Install JDK from tar.gz Ubuntu

installJdkTarGzUbuntu.sh

#Login as root
sudo su

#create jdk directory
mkdir /opt/jdk

#uncompress, change to your file name
tar -zxf jdk-8u5-linux-x64.tar.gz -C /opt/jdk

#check if files are there
#ls /opt/jdk

#update alternatives so the command java point to the new jdk 
update-alternatives --install /usr/bin/java java /opt/jdk/jdk1.8.0_05/bin/java 100


#update alternatives so the command javac point to the new jdk 
update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_05/bin/javac 100

#check if java command is pointing to " link currently points to /opt/jdk/jdk1.8.0_05/bin/java"
update-alternatives --display java

#check if java command is pointing to " link currently points to /opt/jdk/jdk1.8.0_05/bin/javac"
update-alternatives --display javac

#check if java is running
java -version

Thanks, this is what I ended up doing last night, i did as the root user and you can copy and paste this block

sudo apt install wget -y # in case you do not have wget
wget https://github.com/ibmruntimes/semeru11-binaries/releases/download/jdk-11.0.22%2B7_openj9-0.43.0/ibm-semeru-open-jdk_x64_linux_11.0.22_7_openj9-0.43.0.tar.gz
tar -xzvf ibm-semeru-open-jdk_x64_linux_11.0.22_7_openj9-0.43.0.tar.gz -C /usr/local/bin
mv /usr/local/bin/jdk-11.0.22+7 /usr/local/bin/java
sudo cat >> /etc/environment << EOF
PATH="$PATH:/usr/local/bin/java/bin"
EOF
source /etc/environment
java -version

This will show something like

openjdk version "11.0.22" 2024-01-16
IBM Semeru Runtime Open Edition 11.0.22.0 (build 11.0.22+7)
Eclipse OpenJ9 VM 11.0.22.0 (build openj9-0.43.0, JRE 11 Linux amd64-64-Bit Compressed References 20240131_966 (JIT enabled, AOT enabled)
OpenJ9   - 2c3d78b48
OMR      - ea8124dbc
JCL      - 7876cac747 based on jdk-11.0.22+7)

The reason why I did this command mv /usr/local/bin/jdk-11.0.22+7 /usr/local/bin/java so we do not have the java version number hard coded in the directory. this way later on if you update the java by laying down new files in /usr/local/bin/java you do not have to update the path again that I set in /etc/environment

• download open jdk from https://www.openlogic.com/openjdk-downloads?field_java_parent_version_target_id=416&field_operating_system_target_id=426&field_architecture_target_id=391&field_java_package_target_id=396
• move tar.gz file to /opt/
• then run

cd /opt/ && \
tar xzf openlogic-openjdk-8u392-b08-linux-x64.tar.gz && \
cd /opt/openlogic-openjdk-8u392-b08-linux-x64/ && \
update-alternatives --install /usr/bin/java java /opt/openlogic-openjdk-8u392-b08-linux-x64/bin/java 2 && \
update-alternatives --install /usr/bin/jar jar /opt/openlogic-openjdk-8u392-b08-linux-x64/bin/jar 2 && \
update-alternatives --install /usr/bin/javac javac /opt/openlogic-openjdk-8u392-b08-linux-x64/bin/javac 2 && \
update-alternatives --set jar /opt/openlogic-openjdk-8u392-b08-linux-x64/bin/jar && \
update-alternatives --set javac /opt/openlogic-openjdk-8u392-b08-linux-x64/bin/javac && \
echo "export JAVA_HOME=/opt/openlogic-openjdk-8u392-b08-linux-x64" >> ~/.bashrc && \
echo "export JRE_HOME=/opt/openlogic-openjdk-8u392-b08-linux-x64/jre" >> ~/.bashrc && \
echo "export PATH=$PATH:/opt/openlogic-openjdk-8u392-b08-linux-x64/bin:/opt/openlogic-openjdk-8u392-b08-linux-x64/jre/bin" >> ~/.bashrc

• refresh with: source ~/.bashrc
• test: java -version

openjdk version "1.8.0_392-392"

Thank You. Work for me

Thank you!
