Can you override equals method?

Why we override equals() method? It needs to be overridden if we want to check the objects based on the property . For example, we want to check the equality of employee object by the id. Then, we need to override the equals() method.

Only Override HashCode, Use the default Equals: Only the references to the same object will return true . In other words, those objects you expected to be equal will not be equal by calling the equals method. Only Override Equals, Use the default HashCode: There might be duplicates in the HashMap or HashSet.

You can override the equals method on a record, if you want a behavior other than the default . But if you do override equals , be sure to override hashCode for consistent logic, as you would for a conventional Java class.18 Kas 2011
