To install Java on Ubuntu Linux, follow these steps:
Alternatively, you can install the specific version of Java that you want by using the following command:
sudo apt install openjdk-11-jdk
Replace "11" with the version of Java you want to install.
You can also install Java using the Oracle JDK rather than the default OpenJDK. To do this, you will need to download the Oracle JDK from the Oracle website and install it manually.
I hope this helps! Let me know if you have any questions.
