Extract the downloaded OpenJDK 14 archive file using tar command.

tar xvf openjdk-14_linux-x64_bin.tar.gz

Move the resulting folder to /opt directory.

sudo mv jdk-14 /opt/

Configure Java environment:

sudo tee /etc/profile.d/jdk14.sh <<EOF
export JAVA_HOME=/opt/jdk-14
export PATH=\$PATH:\$JAVA_HOME/bin
EOF

Source your profile file and check java command

source /etc/profile.d/jdk14.sh

Confirm Java version.

$ echo $JAVA_HOME
/opt/jdk-14

$ java -version
