Hi, I'm reading the interface summary for the java.util package. What do the letters mean after the names. For example, it has Collection, followed by a < sign, followed by an upper case I, followed by a > sign. On the next line down, it has Comparator with the upper case letter T between < and > symbols. Here's where I saw this. http://download.oracle.com/javase/6/docs/api/java/util/package-summary.html Thanks.
