They are interface representing two types of events. For each type of event, you will have to receive with an object implementing one of the interfaces. Even if the two interfaces were completely equal in the functions declared, you would not be able to implement the second interface and register with this for the first type of event.

An ActionListener is used to listen for action events which are fired by subclasses fo AbstractButton and includes buttons checkboxes and menus (http://java.sun.com/developer/codesamples/examplets/java.awt.event/55.html)

An ItemListener is used to listen for item events which are fired by components that implement the ItemSelectable interface.These are components that maintain state -- generally on/off state for one or more items. The 1.1 AWT components that generate item events are checkboxes, checkbox menu items, choices, and lists (http://spectral.mscs.mu.edu/javadev/tutorials/TheJavaTutorial/post1.0/ui/itemlistener.html)
