Just for the fun of it try figuring out this little program:

public class InnerSpagetti {
	private int v;
	public class InnerSpagettiHelp {
		private int v;
		public InnerSpagettiHelp(int v) {
			this.v = v;
		}
		public void test() {
			System.out.println(v - InnerSpagetti.this.v);
		}
	}
	public InnerSpagetti(int v) {
		this.v = v;
	}
	public InnerSpagettiHelp setup(InnerSpagetti o) {
		return o.new InnerSpagettiHelp(v + 1);
	}
	public static void main(String[] args) {
		InnerSpagetti o1 = new InnerSpagetti(10);
		InnerSpagetti o2 = new InnerSpagetti(12);
		InnerSpagettiHelp io1 = o1.setup(o2);
		InnerSpagettiHelp io2 = o1.setup(o1);
		io1.test();
		io2.test();
	}
}
