jdk on linux 8.0

[Dominikk Tschirky]

how do I install the j2sdk1.4.1. on Linux.
Got Linux Red Hat 8.0; or where do I install it? Install: Download it to a directory, and write a Path?
Where?
Can someone send me an answer?

You should first download the Java SDK from the Sun Java site. If you have Red Hat Linux, the best way to do this is to download the self-extracting rpm file. After downloading the self-extracting rpm file (named as *rpm.bin) you should execute it to get the .rpm file. Now do a:

rpm -ivh rpmfilename.rpm

It is also a good idea to uninstall the old versions of Java SDK before installing the JSDK 1.4. To do that use 'rpm -q' option to look for java or jsdk. Also look in rpm man pages (man rpm) to find out how to uninstall the old package.

Hallo, but with this code, where do I have to put it?

Here's what I did: Download selfextracting rpm-J2sdk1.4.1 for linux from the java.sun-Homepage.
(By the way, what's the meaning of "rpm"?)
I downloaded it to my home and I clicked on the .bin-icon.
Here's my question:
Do I have to use Emacs-Editor to write?
Do I need to save the java-files in my home too?
Where do I compile the files?
Very thankful for an answer, mfg,

Hi -
RPM stands for Red Hat Package Manager. If you double click the .bin icon then it will inflate and create another .rpm file. You have to install that running rpm -ivh filename. I do not know whether double clicking the .rpm works.
Now you can create a java source code anywhere you like. The best place may be a sub directory under your home. If your class name is MyClass then you may have to create it in MyClass.java file. You can create the source using any plain text editor - Emacs, Vi, Jedit, Jext.. or even some IDEs like Eclipse ( http://www.eclipse.org ) or JBuilder ( http://www.borland.com ). I would advise you to use some simple text editors until you are familiar with all the aspects of Java. Once you are confident, you can switch to an IDE. An IDE can reduce the typing you need to do.
Now using java thru terminal you need to compile your java program:

cd ~
(This will take you to your home directory)
cd javasrc
(this is where you created the Java code)
now do
javac MyClass.java
(a file MyClass.class will be created)
now do
java Myclass
Hope this helps.

BTW, the RPM places the jdk in /usr/java.

Hello,
I'm very glad to get this message, just one more question:
how to I install the "rpm-jdk-package" after downloaded it from Sun?
the HelloWorld is written: just there is no "javasrc"-command. It's not getting compiled. No "javac xxx.java"-command.
