It's also possible to use StringTokenizer:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/StringTokenizer.html
The following example is taken from the above mentioned web page:
[The code:
     StringTokenizer st = new StringTokenizer("this is a test");
     while (st.hasMoreTokens()) {
         System.out.println(st.nextToken());
     }
 prints the following output:
     this
     is
     a
     test
]

Hopefully not adding to the confusion...
