2) CompareTo must be in consistent with equals method e.g. if two objects are equal via equals() , there compareTo() must return zero otherwise if those objects are stored in SortedSet or SortedMap they will not behave properly .

The 2 main differences are that: equals will take any Object as a parameter, but compareTo will only take Strings . equals only tells you whether they’re equal or not, but compareTo gives information on how the Strings compare lexicographically.
