How to get value from Map key in java
<p>I am trying to receive message attributes from Amazon SQS with the following code :</p>

<pre><code>Map&lt;String, com.amazonaws.services.sqs.model.MessageAttributeValue&gt; attributes = new HashMap&lt;String, com.amazonaws.services.sqs.model.MessageAttributeValue&gt;();
attributes = message.getMessageAttributes();
for(String key: attributes.keySet()){
    System.out.println(key + " - "+ attributes.get(key));
}
</code></pre>

<p>and it returns the output:</p>

<pre><code>project - {StringValue: 25,StringListValues: [],BinaryListValues: [],DataType: String}
</code></pre>

<p>I want to get only the value 25. How do I do that?</p>
