i am getting wrong timestamp and my date formatter is right

String RollStart_TIMESTAMP = RollStartDATE_TIME_STAMP+" "+rolStart_TIME_STAMP;
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-mm-yyyy hh:mm");
Date parsedDate = null;
try {
parsedDate = dateFormat.parse(RollStart_TIMESTAMP);
long mili = parsedDate.getTime();
Log.e("VX:","TIMESTAMP"+mili);
} catch (ParseException e) {
e.printStackTrace();
}
Log.e("VX:","TIMESTAMP"+parsedDate);

Try this code, You get a right time stamp.
SimpleDateFormat dateFormat = new SimpleDateFormat("MMMM dd,yyyy HH:mm aaa");
timestamp = dateFormat.format(new Date()); // Find todays date
Log.e("Timestamp", timestamp);

Yes right there is wrong pattern yyyy-MM-hh is helps me out .
try {
String RollStart_TIMESTAMP = RollStartDATE_TIME_STAMP+" "+rolStart_TIME_STAMP;
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");
Date timestamp = null;
timestamp = df.parse(RollStart_TIMESTAMP);
long ROLL_START_DATE_TIME_VALUE = timestamp.getTime()/1000;
Log.e("RX:","VALUE"+ROLL_START_DATE_TIME_VALUE);
} catch (Exception e) {
e.printStackTrace();

How to convert java.util.Date to GMT format

I have a string "2014-07-02T17:12:36.488-01:00" which shows the Mountain time zone. I parsed this into java.util.date format. Now I need to convert this to GMT format. Can anyone help me??
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Object dd = null;
try {
dd=sdf.parseObject("2014-07-02T17:12:36.488-01:00");
System.out.println(dd);
} catch (ParseException e) {
e.printStackTrace();`enter code here`
}
SimpleDateFormat gmtDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
gmtDateFormat.setTimeZone(java.util.TimeZone.getTimeZone("GMT"));
System.out.println("Current Date and Time in GMT time zone:+ gmtDateFormat.format(dd));

There are a few problems in your code. For example, the format string doesn't match the actual format of the string you are parsing.
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX");
Object dd = null;
try {
dd = sdf.parse("2014-07-02T17:12:36.488-01:00");
System.out.println(dd);
} catch (ParseException e) {
e.printStackTrace();
}
SimpleDateFormat gmtDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ssX");
gmtDateFormat.setTimeZone(java.util.TimeZone.getTimeZone("GMT"));
System.out.println("Current Date and Time in GMT time zone:" + gmtDateFormat.format(dd));
To print the current date in whatever timezone you like, set the timezone you want to use on the SimpleDateFormat object. For example:
// Create a Date object set to the current date and time
Date now = new Date();
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX");
df.setTimeZone(TimeZone.getTimeZone("GMT"));
System.out.println("Current date and time in GMT: " + df.format(now));
df.setTimeZone(TimeZone.getTimeZone("IST"));
System.out.println("Current date and time in IST: " + df.format(now));

I want to parse String into java date object [duplicate]

Hello i have date in this format 2013-10-31T19:00:00Z now i want to display this date into yyyy/mm/dd this format.i have used this code but its giving me exception kindly help me
String startDateString = "2013-10-31T19:00:00Z";
DateFormat df = new SimpleDateFormat("yyyy/mm/dd");
Date startDate;
try {
startDate = df.parse(startDateString);
String newDateString = df.format(startDate);
System.out.println("Date is "+newDateString);
} catch (ParseException e) {
e.printStackTrace();
}

Try this
String DateStr="2013-10-31T19:00:00Z";
SimpleDateFormat sim=new SimpleDateFormat("yyyy-MM-dd");
Date d = new SimpleDateFormat("yyyy-MM-dd").parse(DateStr);
System.out.println(sim.format(d));
output 2013-10-31

That's because you're specifically telling Java to look for a 4-digit year followed by a 2-digit month and 2-digit date. Taken straight from the docs, what you want is
"yyyy-MM-dd'T'HH:mm:ssZ"

You can use SimpleDateFormat's parse method to parse your date, and then use the format method to output it in the format that you prefer.
Try this:
String startDateString = "2013-10-31T19:00:00Z";
DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss'Z'");
DateFormat outputFormat = new SimpleDateFormat("yyyy/MM/dd");
Date date = inputFormat.parse(startDateString);
System.out.println("Date is " + outputFormat.format(date));
Output:
Date is 2013/10/31

You need a separate SimpleDateFormat to parse the Datestring. Try this:
String startDateString = "2013-10-31T19:00:00Z";
DateFormat originalFormat = new SimpleDateFormat("yyyy-mm-dd'T'HH:MM:SS'Z'");
DateFormat df = new SimpleDateFormat("yyyy/mm/dd");
Date startDate;
try {
startDate = originalFormat.parse(startDateString);
String newDateString = df.format(startDate);
System.out.println("Date is " + newDateString);
} catch (ParseException e) {
e.printStackTrace();
}

You need two different DateFormat. one for parse date and one for formatting date.
String startDateString = "2013-10-31T19:00:00Z";
DateFormat df = new SimpleDateFormat("yyyy/mm/dd");
DateFormat df1 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:SS'Z'");
Date startDate;
try {
startDate =df1.parse(startDateString);
String newDateString = df.format(startDate);
System.out.println("Date is "+newDateString);
} catch (ParseException e) {
e.printStackTrace();
}

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String dateInString = "07/06/2013";
try {
Date date = formatter.parse(dateInString);
System.out.println(date);
System.out.println(formatter.format(date));
} catch (ParseException e) {
e.printStackTrace();
}
Here is simple example

Try this:
try {
String startDateString = "2013-10-31T19:00:00Z";
DateFormat input = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss'Z'");
DateFormat output = new SimpleDateFormat("yyyy/MM/dd");
Date date = input.parse(startDateString);
System.out.println("Date is " + output.format(date));
} catch (ParseException e) {
e.printStackTrace();
}
Pointing an another simple mistake in your code
You coded as DateFormat df = new SimpleDateFormat("yyyy/mm/dd");
here mm is for minutes , for month use MM

convert string to date and format the date

I have String variable which contains date. Now how to display July 15 from that string variable? (for example 2012-07-15)
String strdate = "2012-07-15";
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MMM-dd");
try {
d1 = formatter.parse(strdate);
System.out.println(d1 + "---date first---");
} catch (ParseException e) {
e.printStackTrace();
}

Your parsing template does not match your example:
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
(with MM instead of MMM).
To output July 15, you can use a second formatter:
SimpleDateFormat output = new SimpleDateFormat("MMMM dd");
System.out.println(output.format(d1)); //July 15

Something like,
try {
String strdate = "2012-07-15";
DateFormat df1 = new SimpleDateFormat("yyyy-MM-dd"");
DateFormat df2 = new SimpleDateFormat("MMMM dd");
System.out.println(df2.format(df1.parse(strdate)+ "---date first---");
}
catch (ParseException e) {
// Exception handling
}

How to Convert the Following string into Date Object?

I am New to Android Development.How to convert the Following string(5/31/2011) in to the Date Object I tried different ways But Couldn't get any Luck??

String dateStr = "5/31/2011";
DateFormat df = new SimpleDateFormat("M/dd/yyyy");
Date date = df.parse(dateStr);

DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
try {
Date today = df.parse("5/31/2011");
System.out.println("Today = " + df.format(today));
} catch (ParseException e) {
e.printStackTrace();
}

You can use the following
String time1 = "5/31/2011";
SimpleDateFormat formatter1 = new SimpleDateFormat("MM/dd/yyyy");
Date indate1 = formatter1.parse(time1);
