3 of them all consists of caffeine.
The world major source of caffeine comes from coffee bean, from which the coffee is brewed, but of course, content of caffeine varies among types of bean and the method of brewing.
Tea is another source of caffeine, but it usually contains half of the caffeine of the coffee, depending of the strength of the brew and types (e.g. oolong or black teacontains more, but don't think the blacker the tea is the higher the content!).
Actually there are others drinks which contain caffeine, e.g. coca cola, red bull.
