Think of it as your all-in-one coding workspace — where you can write, compile, debug, and deploy your programs easily.

Why Use NetBeans?

NetBeans is ideal for both beginners and professionals because:

• It’s free and open-source.

• It integrates well with JDK and Maven.

• It includes tools for GUI design, debugging, and profiling.

• It’s maintained by the Apache Software Foundation, ensuring regular updates.

System Requirements for Installing NetBeans on Windows 11

Before you dive into installation, let’s make sure your PC meets the requirements.

💡 Pro Tip: NetBeans requires a Java Development Kit (JDK), not just the Java Runtime Environment (JRE). Without JDK, the IDE won’t run correctly.

---

Step 1: Install the Java Development Kit (JDK)

Since NetBeans runs on Java, you must install the JDK before installing the IDE.

1. Go to Oracle or OpenJDK Website

• Visit Oracle JDK Downloads or Adoptium Temurin.

• Choose Windows x64 Installer.

2. Run the Installer

• Double-click the downloaded .exe file.

• Follow the setup wizard — accept terms, choose destination, and click Next.

3. Verify Installation

Open Command Prompt and type:

If you see a version number like java version "21.0.1", your JDK installation is successful.

---

Step 2: Download Apache NetBeans for Windows 11

Now that you’ve installed Java, it’s time to download NetBeans itself.

1. Visit the Official NetBeans Website

Go to https://netbeans.apache.org/download/.

2. Choose the Latest Version

Look for the latest stable release (e.g., NetBeans IDE 22 or newer).

3. Select Windows Installer

Click Download under the Windows section — it should download a .exe file.

---

Step 3: Run the NetBeans Installer

Once the file is downloaded, follow these steps:

1. Locate the Installer

Go to your Downloads folder and double-click Apache-NetBeans-x.x-windows.exe.

2. Follow the Setup Wizard

• Click Next to start.

• Accept the License Agreement.

• Choose the Installation Directory (default is fine).

3. Link JDK Path

The installer may ask for your JDK location. If it doesn’t auto-detect it, click Browse and select:

4. Start Installation

Click Install, and wait for the process to complete (it takes a few minutes).

5. Finish and Launch

Click Finish and check Run Apache NetBeans IDE to start immediately.

---

Step 4: Configure Environment Variables (Optional)

If NetBeans doesn’t detect your JDK, you might need to set up environment variables manually.

Steps to Add JAVA_HOME:

1. Right-click on This PC → Properties.

2. Click Advanced system settings → Environment Variables.

3. Under System variables, click New.

4. Enter:

   • Variable name: JAVA_HOME

   • Variable value: C:\Program Files\Java\jdk-XX

5. Click OK, then restart your PC.

This ensures other programs and IDEs also recognize your JDK.

---

Step 5: Launch NetBeans on Windows 11

After installation, you can launch NetBeans in several ways:

• From the Start Menu → Search “NetBeans” → Click to open.

• Or use the Desktop shortcut created automatically.

On the first run, you’ll see a Welcome Screen with tutorials and sample projects.

---

Step 6: Create Your First Project in NetBeans

Let’s test if everything is working fine.

1. Create a New Java Project

• Go to File → New Project.

• Select Java with Ant → Java Application.

• Click Next.

2. Name the Project

• Enter a name like HelloWorld.

• Choose the project location.

• Uncheck “Create Main Class” if you want to add it manually.

• Click Finish.

3. Write Your First Code

In HelloWorld.java, type:

4. Run the Program

Click the Run button (green triangle) or press Shift + F6.
You should see the output in the console.

Step 7: Install Plugins and Customize NetBeans

One of the best parts about NetBeans is its flexibility.

Adding Plugins:

• Go to Tools → Plugins.

• Browse Available Plugins tab.

• Select plugins like:

  • C/C++ Support

  • PHP Tools

  • Dark Theme (Darcula)

• Click Install.

Customizing Appearance:

• Go to Tools → Options → Fonts & Colors.

• Choose a theme and font style that suits your preference.

---

Step 8: Update NetBeans and JDK Regularly

To keep your IDE running smoothly:

• Go to Help → Check for Updates.

• Update your JDK when a new LTS version releases.

Keeping both up to date ensures compatibility and performance improvements.

Tips to Optimize NetBeans Performance

1. Increase IDE Heap Memory:

   • Edit the netbeans.conf file located in the etc folder.

   • Increase:

     netbeans_default_options="-J-Xmx2048m"


2. Disable Unused Plugins:
   Go to Tools → Plugins → Installed, and deactivate unnecessary ones.

3. Use SSD Storage:
   Running NetBeans from an SSD drastically improves performance.

4. Keep JDK and Plugins Updated:
   Outdated tools cause lag and compatibility issues.
