Answer
Use immutable objects or synchronize access.
To ensure thread safety, make objects immutable or synchronize access to mutable fields used in equals and hashCode. In a multithreaded environment, this prevents race conditions where methods return inconsistent results. For example, using an immutable Product object ensures consistent behavior when used in collections.
