<p>
Reports code that uses <code>==</code> or <code>!=</code> rather than <code>equals()</code> to test for object equality.
</p>
<p>
Comparing objects using <code>==</code> or <code>!=</code> is often a bug,
because it compares objects by identity instead of equality.
Comparisons to <code>null</code> are not reported.
</p>
<p>
Array, <code>String</code> and <code>Number</code> comparisons are reported by separate inspections.
</p>
<p><b>Example:</b></p>
<pre><code> <b>if</b> (list1 == list2) {
<b>return</b>;
}
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code> <b>if</b> (Objects.equals(list1, list2)) {
<b>return</b>;
}
</code></pre>
<!-- tooltip end -->
<p>Use the inspection settings to configure exceptions for this inspection.</p>
