Java Installation and Environment Setup (Windows)

To set up Java on your Windows machine, follow these steps:

Step 1: Download Java Development Kit (JDK)

1. Visit the official Oracle JDK download page.
2. Choose the correct version (latest LTS release is recommended).
3. Download the appropriate version for your operating system (Windows x64 Installer).

Step 2: Install JDK

1. Once the download is complete, run the installer.
2. Follow the installation instructions and choose the default path unless you want to specify a different installation directory.
3. After installation, the JDK and JRE will be installed on your system.

Step 3: Set Up Environment Variables

To make Java accessible from the command line, you need to set environment variables.

1. Open Environment Variables:

   • Press Windows + S and search for Environment Variables.
   • Click on Edit the system environment variables.
   • In the new window, click on Environment Variables.

2. Set JAVA_HOME:

   • In the System Variables section, click New.
   • Set the Variable Name to JAVA_HOME.
   • Set the Variable Value to the path where JDK is installed. For example: C:\Program Files\Java\jdk-17.

3. Edit PATH Variable:

   • In the System Variables section, find the Path variable and select it.
   • Click Edit, and in the new window, click New.
   • Add the path to the bin directory of the JDK installation. For example: C:\Program Files\Java\jdk-17\bin.
   • Click OK to save the changes.
