What is the Java equivalent of C++ deque?
<p>in C++ all I had to do was </p>

<pre><code>#include &lt;queue&gt; -&gt; including
queue&lt;int&gt; a; -&gt; defining
a.push(1); -&gt;using
</code></pre>

<p>but in java I found very difficult to use simple deque
what should I do...?
more specifically,
How should I code to simply do the same steps 
as I did in C++; including, defining, using.</p>

<p>even more specifically,
I want to make a deque so that I can
add any integer in the deque at front or back.
and print whole numbers in that deque by the size of the deque </p>
