public class AddStringToArrayList {
	//用反射机制
	public static void main(String[] args) throws NoSuchMethodException, SecurityException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
		ArrayList<Integer> list=new ArrayList<Integer>();
		Method method = list.getClass().getMethod("add", Object.class);
		method.invoke(list, "i am a String");
		System.out.println(list);
	}
