Convert from Long to date format

Question

I want to convert Long value to String or Date in this format dd/mm/YYYY.

I have this value in Long format: 1343805819061.

It is possible to convert it to Date format?

Answer 1

You can use below line of code to do this. Here timeInMilliSecond is long value.

 String dateString = new SimpleDateFormat("MM/dd/yyyy").format(new Date(TimeinMilliSeccond)); 

Or you can use below code too also.

 String longV = "1343805819061";  long millisecond = Long.parseLong(longV);  // or you already have long value of date, use this instead of milliseconds variable.  String dateString = DateFormat.format("MM/dd/yyyy", new Date(millisecond)).toString(); 

Reference:- DateFormat and SimpleDateFormat

P.S. Change date format according to your need.

Answer 2

You can use method setTime on the Date instance or the contructor Date(long);

setTime(long time)        Sets this Date object to represent a point in time that is time milliseconds after January 1, 1970 00:00:00 GMT.  Date(long date)        Allocates a Date object and initializes it to represent the specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT 

Then use the simple date formater
