|| operator cannot be used in equalsIgnoreCase() method argument?
<pre><code>boolean hasTaxes(){
        return !state.equalsIgnoreCase("TX" || "NM" ||"VA" || "AZ" || "AK");
    }
</code></pre>

<p>In the above code, I got <code>The operator || is undefined for the argument type(s) java.lang.String, java.lang.String</code> error... so does that mean <code>||</code> operator cannot be used in <code>equalsIgnoreCase()</code> argument?</p>
