		punkerMap.put("Sid Vicious", new Double(2332.45));
		punkerMap.put("Joe Strummer", new Double(1000.34));
		punkerMap.put("Mick Jones", new Double(345345.34));
		Set punkerSet = punkerMap.entrySet();
		Iterator i = punkerSet.iterator();
		while (i.hasNext()) {
			Map.Entry me = (Map.Entry) i.next();
			System.out.println(me.getKey() + ":" + me.getValue());
		}
		/*Sell more records and deposit money into the once bitter and disenfranchised
		youth's bank accounts*/
		double balance = ((Double) punkerMap.get("Joe Strummer")).doubleValue();
		punkerMap.put("Joe Strummer", new Double(balance + 14567.23));
