If that is your exact code, do you mean it doesn't compile? What isn't working exactly? I ran the code and it runs fine and shows the correct date.

No need for strings, no need for java. The ThreeTen-Extra project extends java. time with additional classes. This project is a proving ground for possible future additions to java. You may find some useful classes here such as Interval , YearWeek , YearQuarter , and more. Your Problem is because of getTime. it always return following.

It is impossible to display the current date in milliseconds as an integer 10 digit number , because the latest possible date is Sun Apr 26 MSK :.

Simple really create a long variable that represents a default start date for your program Get the date to another long variable. Then deduct the long start date and convert to a integer voila To read and convert back just add rather than subtract.

But my requirement is to maintain only integer not long.. Is there any other way to achieve my requirement. If you're willing to live with a resolution of one second you would lose the milliseconds component of the date then you could divide by prior to storing the integer. And multiply to convert back. However it would have a limited life a sort of Y2K issue - up to I have added code to my answer to demonstrate the suggestion above — shonky linux user.

FYI, counting whole seconds since beginning of UTC while ignoring leap seconds is known as Unix Time. Note that YearMonth. If you are not using Java 8, consider using Joda Time which has a similar class in fact, Java 8's new date and time API is based on Joda Time.

I want to convert the current date to integer value. By default, it returns long. When I try to convert long to integer, and afterwards I convert the integer value to date, means it shows 's date,.

The issue is that an Integer is not large enough to store a current date, you need to use a Long. The maximum Integer value is , whereas the number of milliseconds since is currently in the order of In order to get current date as integer 10 digit number , you need to divide the long returned from new Date.

getTime by As others stated, a bit integer cannot hold a number big enough for the number of seconds from the epoch beginning of in UTC and now. You need bit integer a long primitive or Long object. The other answers are using old legacy date-time classes. They have been supplanted by the java. time classes. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds. You can interrogate for the number of milliseconds since the epoch.

Beware this means a loss of data, truncating nanoseconds to milliseconds. If you want a count of nanoseconds since epoch, you will need to do a bit of math as the class oddly lacks a toEpochNano method. Note the L appended to the billion to provoke the calculation as bit long integers. But the end of the Question asks for a digit number. I suspect that means a count of whole seconds since the epoch of T This is commonly referred to as Unix Time or Posix Time.

We can interrogate the Instant for this number. Again, this means a loss of data with the truncation of any fraction-of-second this object may hold. The java. time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.
