Are you looking to install Java on your Ubuntu system? In this step-by-step tutorial, we'll guide you through the process to set up Java on Ubuntu. Follow these simple steps to ensure a smooth installation.

Step 1: Download JDK 8
Start by downloading the JDK 8 tar.gz file from the official website. This file will be the foundation for your Java installation.

Step 2: Extract Contents
Use the 'tar' command to extract the contents of the downloaded file. Execute the command 'tar -xzvf filename.tar.gz' in your terminal to unpack the contents.

Step 3: Move Extracted Files
Create a directory for Java in /usr/local/ and move the extracted files there. Use the following commands:

sudo mkdir /usr/local/java
cd /home/akshay/Downloads/
sudo mv jdk_folder /usr/local/java/jdk_folder

Step 4: Update Alternatives
Update the alternatives for Java, Java compiler, and Java Web Start using the following commands:

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jdk_folder/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk_folder/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jdk_folder/bin/javaws" 1

Step 5: Update bashrc File
Open the .bashrc file using a text editor and add the following lines at the end:
sudo gedit ~/.bashrc

Add:
export JAVA_HOME=/usr/local/java/jdk_folder
export PATH=$PATH:$JAVA_HOME/bin

Step 6: Apply Changes
Source the .bashrc file to apply the changes:
source ~/.bashrc

Step 7: Check Java Version
java -version
