To install Java on Ubuntu, follow these steps:

1. Open a terminal by pressing Ctrl+Alt+T or by searching for "Terminal" in the dashboard.
2. Update the package index by running the following command:

1

sudo apt update

1. Install the default JDK by running the following command:

1

sudo apt install default-jdk

This will install the latest version of the default JDK (Java Development Kit) on your system.

1. To verify that the JDK was correctly installed, run the following command:

1

java -version

This should print the version of the JDK that you have installed.

1. If you need to install a specific version of the JDK, you can do so by using the following command:

1

sudo apt install openjdk-11-jdk

This will install version 11 of the JDK. Replace "11" with the version that you want to install.

Alternatively, you can also download the JDK directly from the Oracle website and install it manually.

However, using the package manager is recommended as it ensures that the installation is smooth and that the JDK is kept up to date with security and stability updates.
