&quot;equals(in object Other)&quot;<br />
<br />
Without it becomes necessary to create a common base class (comparable) from which all other classes must be derived from, in order to use common data structures and algorithms.<br />
If this function could be added to the object class, an unnecessary layer of abstraction would be elimintaed.<br />
<br />
Also would make it possible (as in C++ and Java) to compare objects based on the internal meaning, rather then their object instances.</td></tr><tr class="print"><td class="print-category">Steps To Reproduce</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Additional Information</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Tags</td><td class="print" colspan="5">No tags attached.</td></tr><tr class="print"><td class="print-category">Relationships</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Attached Files</td><td class="print" colspan="5"><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR_7957.docx (134,667) <span class="italic">12-08-2020 11:50</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3921&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR_7957-2.docx (135,905) <span class="italic">12-08-2020 13:55</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3924&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR_7957-3.docx (152,677) <span class="italic">13-08-2020 09:46</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3931&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR_7957-4.docx (138,091) <span class="italic">13-08-2020 10:06</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3932&amp;type=bug</td></tr><tr><td class="print-spacer" colspan="6"><hr size="1" /></td></tr><tr><td class="form-title">Issue History</td></tr><tr class="print-category"><td class="row-category-history">Date Modified</td><td class="row-category-history">Username</td><td class="row-category-history">Field</td><td class="row-category-history">Change</td></tr><tr class="print"><td class="print">21-05-2020 10:10</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=361">KristÃ³f Szabados</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">10-08-2020 10:31</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=82">Jens Grabowski</a></td><td class="print">Assigned To</td><td class="print"> =&gt;

				I optimized it a little bit further:<br />
1. The comparison to this is the first type of check, because it is the fastest one<br />
2. Rectangle has always 4 sides, so there's no need to check the number of sides nor have a function returning it in this example.<br />
3. I replaced the function for returning a length of a rectangle side with functions returning its width and height which are the properties one would usually expect from a rectangle object.<br />

Please check.<br />
