What are these called?

List<String> ids = new ArrayList<String>(sectionIDs);

( the part that is <> )

I know it's a newer java feature, I just cant think of the name.

  • its a list containing data type string, you can find more about generics in the links provided to you above "the part that is <>" its the part where you tell which data you want to be inside that list Commented Feb 8, 2010 at 13:13
  • The funny thing is, Java 5 is more than 5 years old, and to many people (myself included) generics still seem like a "newer" feature... Commented Feb 8, 2010 at 14:15
  • @Eli: That's because we're getting old. Anything invented since 1980 is "new". Commented Feb 8, 2010 at 14:33

Huh, I was going to say, "Those are letters and punctuation symbols. Can you make your question a little more specific?" But apparently a bunch of you figured out what it was he was looking for.
