java : Unknown return ('L') type for boolean value
<p>In this method the symbol value can be anything Stock Symbol like (For example GOOG , C , DAC-----etc)</p>

<pre><code>private boolean isC(String symbol) {
    char code = symbol.charAt(symbol.length() - 2);
    return code &lt;= 'L';
}
</code></pre>

<p>Could anybody please let me know what does this return type mean exactly ??</p>

<p>I am confused because i was thinking of a return type to be either <code>true</code> or <code>false</code>, but could anybody please let me know what does this  <code>'L'</code> mean exactly ??</p>

<p>Thanks in advance .</p>
