"Raw Type" Problem [message #892027]

Tue, 26 June 2012 17:24

Hi,
I just removed Eclipse Helios and installed Eclipse Indigo:
Version: Indigo Service Release 2
Build id: 20120216-1857

I imported a project that I had been working on in Helios. I use JComboBoxes in my GUI and Indigo tells me:
JComboBox is a raw type. References to generic type JComboBox<E> should be parameterized
which is ridiculous Razz

I think this has something to do with Eclipse not finding my Java ? but I don't know how to fix it Sad

If you can help me, please be very clear and detailed - I am a decent programmer but not good at setting features in a program. Sad

Thanks a lot!

It probably uses a different default JRE (see 'Installed JRE' preference
page). If you don't want to use 1.5 or higher, you can also set the
compiler compliance to 1.4 on your project's 'Java Compiler' property page.

Dani,
Thanks for your comment but using an older version of Java is not the solution I wanted. Why should Eclipse Indigo think JComboBox is a raw type when Eclipse Helios doesn't?

Moderator: can you answer my problem?

With Java 6 JCombobox does not contain type parameters, but the class JComboBox in JDK 7 does contain one type parameter. So anyhow your Eclipse Indigo is picking up your JDK 7 instead of JDK 6.

Thank you,
I just came back to admit to sheer stupidity, having finally looked at the Java 7 API and discovering that fact.
It never occurred to me that Java would feel the need to do this to JComboBox.
P.S.
There are at least two other classes that now must be parameterized JList and DefaultListModel.
