[Bluej-discuss] import java.util.*; - problem

[Bryan J. Higgs]

Jakub --

It's possible to have more than one Java Development Kit installed on a
system at the same time.
(Note you need the JDK, not just the JRE, the Java Runtime Environment.)

You have to tell BlueJ which JDK to use.  In the folder where the BlueJ
executable is installed, you should also see an executable called
"Select VM".  If you run that, it will list the versions of JDK it has
found, and will allow you to choose one of them.  Be sure that you
choose one that is at least at v1.5 .  Probably you should choose the
highest version number on your machine.

I see this on my Windows system.  I think it should also be the case for
other systems, but I'm not sure, not having any other systems to work on.

I hope this solves your problem!

Regards

Bryan
