateTimeFormatter.ofPattern("MMM d, uuuu h:mm:ss a", Locale.ENGLISH);
DateTimeFormatter newFormatter
= DateTimeFormatter.ofPattern("d MMM uuuu", Locale.ENGLISH);
date = LocalDateTime.parse(date, parseFormatter).format(newFormatter);
System.out.println(date);
This prints the desired
10 Mar 2016
Please note the use of explicit locale for both DateTimeFormatter objects. “Mar” and “PM” both are in English, so neither the parsing nor the formatting will work unless some English-speaking locale is used. By giving it explicitly we are making the code robust enough to behave as expected also on computers and JVMs with other default locales.
To use the above on Android, use ThreeTenABP, please see How to use ThreeTenABP in Android Project. On other Java 6 and 7 use ThreeTen Backport.
You need to use SimpleDateFormat class to do the needful for you
String date = "Your input date"
DateFormat originalFormat = new SimpleDateFormat("<Your Input format here>", Locale.US)
DateFormat targetFormat = new SimpleDateFormat("<Your desired format here>", Locale.US)
Date Fdate = originalFormat.parse(date)
formattedDate = targetFormat.format(Fdate)
public static String formatDate(String fromFormat, String toFormat, String dateToFormat) {
SimpleDateFormat inFormat = new SimpleDateFormat(fromFormat);
Date date = null;
try {
date = inFormat.parse(dateToFormat);
} catch (ParseException e) {
e.printStackTrace();
}
SimpleDateFormat outFormat = new SimpleDateFormat(toFormat);
return outFormat.format(date);
}
Use:
formatDate("dd-MM-yyyy", "EEEE, dd MMMM yyyy","26-07-2019");
Result:
Friday, 26 July 2019
How to convert date fromat from "dd MMM yyyy" to "yyyy-MM-dd"?
I know I have to use SimpleDatFormat but it doesn't work, neither does any solution from similar questions.
I have a date "18 Dec 2015" that I am trying to format but I get this
java.text.ParseException: Unparseable date: "18 Dec 2015"
Here's my code:
public String parseDate(String d) {
String result = null;
Date dateObject = null;
SimpleDateFormat dateFormatter = new SimpleDateFormat("dd MMM yyyy");
try {
dateObject = dateFormatter.parse(d);
dateFormatter.applyPattern("yyyy-MM-dd");
result = dateFormatter.format(dateObject);
} catch (ParseException e) {
System.out.println(e);
}
return result;
}
Did you try
SimpleDateFormat dateFormatter = new SimpleDateFormat("dd-MMM-yyyy");
instead of
SimpleDateFormat dateFormatter = new SimpleDateFormat("dd MMM yyyy");
(note the hyphens, since your pattern doesn't match your input)
Also helpful: using Locale.US as recommended by #ZouZou
You are passing input as "18-Dec-2015" instead of the form "dd MMM yyyy". Try and pass input like 18 Dec 2015 and it should work.
I'm parsing a UTC Date string with SimpleDateFormat and it is parsed as the previous date.
DateFormat df = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z");
This string "Fri, 06 Apr 2012 04:00:00 GMT" is being parsed as 4/5/2012. Why? Thanks.
Below is example of date conversion...
For your program, do changes accordingly and let me know what output you are getting.
String dateStr = "Thu Jan 19 2012 01:00 PM";
DateFormat readFormat = new SimpleDateFormat( "EEE MMM dd yyyy hh:mm aaa");
DateFormat writeFormat = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss");
Date date = null;
try {
date = readFormat.parse( dateStr );
} catch ( ParseException e ) {
e.printStackTrace();
}
String formattedDate = "";
if( date != null ) {
formattedDate = writeFormat.format( date );
}
System.out.println(formattedDate);
Output is 2012-01-19 13:00:00
Do the changes as per output you are expecting.
Beware of JDK 1.5.0_22 (linux). Produces incorrect date. Switched to JDK 1.6 problem gone.
I have string in 'MM/dd/yyyy' format and want to convert it into 'dd-MM-yy'.
e.g. '04/01/2012' should be converted into '01-Apr-12'
Can anyone please suggest how to get this?
SimpleDateFormat currentFormat = new SimpleDateFormat("mm/dd/yyyy");
SimpleDateFormat newFormat = new SimpleDateFormat("dd-mm-yy");
String dateInOldFormat="04/01/2012";
Date temp = currentFormat.parse(dateInOldFormat);
String dateInNewFormat= newFormat.format(temp);
i think things are pretty simple from here on...
You can use the Date class in Java. Parse a string with your format, and then output using a different format.
Below is example of date conversion... For your program, do changes accordingly...
String dateStr = "Thu Jan 19 2012 01:00 PM";
DateFormat readFormat = new SimpleDateFormat( "EEE MMM dd yyyy hh:mm aaa");
DateFormat writeFormat = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss");
Date date = null;
try {
date = readFormat.parse( dateStr );
} catch ( ParseException e ) {
e.printStackTrace();
}
String formattedDate = "";
if( date != null ) {
formattedDate = writeFormat.format( date );
}
System.out.println(formattedDate);
Output is 2012-01-19 13:00:00
Good Luck
Can any one help in conversion of date format?
My returned date object is contains "Mon Jul 12 00:00:00 IST 2010"
I'm trying to convert this date format to "MM/dd/yyyy" but I'm getting parse exception. Please help me how to convert it
Code from the OP's comment:
String mydatObj = myDate.toString();
Date formatedDate = getDateFormat(mydatObj);
public static Date getDateFormat(String dateString) {
Date date = null;
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy");
try {
// set isLenient to false to adhere to the date format.
format.setLenient(false);
date = format.parse(dateString);
} catch (ParseException parseException) {
// ignore
LOG.error(parseException.getMessage(), parseException);
}
return date;
}
Well, you are getting a ParseException since you are trying to parse a date with the wrong format.
Here is a small code snippet which will work with the format you have:
// parse the date
DateFormat f = new SimpleDateFormat("E MMM dd HH:mm:ss zzz yyyy");
Date d = f.parse("Mon Jul 12 00:00:00 IST 2010"); // works
// now print the date
DateFormat out = new SimpleDateFormat("MM/dd/yyyy");
System.out.println(out.format(d));
