Answer 1

Person Ho = new Person ();
Person.Hand Ha = Ho.new Hand ();
Ha.Shake ();

Also in your Shake() method, System needs to be capitalized.

Answer 2

ChaoticDawg answer is correct.

Another option is to create a method to return a Hand object from Person object.

public class Person {
private Hand hand = new Hand();

public Hand getHand() {
return hand;
}

public class Hand {
void Shake () {
System.out.println ("Hi");
}
}
}

public class Program
{
public static void main(String[] args) {
Person p = new Person();
p.getHand().Shake();
}
}
