If you are using Java 8, you should not use <code>java.util.Date</code> in the first place (unless you receive the <code>Date</code> object from a library that you have no control over).

In any case, you can convert a <code>Date</code> to a <code>java.time.Instant</code> using:

<pre><code>Date date = ...;
Instant instant = date.toInstant();
</code></pre>

Since you are only interested in the date and time, without timezone information (I assume everything is UTC), you can convert that instant to a <code>LocalDateTime</code> object:

<pre><code>LocalDateTime ldt = instant.atOffset(ZoneOffset.UTC).toLocalDateTime();
</code></pre>

Finally you can print it with:

<pre><code>DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss");
System.out.println(ldt.format(fmt));
</code></pre>

Or use the predefined formatter, <a href="https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html#ISO_LOCAL_DATE_TIME" rel="noreferrer"><code>DateTimeFormatter.ISO_LOCAL_DATE_TIME</code></a>.

<pre><code>System.out.println(ldt.format(DateTimeFormatter.ISO_LOCAL_DATE_TIME));
</code></pre>

Note that if you don't provide a formatter, calling <a href="https://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html#toString--" rel="noreferrer"><code>ldt.toString</code></a> gives output in standard <a href="https://en.wikipedia.org/wiki/ISO_8601" rel="noreferrer">ISO 8601</a> format (including milliseconds) - that may be acceptable for you.

System.out.println(ldt.format(fmt));

How can I convert a <code>java.util.Date</code> to <code>String</code> using 

<pre><code> DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss")

The Date object which I get is passed
