Date format coming from the database: 1629777600000
SimpleDateFormat simpleDateFormatter = new SimpleDateFormat("MM/dd/yyyy");
simpleDateFormat.format(1629777600000);
When using this simple date format I am not able to convert 1629777600000 to a viewable date

SimpleDateFormat simpleDateFormatter = new SimpleDateFormat("MM/dd/yyyy");
System.out.println(simpleDateFormatter.format(1629777600000L));
Print: 08/24/2021
But your code does not compile:
you initialize simpleDateFormatter but use simpleDateFormat (without ter)
1629777600000 is a Long, therefore it needs an L at its end
I think the L problem is just from modifiying the code for the stackoverflow question. But the variable name is maybe a real problem in your code.

I need to use Calendar class. This is my code, but it has an error certainly. How can I fix it?
String stringdate = "20161129";
String pattern = "yyyyMMdd";
Date date = new SimpleDateFormat(pattern).parse(stringdate);
Calendar cal = Calendar.getInstance();
cal.setTime(date);

Your code looks good...
2 things can happen her:
you are not using the correct DAte class (import java.util.Date;)
you are not considering (catching or rethrowing ) the ParseException
in both cases you will get a compilation error...
like type mismatch
or unhandled exception

2013-06-24 15:43:00.0 this is Sting
i want parse that to Date
but in same formate

Use the SimpleDateFormat like this:
String dateString = "2013.06.24 15:43:00";
SimpleDateFormat sdfToDate = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
Date date1 = sdfToDate.parse(dateString);
System.out.println(sdfToDate.format(date1));

I was wondering how I can just set a time such as 10:30am to a Date object from java.util.date? How would I format this? For example Date date1 = 10:30am.

try with the Calendar class then output using SimpleDateFormat
SimpleDateFormat format = new SimpleDateFormat("HH:mma");
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 10);
calendar.set(Calendar.MINUTE, 30);
System.out.println(format.format(calendar.getTime()));

can't do that.Only format to String representations.
SimpleDateFormat simDateFormate = new SimpleDateFormat("hh:mm a");
System.out.println(simDateFormate.format(new Date()));

I have two date objects.
Date d1;
Date d2;
My program stores in d1, the date in the format 'dd/MM/yyyy' and in d2 in the format 'HH:mm'.
I would now like to combine these information and create a new Date object with the format 'dd/MM/yyyy HH:mm'.
Any pointers on how can I achieve so?

If you are indeed using Date objects, just set the time of d1 to match that of d2.
d1.setHours(d2.getHours());
d1.setMinutes(d2.getMinutes());
Or make a new Date object if you don't want to use d1. Just parse it afterwards with SimpleDateFormat.
Note however that this is deprecated and it's better to use Calendar for this.

First, most of functionality of Date is deprecated. Use Calendar instead. Second, to parse and create string representation of date use SimpleDateFormat.
I hope these tips are enough to start. There are a lot of references in net and javadoc to continue. Good luck.

You cannot use Date for this purpose. You should instead use Calendar (from JDK) or joda-time.

try out this..
String dateValue= new java.util.Date().toString();
String concat like this..
String newDateTime = d1+""+d2+":00";

Try this
DateFormat df1=new SimpleDateFormat("dd/MM/yyyy");
DateFormat df2=new SimpleDateFormat("HH:mm");
Date d1=df1.parse("09/07/2013");
Date d2=df2.parse("14:43");
String d=df1.format(d1).toString()+" "+df2.format(d2).toString();
DateFormat newDate=new SimpleDateFormat("dd/MM/yyyy HH:mm");
System.out.println(newDate.format(newDate.parse(d)));
