does currentLine acts as a keyword in java?
<p>I see this line of code which surprised me:</p>

<pre><code>String res = "", currentLine;    
while ((currentLine = rd.readLine()) != null) {
            res+= currentLine;

        }
</code></pre>

<p>the variable currentLine is not defined anywhere before and strangely it does nt throw any error? Does java somehow makes currentLine a keyword here?</p>

<p>Thanks!</p>
