Code: (Select All)

Selecting previously unselected package jdk-15.0.2.
(Reading database ... 47584 files and directories currently installed.)
Preparing to unpack .../jdk-15.0.2_linux-x64_bin.deb ...
Unpacking jdk-15.0.2 (15.0.2-1) ...

Just in 10sec. is it all done ?

I went to search for a tutorial on running concurrent java versions. I don't recall exactly how to do it off hand, but I know I've seen tutorials before (I haven't used JAVA in many years).

Anyways, I stumbled upon SDKMAN, a CLI tool which is used for managing software development kits. Here is a tutorial for running concurrent versions of java using SDKMAN.

Perhaps if you have a chance to try it you can make a review for us.

Yes Sure @fitkoh. 
But i need some more disk space for it. i think 5GB is not enough for it. already after all installation we discuss above my machine speed is loaded.

Yeah, whatever problem you're having with the disk space I would place at a high priority. I recommend you back up your work and create a support request in the private support forums.

Your logs doesn't show any errors, so it the control is returned to the user... it should be ended successfully.
You can also use the following command:

• apt install /path/to/jdk-15.0.2_linux-x64_bin.deb
  
  
  

Is the package compatible with your distro version? (ex. buster?)

If you have a graphical environment you can try a GUI tool called gdebi, it is very useful.

I recommend to use AdoptOpenJDK instead of Oracle Java to avoid issues with licensing and etc.

https://adoptopenjdk.net/installation.html#linux-pkg


Apart from that you installed JDK 15 which is neither Java 8 nor Java 9.

AdoptOpenJDK provides binaries for Java 8 up to the latest higher version of 15.
