When installing Java on Ubuntu, these points should be noted:

  1. Check if Java is installed: Run the command java -version in the terminal, and if Java is already installed, it will display the version information.
  2. Choose the appropriate Java version: Depending on your needs, you can choose either OpenJDK or Oracle JDK. OpenJDK is the version recommended by default for Ubuntu, while Oracle JDK requires manual download and installation.
  3. To install Java using a package manager: You can use the apt package manager to install Java. Run the following command to update the package list and install OpenJDK:
  4. Update the system using sudo apt and install default-jdk using sudo apt.
  5. To install Oracle JDK, you can execute the following command:
  6. Update the system, install the software-properties-common package, add the Linux Uprising Java repository, update the system again, and install the Oracle Java 14 installer package.
  7. To set up the Java environment variables: After installation, you will need to configure the JAVA_HOME and PATH environment variables. You can edit the ~/.bashrc file and add the following content at the end of the file.
  8. Define the JAVA_HOME variable as the directory path to Java, and add the Java bin directory to the PATH variable.
  9. Please replace /path/to/java with the installation path of Java.
  10. Validation of installation: After completing the installation, you can run the command java -version to verify if Java has been successfully installed.

The above are some things to note when installing Java on Ubuntu.
