Python guys are really smart, they added all kinds of methods in start only, but java is adding slowly and making hard for Java developer interviews

Great Explanation.. I am just trying to understand when we already have put method to add an entry.. why to even go for putIfPresent() ?

Is there any other specific reason for it?

What does it do is it like default one what will run if no other entry matches?? Then it will spit this thing out
