java-programmer, JAVA Newbee Hi,

I have a few questions I'm hoping the group could answer for me. I'm
currently using Windows 98SE with all the latest updates running on a
Pentium III with 256M of RAM...

1) How can I tell what version of the JAVA runtime library I'm running?
2) I'd like to upgrade to the latest version of the RT (J2 V1.4.2). Will my
system support it?
3) Do I have to uninstall the previous version before upgrading? If so how
do I do this?

--
TIA,
Vic

I would check the JRW directory, usually under Program Files if it is
installed

I believe so

Yes. Try Settings/Control Panel/Add -Remove programs

System.getProperty("java.version")

Maybe.

No, you don't have to uninstall older JDKs or JREs.

simply run:
java -version

Will my system support it?

sure

You don't have to uninstall it, but if you really want to, do it through
the "Control Panel"

java-programmer >> JAVA Newbee Hi everyone,

Thanks for all your responses. I have a couple more questions...

The JAVA -Version command returns the following...

java version "1.3.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)
Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)

Under MS Internet Explorer Options->Setting->View Objects... There are two
Program Files with exactly the same name and their Status is: "Damaged";
Total Size is "None". The file name is... Java Runtime Environment
1.3.1_02.

My questions are:

1) Can I delete these Program Files from IE?
2) If so, should I delete them before upgrading to J2 V1.4.2 or after?

Thanks,
Vic
