Programming :: Which Version Of Java Should Installed On Computer?
Jul 15, 2010
I've purchased a couple of books so that I can begin to learn JAVA. Finding recent editions is very challenging, so the books I found cover JAVA 5.0. I plan to go through all of the exercises in both books. Which version of Java should I have installed on my computer?
Should I install 5.0 so that the examples from the book will work perfectly? Will I run into confusing situations or problems if I try the example exercises using Java 6?

This has probably been answered elsewhere, but I could not see it - how can I check which version of Ubunbtu I have installed and whether it is 32 or 64 bit?

If you are interested, Java SE 6 Update 24 is available. The Check Java Version link in my signature will tell you if you are up to date or not. The Update Java Version link in my signature will tell you how to obtain and install the latest version. The 32 bit version install directions are on the left side of that page and the 64 bit instructions are on the right side.
Just remember to remove the current version before installing the new one as it says in the instructions. The remove instructions are below the install instructions. Also, in Step 9 - "Now you'll want to tell the system, that there's a new Java version available." See the note below it that says if you get an error upon entering the command once, enter it a second time. I have to do that and sometimes forget. Just thought I would mention that. These instructions are already setup for version 6 update 24, but they can be modified for any update and they will work. I have been using these instructions for a couple of years and they work.

I try to install the java plugin but the java test pages show not installed. I have tried the openjdk-6-jdk package and the Oracle/Sun 1.6.0_26 version to no avail.
Is there some good instructions page someplace? I have yet to find a set of instructions that provides something clear that works.

Do Windows XP, Vista, Windows 7 and all Linux distributions have Java JRE installed so end-users don't have to install it to run Java applications?

I installed debian squeeze on an old computer that I found. (Pentium 4 3.2GHz HT) I installed from the i386 version, but now the uname command shows that its an i686. I don't find many packages that I need using apt-get. Do I need to compile each package I need from source or use dpkg to install the deb of an i386 version?
Can I use the i386 version on this computer rather than the i686 version? Will it cause a signifncant performance decreaes? (I use this computer to mostly do some reading and writing and file storage, no gaming etc.) How do I force the installer to use the i386 version?

If i just copy it there Debian tells me thati havent got the permission.

I play this game called Minecraft, and I'd like to run the server package as well, but the server is laggy as hell. I did my research, and some people were saying that one of the problems was the Java version. They recommended rolling back specifically to 1.6.0_13, but they didn't say how. So I Googled for a tutorial on how to roll back Java in Ubuntu, and got nothing. So here I am.
I also learned that you can add some extra code into a Java run command to make it run off of a specified version, so I added this to the original command I have to run my server
Code:
-version:1.6.0_13 and got "Unable to locate JRE meeting specification '1.6.0_13'". So now I'm thinking that Ubuntu didn't retain any previous versions of Java. My second question would be, where does Ubuntu keep it's versions of Java, cause I'd just download that version of Java, put it where Ubuntu keeps it, then run that command again and hope it works.

I've made a linux app that I'm porting to win32 winth MinGW and MSYS. It's a ticker app that reads then renders a text file to a pixmap (a tall single-line image), then it kind of scrolls the pixmap by drawing a part of it to a drawing_area, using gdk_draw_drawable() within a timeout handler set by g_timeout_add().
The problem is it works fine on linux (the scrolling is really smooth and that's the goal) but the win version is choppy and uses at least 90% of cpu resources (vs 15% with linux) like there is a big performance problem. And I'm not even sure that double buffering is set. Is it related to some mingw config or drawing_area stuff or gtk for win?

I have a Sun Fire X4450 running RHEL 5.3. Attached to this server via FC is a Sun StorageTek ST2540 that allows additional storage capacity. In order to administer the ST2540, a software application from Sun (CAM 6.6) has been installed. Part of the install process for this application also installs Java JDK1.6.0_12 (64-bit).
However as we use this hardware as a database server, our database software will not install properly as it requires an earlier version of Java JDK1.5.0_11 to be installed. When I try and install the older JDK rpm package, RHEL will not let me. How can I get both versions of Java installed?

I downloaded Java into my home folder instead of downloading it in my usr folder because it wouldn't let me(even when I was root user). It is present in my home folder with its own directory, but I am unsure how to use it. I downloaded Java to try to play Minecraft, but when I open then .jar file with the directory nothing happens. The actual directory contains the following
folders:bin,javaws,lib,man,plugin,copyright,licens e,a read me file, thirdpartylicensereadme, and a welcome.html file. I don't like running Minecraft with OpenJDK because it lags tremendously and it won't close, and I heard the "real Java" runs it much better.Did I download it incorrectly, if so can you tell me how?
