Do you understand about generics, and are just asking if the letters themselves mean anything, or do you not know what the whole angle-bracket notation is about in the first place?
If it's the former, I'd guess that E is for
, K and V are for
and [/i]value, and T is for
. But they're arbitrary -- could be any letter.
If you don't know what the angle brackets mean, they are part of something new in Java 5 called
is one place you might start to learn about this.
