Why You Need Java and NetBeans

• Java: A programming language that translates human-readable instructions into machine code (0s and 1s).
• NetBeans: An Integrated Development Environment (IDE) that simplifies writing, running, and managing Java projects.

Step 1: Install Java

1. Download Java:
   • Open a web browser (e.g., Chrome) and search for “Oracle Java.”
   • Visit the official Oracle website and navigate to the download section.
   • Download the latest Java Development Kit (JDK) version (e.g., 22.0.1) for Windows.
2. Install Java:
   • Open the downloaded .exe file and follow the prompts.
   • The JDK will also include the Java Runtime Environment (JRE).
3. Set the Path Environment Variable:
   • Locate the installed Java folder, typically under C:\Program Files\Java\JDK22\bin.
   • Copy this path.
   • Search for “Environment Variables” in the Start menu and open the settings.
   • Under System Variables, find Path, click Edit, and add the copied path.
4. Verify Installation:
   • Open Command Prompt and type: java --version
   • If the version appears, Java is installed successfully.

Step 2: Install NetBeans

1. Download NetBeans:
   • Search for “NetBeans” in your web browser.
   • Visit the official NetBeans website and download the latest version (e.g., NetBeans 22).
   • Choose the Windows 64-bit .exe installer.
2. Install NetBeans:
   • Open the downloaded .exe file.
   • By default, the installer includes modules for Java and web development. Leave the settings as they are and click Next.
   • The installer will automatically detect the Java path from Step 1.
3. Finish Installation:
   • Follow the prompts, accept the license agreement, and complete the installation.
   • Once done, launch NetBeans from the desktop shortcut.
