There are two sheets:<br>

I want to compare two sheets by their content in an object. <br>

Question: What is wrong here and how to implement it correctly? <br>
the code:<br>
<pre><code class="java hljs"><span class="hljs-keyword">private</span> List<PaymentRBS> rbsList;
<span class="hljs-keyword">private</span> List<PaymentPartner> partnerList;

<span class="hljs-keyword">for</span> (PaymentRBS rbs : rbsList) {
found = partnerList.stream()
.filter(paymentPartner ->
paymentPartner.getAccount().equals(rbs.getAccount()) && paymentPartner.getSum() == rbs.getSum())
.collect(Collectors.toList());
}
found.forEach(System.out::println);

<p class="answer__detail">I would do this: <br>
1. Make a map from both sheets, where the key is the number, accounts, and the value is the object itself. <br>
2. By this key, I would combine both maps into one, but the value would be <code class="hljs">Tupple2<PaymentRBS, PaymentPartner></code>. That. in one tapple there would be both objects with the same account number. <br>
3. According to the values in the final collection, it will be possible to perform all the operations of interest.</p>
