Call method from object in hashmap? - Vanagander - Oct 12, 2018
It's late and I'm tired so it is fully possible I'm being retarded but anyways:
I got a HashMap<Object, Object> in which I would like to call a setter method for all the object values in the map. Been trying to figure out a way to do it with replaceAll() but haven't had any success and my googling skills are a bit rusty (as in I've googled but came up empty handed), is this possible or am I being dumb?

Code
map.values().forEach(v -> v.setBlah(someValue));This should do what you need. If I've understood correctly...

Precisely, thank you!
