The first step to installing Java 8 is to download the installer from the official Oracle website. Go to the following link: https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html

Step 2: Install the JDK

Once the download is complete, open the terminal and navigate to the directory where the installer package is located.

Run the following command to install the JDK:

sudo apt-get install openjdk-8-jdk

Step 3: Verify the installation

After the installation is complete, you can verify that Java 8 is correctly installed on your system by running the following command in the terminal:

java -version

You should see output similar to the following:

java version "1.8.0_xx"
Java(TM) SE Runtime Environment (build 1.8.0_xx-bxx)
Java HotSpot(TM) 64-Bit Server VM (build xx.xx-bxx, mixed mode)

Step 4: Set the JAVA_HOME environment variable

In order to run the java command from any location in the terminal, you need to set the JAVA_HOME environment variable.

Open the terminal and run the following command to find the location of the JDK installation:

sudo update-alternatives --config java

This command will give you the path where the JDK is installed.

Open the .bashrc file by running the following command:

nano ~/.bashrc

Add the following line to the file and replace the path with the path obtained from the previous command:

export JAVA_HOME=path-to-jdk

Save the changes and exit.

Run the following command to activate the changes:
