Introduction
NetBeans is an integrated development environment (IDE) primarily used for Java development, though it also supports other languages like PHP, HTML5, and C/C++. With the release of NetBeans 12, users can harness improved performance, enhanced features, and seamless integration with various development tools. This guide provides a complete step-by-step process for installing NetBeans 12 on Ubuntu 20.04, ensuring a smooth development experience.
Prerequisites
Before diving into the installation process, it’s crucial to ensure you have met certain prerequisites:
1. Update Your System
While using Ubuntu 20.04, it is recommended to start by updating your system to ensure all packages are up-to-date. Open your terminal and type the following command:
bash
sudo apt update && sudo apt upgrade -y
This command refreshes the list of available packages and updates your system with the latest versions.
2. Install Java Development Kit (JDK)
NetBeans requires the Java Development Kit (JDK) to operate. For version 12, you can use OpenJDK 8 or later:
bash
sudo apt install openjdk-11-jdk
To verify the installation, run:
bash
java -version
You should see output confirming the version of Java installed on your system.
Downloading NetBeans 12

Step 3: Download the Package
Click the download link to obtain the NetBeans installation archive. Save this file to a location that is easy to navigate to, such as your home directory.
Extracting the NetBeans ZIP File

During the initial setup, you may need to configure settings such as:
- Java Platforms: Ensure that the correct JDK is selected.
- Plugins: Choose any additional plugins you may want to install for specific functionalities.
Verifying the Installation
After installing, it’s essential to verify that everything is working correctly.
Step 1: Open NetBeans
Upon launching, check to see if the IDE opens without issues. It should present you with a welcome screen where you can create or import projects.
Step 2: Create a Sample Project
To ensure the installation completed successfully, create a simple Java project.
- Go to File > New Project.
- Choose Java from the categories and Java Application from the projects.
- Click Next, name your project, and click Finish.
If the new project is created successfully, congratulations! You have correctly installed NetBeans.
Troubleshooting Common Issues
Despite a straightforward installation process, you may encounter some common issues. Here are some resolutions:
1. JDK Not Found
If you receive an error indicating that JDK is not found, ensure you have installed it correctly and that the Java path is set. You can check your PATH variable using:
bash
echo $JAVA_HOME
Make sure it points to your JDK installation.
2. Insufficient Permissions
If you face permission issues during installation, try using sudo to ensure you have administrative rights.
3. Slow Performance
If you find that NetBeans is running slowly, you may want to increase the memory available to the IDE by editing the netbeans.conf file, found in the etc/ directory of your NetBeans installation folder. Look for the line starting with netbeans_default_options and adjust the -J-Xmx value.
