We consider most everything to be a "subtype"
of Object.
This means that if you have a variable or field that holds an Object
you can assign any data you want into it.
~void main() {
String oak = "oak";
Object tree = oak;
System.out.println(tree);
~}If something is a subtype of Object, we would call Object
its "supertype."1
