From the terminal, how should I install JDK?
In this guide it says to use this command:
sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk
But on Suns website, it says JDK includes the JRE, so why the JRE in the line above?
Anybody know how to actually install Java?
Every guide and every forum shows different ways of doing it.
BTW: It is a VPS (virtual private server)
Thanks

I have a java application that has an icon in the tray of the menu bar at the top of OSX. I've been able to remove the icon from the dock when the application is "minimized to tray", but it still appears when I command-tab to switch between my running applications. I'd like to hide it from there too, but I'm not sure how to do that, so I would appreciate any advice
Thanks!

Currently, I am running Mint Linux (Release 9). I need to downgrade Java from version 1.6 to 1.5, and have been trying to figure out how to go about this. So far, I've had no luck. The package manager doesn't seem to have it.

Is it possible to force java to make you catch RuntimeExceptions? Specifically I am working with the Spring framework and the whole Exception hierarchy is based upon RuntimeExceptions. A lot of the times I forget to try and catch the Exceptions. A specific example is when doing an LDAP query, or an SQL call.
Is there a way to manage the window z-ordering of JDialog windows within java?
I would like to able to assign each window to a layer such that windows on lower layers can never go above and obscure windows on higher layers. Even when they have focus. Similar to the Z-order capability that exists for components but for JDialog windows.
The solution does not need to work across all OSes. A linux specific solution is acceptable.

Hi there,
I created a program that contains linked lists that are passed various methods. While this works just fine in Java... a style checker program we have to use doesn't like it
It says: Declaring variables, return values or parameters of
type 'LinkedList' is not allowed.
If I declare them as simply List then I don't have access to the methods I want. What should I do?
