Answer 1

But this is possible:

fruit.add("Apple");
fruit.add("12311");

Answer 2

Its possible without inferring generics

var array = new ArrayList();

or

var array = new ArrayList<Object>();

also you can make an subimplementation to provide methods getting back with right values.... maybe with Optional class. Explore it!!
