Format time from miliseconds to show only the date [duplicate] - java

This question already has answers here:
Java Date Format for Locale
(2 answers)
Closed 9 years ago.
Sorry if my question has already been answered, but I can't really find what I am looking for.
So I have this time "1228061700000" and I want to convert it to show only the date, like this 17/6/08.
It would also be good to check for the locale, so for US locale the format to be like this 6/17/08 and for european locale to be 17/6/08... How can I do it?

Use a DateFormat:
DateFormat f = DateFormat.getDateInstance(DateFormat.SHORT, Locale.ENGLISH);
String result = f.format(new Date(millis));

long milliSeconds=1228061700000l;
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); //change your date time formate as required
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(milliSeconds);
System.out.println(formatter.format(calendar.getTime()));

DateFormat.getDateInstance(int style, Locale aLocale)This displays the current date in a locale-specific way.
So, you can try:
DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, yourLocale);
String formattedDate = df.format(yourDate);
In this case you can choose what type of yourDate is.
Your locate can be changed to Locale.UK Locale.US and etc.

The following code gave me Datetimestamp as [ 2020-07-183 17:07:55.551 ]. The issue is with "Day" in Datetimestamp, which has three digits. How to format currentTimeMillis into the right format for day of month?
public String Datetimesetter(long currentTimeMillis, SimpleDateFormat dateFormat) {
dateFormat = new SimpleDateFormat("YYYY-MM-DD HH:MM:SS.SSS");
// Create a calendar object that will convert the date and time value in milliseconds to date.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(currentTimeMillis);
return dateFormat.format(calendar.getTime());
}
SOLUTION WHICH WORKED FOR ME:
Please visit this link.
This is for the case you are supporting Apps from API level 26 (native support of java.time) or you are willing / allowed to use a backport library of the same functionality.
Then you can use a correct / matching pattern (one that considers three-digit days) like this:
public static void main(String[] args) {
// mock / receive the datetime string
String timestamp = "2020-07-183 17:07:55.551";
// create a formatter using a suitable pattern (NOTE the 3 Ds)
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("uuuu-MM-DDD HH:mm:ss.SSS");
// parse the String to a LocalDateTime using the formatter defined before
LocalDateTime ldt = LocalDateTime.parse(timestamp, dtf);
// and print its default String representation
System.out.println(ldt);
}
which outputs
2020-07-01T17:07:55.551
So I guess the day of year no. 183 was actually July 1st.
your date format is incorrect
dateFormat = new SimpleDateFormat("YYYY-MM-DD HH:MM:SS.SSS");
change to this
dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:MM:SS.SSS");

How to show date without year based on locale in Java? [duplicate]

This question already has an answer here:
Localize string from `MonthDay` or `YearMonth` classes in java.time? [duplicate]
(1 answer)
Closed 3 years ago.
I use DateFormat and locale to show Day and Month. DateFormat supports MEDIUM, LONG, FULL all have a year.I only want to show month and day.
I tried to use SimpleDateFormat, but SimpleDateFormat defined the order of month and day. In different countries, date format is different. I don't want to define the order of month and day. I hope the date format is decided by locale.
Here is my code and how can I remove year from the date?
Locale myLocale =Locale.FRANCE;
DateFormat localFormatter = DateFormat.getDateInstance(DateFormat.MEDIUM, myLocale);
String localDate = localFormatter.format(date);
I tried the following locale and print the date on the right:
Locale myLocale =Locale.FRANCE; localDate=1 avr. 2018
Locale myLocale =Locale.CHINA; localDate=2018-4-1
Locale myLocale =Locale.JAPAN; localDate=2018/04/01
A localized DateFormat may or may not be a SimpleDateFormat, so you can’t be certain it will have a pattern. However, you can obtain a localized DateTimeFormatter pattern, and strip the year from that:
public static Format createMonthDayFormat(FormatStyle style,
Locale locale) {
String pattern = DateTimeFormatterBuilder.getLocalizedDateTimePattern(
style, null, Chronology.ofLocale(locale), locale);
pattern = pattern.replaceFirst("\\P{IsLetter}+[Yy]+", "");
pattern = pattern.replaceFirst("^[Yy]+\\P{IsLetter}+", "");
DateTimeFormatter formatter =
DateTimeFormatter.ofPattern(pattern, locale);
return formatter.toFormat();
}
There is a catch, however. The returned Format cannot format Date or Calendar objects. It expects Temporal objects like LocalDate or ZonedDateTime. You will need to convert a java.util.Date to such an object:
Format format = createMonthDayFormat(FormatStyle.SHORT, Locale.getDefault());
Date date = new Date();
String text = format.format(
date.toInstant().atZone(ZoneId.systemDefault()));

JSON date to formatted JAVA date [duplicate]

Java: Date from unix timestamp
(11 answers)
Closed 6 years ago.
I am trying to get dd.MM.yyyy and hh:mm from 1436536800 but only the time is correct, the date is completely wrong. I don't really understand how this is supposed to work
int dt = time.getInt("start")*1000;
Date date = new Date(dt);
startDate = dateFormat.format(date);
If time.getInt("start") is a valid unix timestamp, you must add "000" to the number. Example: 1436536800 * 1000 = 1436536800000. Then you can use the timestamp to get a Date:
final Date date = new Date(Long.parseLong("1436536800000"));
SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy hh:mm");
System.out.println(sdf.format(date));
Console exit: 10.07.2015 09:00
Assuming the time is correct, it's likely the fact that you're multiplying by 1,000. When creating the date the way you are, it takes in milliseconds. Is it possible that your input is already in milliseconds? (Your current method will be ~2 minutes off if so)
Date date=new Date(1436536800);
SimpleDateFormat df2 = new SimpleDateFormat("dd.MM.yyyy");
String dateText = df2.format(date);
Date you are getting is a JSON string value. follow steps below to format it correctly.
First download Moment.js file and add it in your project.
var date1 = "1436536800"; // your long value contain in this variable.
var date2 = moment(date1).format(MMMM Do YYYY);//It will give you formatted date value.

I really need your help. I have searched and tried every example I could use, but none have worked.
I need to store current date in YYYY-MM-DD format in a text file..the String date has to be a string..
String dateF = "YYYY-MM-DD";
Date dateOnly = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat(dateF);
String date = dateFormat.format(dateOnly);
when I tried that code above.. this the output I got
please|work|2016-04-110|11
please help me...this is my assignment due this Friday ): I just need this date and 2 other things to be done..
thanks :)
your issue comes from the case you used for Y and D. according to the API SimpleDateFormat documentation, you should use d (day in month) instead of D (day in year), in your format definition.
String dateF = "yyyy-MM-dd";
Format being used is incorrect.
YYYY-MM-DD : Capital DD will return Day in the year. So, 11 April corresponds to 110th day in the year.
yyyy-MM-dd : Small dd will return the Day in the month.
Refer: https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
Use this code :
Calendar c = Calendar.getInstance();
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
String formattedDate = formatter.format(c.getTime());
The formattedDate contain 2016-04-19
Edit :
In your code change the YYYY to yyyy and DD to dd.

I need to get date format like:
"yyyy-mm-dd am"
or
"yyyy-mm-dd pm"
In Java for Android
I do not need current time, only yyyy-mm-dd plus am/pm
how to make it directly ?
i use the method below to get current date:
private static String getDate(){
Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-mm-dd");
return sdf.format(c.getTime());
}
You can simply use
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-mm-dd a");
Output will be
2015-34-20 AM
EDIT
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd a");
this will produce an output of
2015-05-20 AM
You should use these below lines of code...There is only one problem with the SimpleDateFormat is that when ever you change the device language to another language than SimpleDateFormat's string also changes with the language which can create problem in yours application..Therefore i suggest you if you do not want to change the date string according the application language changes than Use below concept which become helpful for you Or Just simply use SimpleDateFormat for not changing the application language to another langauge.
Calendar ci = Calendar.getInstance();
String AM_PM;
if(ci.get(Calendar.AM_PM)==0)
{
AM_PM ="AM";
}
else
{
AM_PM ="PM";
}
String CiDateTime = "" + ci.get(Calendar.YEAR) + "-" +
(ci.get(Calendar.MONTH) + 1) + "-" +
ci.get(Calendar.DAY_OF_MONTH)+" "+AM_PM;
System.out.println("time=========================================="+CiDateTime);
Output:-
time==========================================2015-5-20 PM
