Geek quiz of the day

Using only your brain, can you figure out what this will print?

public class Plus5{
   public static void main(String[] args){
      int i = 1;
      System.out.println( i++ + ++i );
 
      i = 1;
      System.out.println( i-- - --i );
   }
}

The code is Java, but I think you'd get the same results from i++ + ++i and i-- - --i in other languages that have those operators.
