Install Java in Windows

Install Java in Windows: Here’s a step-by-step guide to install Java on a Windows machine:

Step 1: Download Java Development Kit (JDK)

• Go to the Oracle JDK download page: Open your browser and navigate to the Oracle JDK download page.
• Select the JDK version: Choose the version you want to download (e.g., JDK 17 or JDK 11, which are popular versions).
• Download the installer: Click on the link for the Windows installer. It will typically be an .exe file.

Step 2: Install Java in Windows using JDK

• Run the installer: Once the download is complete, locate the .exe file and double-click to run it.
• Follow the installation prompts:
  • Click “Next” to start the installation.
  • Choose the installation directory (the default is usually fine).
  • Click “Next” and then “Install” to begin the installation process.

Step 3: Set up Environment Variables

• Open System Properties
  • Right-click on “This PC” or “Computer” on the desktop or in File Explorer.
  • Select “Properties.”
  • Click on “Advanced system settings.”
  • In the System Properties window, click on the “Environment Variables” button.
• Add JAVA_HOME variable:
  • In the Environment Variables window, click “New” under the “System variables” section.
  • Set the “Variable name” to JAVA_HOME.
  • Set the “Variable value” to the path of the JDK installation directory (e.g., C:\Program Files\Java\jdk-17).
  • Click “OK.”
• Update the PATH variable:
  • In the Environment Variables window, find the “Path” variable in the “System variables” section and select it.
  • Click “Edit.”
  • Click “New” and add %JAVA_HOME%\bin to the list.
  • Click “OK” to close all windows.

Step 4: Verify the Installation

• Open Command Prompt:
  • Press Win + R, type cmd, and press Enter to open Command Prompt.
• Check Java version
  • Type java -version and press Enter. You should see the version of Java you installed.
  • Type javac -version and press Enter. You should see the version of the Java compiler.

If both commands show the correct version, Java is successfully installed on your system.

Additional Steps (Optional)

• Install an IDE: Consider installing an Integrated Development Environment (IDE) like IntelliJ IDEA, Eclipse, or NetBeans to make Java development easier.

That’s it! You now have Java installed on your Windows machine.
