(Java Programming)

import java.util.*;

public class GenericsDemo {

/** * @param args */ public static void main(String[] args) { // We have no idea how many states ahead of time, so we'll use a // dynamic data structure ArrayList aFewStates = new ArrayList(); aFewStates.add("New York"); aFewStates.add("Ohio"); aFewStates.add("Nevada"); aFewStates.add("Washington"); aFewStates.add("New York"); for(String state : aFewStates) { System.out.println(state); } System.out.println(); System.out.println(); // We'll use inheritance and make this REALLY weird and powerful! // Everything in Java is an Object... right?
