HashMap Java get value if it exists
<p>I wish to get a value from a HasMap but some time the value doesn't exist so I have done this:</p>

<pre><code>int var = 0;
if (hashMapHouse.containsKey("home1") {
    var = hashMapHouse.get("houme1");
}
if(var==0) //do something
else //do something else
</code></pre>

<p>My question is: is it possible to have one call of hashMap in order to get the value and to test if the value exist or no?</p>
