Less than an hour after I posted last weeks Friday Java Non-quiz, Steve walked in, wrote some code on the white board, and said: "This should be on your Java quiz."

Here's a simplified version of his class:

1    public class Foo { 
2        public static void main(String[] args) { 
3            Foo foo = new Foo(); 
4            foo.printIt(foo.getIt()); 
5        } 
6     
7        @SuppressWarnings("unchecked") 
8        private <T> T getIt() { 
9            return (T) "hello, world."; 
10       } 
11    
12       private void printIt(String s) { 
13           System.out.println(s); 
14       } 
15   }

The question remains the same:

Q: Compile, or no compile?

Strict rules apply: No actually running the compiler. Must back answer with JSL citation.
