I’ve created a complex object in Java and I’m comparing it using the equals method.
Is this okay or is it preferred to give the object a name or an id and compare the objects names/ids?

You should use the
equals()method. If you want to make equality a name and/or id comparison, do it inside theequals()method.It is the default way that Java determines equality.

There’s a relationship between
equals()andhashcode(). Both of these are used by Collections.
