<a href="https://www.blogger.com/blogger.g?blogID=9141683864977778668" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><br /></a>A big part of developer community has been complaining about Date and
Calender classes. Reasons were many such as hard to understand, hard to use and
not flexible. Date class has even become obsolete and java docs suggest to use
Calender class instead of Date class. And on top of all, Date comparison is
buggy and I have also faced such issue in past.<br />

Moving forward, JAVA 8 (Lambda) is expected to release the new Date and Time
APIs/classes (<a href="https://java.net/projects/jsr-310/" target="_blank" title="jsr-310"><strong><span style="color: windowtext; text-decoration: none; text-underline: none;">JSR-310</span></strong></a>), also called as <strong>ThreeTen</strong>,
which will simply change the way you have been doing till date. This A key part
of this is providing a new API that is dramatically easier to use and less
error prone.<br />

It will provide some highly demanded features such as:<br />

<ul type="disc">
<li class="MsoNormal" style="line-height: normal; mso-list: l2 level1 lfo1; mso-margin-bottom-alt: auto; mso-margin-top-alt: auto; tab-stops: list .5in;">All the
     key public classes are immutable and thread-safe</li>
<li class="MsoNormal" style="line-height: normal; mso-list: l2 level1 lfo1; mso-margin-bottom-alt: auto; mso-margin-top-alt: auto; tab-stops: list .5in;">Defined
     terminology and behavior that other areas in computing can adopt</li>

The current Java SE platform uses int constants for months, day-of-week and
am-pm etc. Now a lot of extra utility classes have been added which work on top
of these enums. I am taking an example such a class <a href="http://download.java.net/jdk8/docs/api/java/time/DayOfWeek.html" target="_blank" title="DayOfWeek"><strong><span style="color: windowtext; text-decoration: none; text-underline: none;">DayOfWeek</span></strong></a>. This
class is a wrapper of day enums and can be used consistently with other classes
also.<br />

Lets see in code.<br />

system/machine clock</span></strong></h3>
A new class <a href="http://download.java.net/jdk8/docs/api/java/time/Clock.html" target="_blank" title="Clock"><strong><span style="color: windowtext; text-decoration: none; text-underline: none;">Clock</span></strong></a> is proposed in new release.
This <strong>simulates the system clock functionality</strong>. I loved this
feature most of all others. The reason is while doing unit testing. you are
often required to test a API in future date. For this we had been forwarding
the system clock for next date, and then again restart the server and test the
application.<br />

Now, no need to do this. Use Clock class to simulate this scenario.<br />
