How to install Java 8 on Kali Nethunter

Question

Guys I need to install jdk 8 for my programs to work better, many programs do not support the version higher than Java 8 so I want to install Java 8 to run better, I tried to install via apt-get, but I saw that it was removed from the Kali repository because very old. Can anyone help me how to install? When I run the command uname -m it shows me that the architecture is aarch64 can someone tell me how to install Java 8 on Nethunter for aarch64? Thanks in advance :)

Download JDK from the official website (subscription is required) or use the following command:

wget -c --header "Cookie: oraclelicense=accept-securebackup-cookie" https://download.oracle.com/otn/java/jdk/8u281-b09/89d678f2be164786b292527658ca1605/jdk-8u281-linux-x64.tar.gz?AuthParam=1614342179_659c3e77bffb9a532e2e87404c0c6647

then install it:

sudo mkdir /usr/lib/jvm
mv 'jdk-8u281-linux-x64.tar.gz?AuthParam=1614342179_659c3e77bffb9a532e2e87404c0c6647' jdk-8u281-linux-x64.tar.gz
sudo tar xvf jdk-8u281-linux-x64.tar.gz -C /usr/lib/jvm

Add java and javac to update-alternatives:

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_281/bin/java" 100
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0_281/bin/javac" 100

set jdk1.8 as default:

sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_281/bin/java

Check it:

java -version

sample output:

java version "1.8.0_281"
Java(TM) SE Runtime Environment (build 1.8.0_281-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.281-b09, mixed mode)

Solution 2

Guys I managed to solve by adding this line to my sources.list:

deb http://security.debian.org/debian-security stretch/updates main and then I ran this command:

apt-update

And then this:

apt install openjdk-8-jdk

And finally this:

sudo update-alternatives --config java

Then just choose Java 8 and that's it, Java is running :)

what does run better mean? ... what problem are you trying to solve?

It should be available in the repos. What does apt search openjdk-8 return?
