🛠 Downloading & Installing Java

Step 1: Check if Java is Already Installed

• Press Win + R, type cmd and press Enter.
• In the command prompt type: java -version If Java is installed, you’ll see a version number. If the version is outdated (for example lower than what your Minecraft setup requires), you’ll need to install or update.

Step 2: Download the Correct Java Version

• Visit the official Java download page (via Oracle or other trusted distributors like Adoptium).
• Make sure you select the version required for your Minecraft version (e.g., Java 21) and pick the Windows Installer version (x64 for most modern PCs).

Step 3: Install Java

• Once the .msi or .exe installer file is downloaded, double-click it to start.
• Follow the on-screen prompts: accept license terms, select install location (default is usually fine).
• After installation completes, click Close.

Step 4: Configure Java (Optional but Recommended)

• For modded Minecraft or server setups: ensure .jar files are associated with Java: some guides recommend using a small utility like Jarfix to restore the correct file association.
• Open the command prompt again and run java -version to confirm your new installation is working and shows the expected version.
