Lately, I downloaded a new version of Eclipse Kepler (Kepler Service Release 2). Before I had done so, I had the old version of Eclipse (Eclipse Helios) on my computer. After installing Eclipse Kepler, I realized that when I used Eclipse Kepler, Eclipse would not recognize certain Java code that is accepted as code now, but wasn't in the past.
For example, my Eclipse will not let me do the following:
private JList<Phrase> list_1; //Phrase is a different class I already created.
After searching on the internet, I theorized that while my Eclipse IDE is up to date, perhaps my Java SE (which I'm not certain what that is) is not up to date.
Would updating my Java SE be the solution to my problem? If so, how do I do that?
Thank you for the help!

The example you give doesn't back up your assertion that "Eclipse would
not recognize certain Java code" and that the solution is "updating my
Java SE".

In the example, likely something has changed in your environment and you
no longer have access to class Phrase.

In the second case, it's not a bad idea always to be about as up-to-date
as you can on Java. You do this by downloading the most recent JDK
(java.sun.com, Downloads, Popular Downloads, Java for Developers),
dropping it somewhere (I never much with installing it because I do not
want the Java my machine is counting on being the unknown I count on
during development) and wiring it up to my Eclipse workspace (Window ->
Preferences -> Java -> Installed JREs.

I hope this helps as I'm not sure I grok'd your question. Please push
back with more information if not.

Cheers

First of all, thanks for getting back to me. While not having access to the class "Phrase" is a good idea, this code worked when my partner used the same code on her computer (we used repositories to synchronize our code). The computer stated that JLists are not generic and thus cannot be parameterized, which does not make sense, because this works on other computers.
That's a good idea to update my Java. I just download the new JDK, but didn't realize/know how to hook it up with Eclipse.
After going to Window -> Preferences -> Java -> Installed JREs, how do you hook up the new JDK download with Eclipse?
Thanks for your help!

Click Add.
Choose Standard VM.
For JRE Home, click Directory.
Navigate to the parent directory of your new download (which you should
have unzipped, exploded, etc.).
Select it (don't double-click, just select it).
Click OK.
