sudo tar -xvf jdk-17.0.6_linux-x64_bin.tar.gz -C /opt

Next, set up the Oracle JDK environment variables. Open the profile file:

sudo nano /etc/profile.d/jdk.sh

Add the following lines to the file:

export JAVA_HOME=/opt/jdk-17.0.6
export PATH=$JAVA_HOME/bin:$PATH

Save and exit the file. Apply the changes:

source /etc/profile.d/jdk.sh

Step 4: Verify Oracle JDK Installation

Verify the Oracle JDK installation by checking the version:
