Two objects are compared by equals() but they have always distinct types.
This checker identifies incorrect or inefficient comparisons through equals() or ==. In some cases, these comparisons are wrong: for instance, strings should be compared for equality through equals() rather than through ==. Classes can be safely compared through == instead. In other cases, these comparisons can be replaced by more efficient code.
