Answer 1

Try this,

SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy-MM-dd");
    Date dateD=new Date();
    dateD.setTime(LongTime);
    date=dateFormat.format(dateD);

Answer 2

Try this

Date date1 = new SimpleDateFormat("MMddyyyySSS").parse(strDate1);

Hope it will works for 12302012235 , but i assume 235 is millisec.

Answer 3

Java 8, Convert milliseconds long to Date as String by given date format pattern. If you have a long milliseconds and want to convert them into date string at specifies time zone and pattern, then you can use it:-

dateInMs is a long value of DateTime.

DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
                    .format(Instant.ofEpochMilli(dateInMs).atZone(ZoneId.of("Europe/London")))

Answer 4

You can try following code:

private Date getGMTDate(long date) {
    SimpleDateFormat dateFormatGmt = new SimpleDateFormat(
            "yyyy-MMM-dd HH:mm:ss");
    dateFormatGmt.setTimeZone(TimeZone.getTimeZone("GMT"));
    SimpleDateFormat dateFormatLocal = new SimpleDateFormat(
            "yyyy-MMM-dd HH:mm:ss");

    Date temp = new Date(date);

    try {
        return dateFormatLocal.parse(dateFormatGmt.format(temp));
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return temp;
}  

I hope this will help you.

Answer 5

Try the following code segment:

        Calendar c = Calendar.getInstance();
        c.setTimeInMillis(Long.parseLong(val));         
        Date d = (Date) c.getTime();        
        SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy");       
        String time = format.format(d);//this variable time contains the time in the format of "day/month/year".    

Answer 6

i got the answer.actually i wanted to convert the string to date only for comparing the values.since i am getting the value as long i directly used the compareTo function to do this.avoided the conversion of long to string and string to date conversion.thank you all for support.
