**What is Java?**

**Java** is a high-level, object-oriented programming language known for its **"Write Once, Run Anywhere" (WORA)** capability. It is widely used for building web applications, enterprise software, mobile apps (Android), backend systems, and more. Java runs on the **Java Virtual Machine (JVM)**, making it platform-independent. It features automatic memory management (garbage collection), strong security, and multithreading support, making it a popular choice for scalable and robust applications.

**Java download page** will open. Click on the **JDK 23** option or the latest available version to download the Java Development Kit (JDK).

Then, click on the **Linux** option to download the JDK for your Linux Operating System.

Click on the link for the **x64 Debian Package** to download the JDK for Debian-based systems with an **x86_64 (64-bit) processor**.

**Note:** Click on the **ARM64 RPM Package** if your system has an **ARM64 processor**, such as those found in some Linux-based ARM devices.

**What is the difference between the x64 Debian Package and the ARM64 RPM Package for JDK?**

The **x64 Debian Package** is designed for **Debian-based Linux distributions** (such as Ubuntu, Debian) running on **x86_64 (64-bit) processors**. It uses the `.deb` package format and can be installed using `dpkg` or `apt`.

The **ARM64 RPM Package** is meant for **RPM-based Linux distributions** (such as RHEL, Fedora, CentOS) running on **ARM64 architecture**. It uses the `.rpm` package format and is installed using package managers like `dnf` or `yum`.

Choosing the correct package ensures compatibility with your system's architecture and package management system.

To view the **Troubleshoot Guides**, scroll down to the **Release Information** section, and click on the **Installation Instructions** link.

**JDK Installation Guide** page will open, click on the **Installation of the JDK on Linux Platforms** from the left bar

Here you can view all the Installation Information for the Linux Platforms

Scroll down to the **General Notes** section on the page. Here, you can view important information and notes about installing the JDK on **Linux platforms**, including system root access, installation steps, and additional configurations.

Scroll down to the **Downloading the JDK Installer** section. Here, you can find instructions for all available **download files** for Linux platforms, including **Debian (.deb), RPM (.rpm), and tar.gz** packages, along with guidance on how to install them.

After installing the required JDK file on your **Linux platform**, open the **terminal** and type the following command to check and view the latest installed Java version:

`java --version`

This will display the installed Java version along with other details.

Type the command **[[jshell --version]]** to view the latest jshell version installed on your Linux

**What is JShell?**

**JShell** is an interactive **REPL (Read-Eval-Print Loop) tool** introduced in Java 9. It allows developers to quickly run and test Java code **without needing to compile a full program**. With JShell, you can enter Java statements, expressions, and methods interactively, making it useful for testing, debugging, and learning Java. It provides instant feedback, helping developers experiment with Java code more efficiently.

Congratulations on completing this lab and successfully installing Java on your Linux!
