I was trying to upgrade my java 1.6.0_20 to java 1.6.0_24 as a self-learning experience. Felt nervous and want to know the right way. Yes, I downloaded the file from SUN:
and executed it. It was successfully installed in my local folder
But, when I check the version it still displayed the old version which is linked the java executable by two symlinks after I recursively checked each file (for simplicity I put them directly here):
Now, my question is: can I replace the old java executable with the new one, or simply replace the whole folder that contains the java executable? I am aware there some new files. Not sure the whole story while I am trying to understand the basics.
I am using Ubuntu 10.10 Maverick Meerkat - released in October 2010 amd64-server in linux kernel 2.6.35.27-server & gnome 2.32.0.
Please someone give me a explanation. Thanks a lot!

SUNFLOW(1) SUNFLOW DOCUMENTATION SUNFLOW(1)NAME
sunflow - rendering system for photo-realistic image synthesis
SYNOPSIS
sunflow [option(s)] file(s)
DESCRIPTION
sunflow is an open source rendering system for photo-realistic image synthesis. It is written in Java and built around a flexible ray
tracing core and an extensible object-oriented design. It was created as a framework for experimenting with global illumination algorithms
and new surface shading models.
GENERAL OPTIONS
A summary of the options can be obtained by using one of the following options:
-h, -help
Display the list of available commands
PERFORMANCES
Sunflow will run considerably faster with the so called server VM (Virtual Machine). This server VM is part of Java, but it's not included
in the standard (JRE) installation of Java. The server VM starts up more slowly and uses more memory than the standard VM, but it runs a
lot faster in many cases.
Sunflow's built-in realtime raytracing benchmark (-rtbench) for example runs more than twice as fast with the server VM (exact speedup
depends on your hardware).
The easiest way to get the server VM is by installing the Java Development Kit (JDK).
On Debian, it is possible to install different JVM at the same time, amongst which: gij-4.2 (main), openjdk-6-jre (main), sun-java5-jre
(non-free), sun-java6-jre (non-free). To change the java link from one to another, use (with root privileges):
"update-alternatives --config java"
A pretty good choice should be openjdk-6-jre.
See also the "CONFIGURATION FILES" section.
SUGGESTED OPTIONS
As explained above, the following options can be used to obtain a performance gain, but depend on JVM used:
-server
Use the server virtual machine. The JDK matching the selected JVM has to be installed for this option to actually work, e.g.
sun-java5-jdk (non-free). A warning will be displayed otherwise, and this option ignored.
-XmxMEM
Use a memory upper limit of MEM instead of the default (probably 64M). Example of valid values: 512M, 1G.
Those options are best set through the SUNFLOW_JAVA_OPTIONS environment variable, or stored in the configuration files.
CONFIGURATION FILES
To allow flexible configuration, the sunflow wrapper sources two configuration files: /etc/sunflowrc and ~/.sunflowrc, in this order.
The syntax is simple "export KEY=VALUE". Lines beginning with a sharp sign are ignored.
The following options are supported:
SUNFLOW_JAVA
The java virtual machine to use. It's then possible to have e.g. a system-wide java alternative pointing to /usr/bin/gij-4.2, while
sunflow uses a different JVM, e.g. /usr/lib/jvm/java-1.5.0-sun-1.5.0.12/bin/java.
If not set (the default), java will be called, meaning the system-wide alternative will be used.
SUNFLOW_JAVA_OPTIONS
Those are the options to be passed to the java interpreter, see above for examples.
SUNFLOW_OPTIONS
The list of options to pass to sunflow automatically to avoid repeating them on each invokation of sunflow. Quotation marks are needed
if more than one option is specified.
If not set (the default), no option is passed to sunflow.
