Why am I getting a java.lang.Charsequence cannot be applied to a char error?
<pre><code> }else if(readUserEmail.contains('a')){
        System.out.print("true");
</code></pre>

<p>Why am I getting a <code>java.lang.Charsequence</code> cannot be applied to a char error? In this case <code>readUserEmail</code> is a string of an email.</p>
