	public static void main(String[] args) {

		// create an ArrayList object
		ArrayList arrayList = new ArrayList();

		// Add elements to Arraylist
		arrayList.add(new Integer("50"));
		arrayList.add(new Integer("20"));
		arrayList.add(new Integer("5"));

		Object obj = Collections.min(arrayList);

		System.out.println("Minimum Element of Java ArrayList is : " + obj);
	}
