Why Java?

Java is the most used programming language that is known for its versatility, reliability, and performance. It is the language behind many applications and platforms, including Android apps, enterprise software, and web applications. Learning Java opens various opportunities for developers, allowing them to work on a variety of projects and industries.

What is JDK?

Firstly, let's know about what JDK actually is. JDK stands for Java Development Kit. It is a software development kit used by Java developers to develop, debug, and monitor Java applications. JDK includes tools and libraries that are essential for developing Java applications.

Why do you need to install JDK?

Java JDK can be installed over the top three operating systems i.e,

• Microsoft Windows
• Linux
• macOS

JDK provides you with all the necessary tools and libraries required for Java development. Without JDK, you won't be able to compile, run, or debug your Java programs.

Download JDK on Microsoft Windows

Step 1: Download JDK

The first step in installing JDK is to download the JDK package from the official Oracle website. Make sure to select the correct version of JDK based on your operating system. Once the download is complete, proceed to the next step to install JDK. Make sure to download the latest x64 Installer of Java SE Development Kit 18.

Step 2: Install JDK

After downloading the JDK package, double-click on the installation file to start the installation process. Follow the on-screen instructions to complete the installation and make sure to choose the appropriate installation directory.

Step 3: Set Path Variables

Once the JDK is installed, you need to set the PATH variables to ensure that your system can recognize the Java commands. To do this, navigate to the System Properties in Control Panel (for Windows). Follow the command, proceed to C:\Program Files\Java\jdk- and replace {-} with your JDK version.

• Now, you need to search Environment Variables in the Task Bar and go to “Edit the system Environment Variables”. Under the Advanced section, Click on “Environment Variables”.

• Under System variables, select the “Path” variable and click on “Edit”. Click on “New” then paste the Path Address and Click on “OK”.

• Now, in the Environment Variables dialogue box, click on “New” and then under Variable name paste the address i.e. C:\Program Files\Java\jdk. Now, Click on “OK”

Step 4: Verify Installation

To verify that JDK has been installed correctly, open a command prompt (for Windows). Make sure to enter the following on-screen command. If you see the Java version displayed, congratulations! You have successfully installed JDK on your system.

Download JDK on Linux

Step 1: Download JDK

The first step in installing JDK is to download the JDK package from the official Oracle website. Make sure to select the correct version of JDK based on your operating system. Once the download is complete, proceed to the next step to install JDK. Make sure to download the latest x64 Debian Package of Java SE Development Kit 18.

Step 2: Install JDK

To install the downloaded JDK File using the terminal, and change your directory to downloads by using the following command, $ sudo dpkg -i jdk, replace {-} with your version. Now we use Debian Package Manager to configure our downloaded file for installation by typing the following screenshot provided.

Type the following commands to proceed with the installation, Open the terminal and enter $ java -- version, $ javac --version.

Step 3: Configure Environment Variable

After the installation is complete, configure environment variables to find the Location of the JDK Files, by running this command, $ sudo update-alternatives --config java. To set the environment variable, you have to use this command, $ sudo gedit /etc/environment. Later, proceed to add JAVA_HOME=” /usr/lib/jvm/jdk-{YOUR_JDK_VERSION}” and save and close the file.

Now refresh the environment file by using, $ SOURCE /etc/environment, and echo the JAVA_HOME Path by $ echo $JAVA_HOME.
