Answer 2

the sololearn course + generics should be enough. of course you also need to learn the android api
maybe also lambdas

Answer 3

if you make a ArrayList of int you can use ArrayList<int> and in general if you want to make one from a type T you can use ArrayList<T>. writing classes that depend on a type is generics

Answer 4
