How to install Netbeans 12 on Linux Mint 20

Introduction to NetBeans

NetBeans is a powerful integrated development environment (IDE) that is widely used for developing applications in Java, PHP, HTML5, C++, and more. It offers a comprehensive set of tools, which makes it an excellent choice for developers at all experience levels. As a prevalent choice among Java developers, it has gained recognition for its ease of use, extensive community support, and capability to handle large projects effectively.

In this tutorial, we will guide you through the process of installing NetBeans 12 on Linux Mint 20. This guide will cover all necessary steps, from ensuring your system is prepared for the installation to the actual setup and configuration of NetBeans to get you started on your development journey.

Prerequisites

Before diving into the installation process, it’s essential to ensure that your Linux Mint 20 system meets the necessary prerequisites:

System Requirements

1. Java Development Kit (JDK): NetBeans requires the JDK to run, so you need to have it installed on your machine. NetBeans 12 is compatible with JDK 8 or later.

2. Sufficient Memory: It is recommended to have at least 8GB of RAM for smoother performance, especially when working with large projects.

3. Disk Space: Ensure you have at least 1GB of free disk space for the installation files and additional space for your projects.

4. Internet Connection: While a stable internet connection isn’t necessary for installation, it is useful for downloading plugins and updates.

Step 1: Installing the Java Development Kit (JDK)

First, verify if you already have JDK installed on your system. Open a terminal by pressing Ctrl + Alt + T and run the following command:

bash
java -version

If the terminal returns a version number, JDK is installed. If not, follow these steps to install it:

1. Update Package Index: It’s a good practice to start by updating your existing package index:

   bash
   sudo apt update

2. Install Default JDK: Install the default version of JDK using the command below:

   bash
   sudo apt install default-jdk

3. Verify Installation: After installation, verify it again using:

   bash
   java -version

You should see the version of the JDK you just installed, confirming your successful setup.

Step 2: Downloading NetBeans

With the JDK installed, the next step is to download NetBeans 12. This can be done through the official Apache NetBeans website. Follow these steps:

1. Navigate to the Download Page: Visit the Apache NetBeans download page.

2. Select the Version: Scroll down to find NetBeans 12. You will find various options for downloading. Choose the .sh installer for Linux.

3. Download the Installer: Click on the appropriate link, and the download should start automatically.

Step 3: Preparing for Installation

Once the installer is downloaded, you’ll need to set the executable permissions. This requires using the terminal.

1. Open the Terminal: Use Ctrl + Alt + T to launch the terminal.

2. Change Directory to Downloads: Run the following command to navigate to your Downloads folder (or wherever you saved the installer):

   bash
   cd ~/Downloads

3. Set Executable Permissions: Use the following command to make the installer executable:

   bash
   chmod +x apache-netbeans-12.*.sh

Step 4: Installing NetBeans

Now it’s time to install NetBeans.

1. Run the Installer: Execute the installer with the following command:

   bash
   sudo ./apache-netbeans-12.*.sh

2. Follow Installation Steps: The installation wizard should appear. Follow the prompts on the screen, including specifying the JDK location, which is usually /usr/lib/jvm/java-11-openjdk-amd64 (change accordingly if you installed a different version).

3. Choose Installation Directory: Select or confirm the directory where you want NetBeans to be installed.

4. Complete Installation: Once you have set your preferences, the installation process will begin. Wait for it to finish, which may take a few minutes.

Step 5: Launching NetBeans

After the installation is complete, it’s time to launch NetBeans and configure it for your project needs.

1. Start NetBeans: You can launch NetBeans from the terminal by typing:

   bash
   netbeans

   Alternatively, you can find it in your applications menu.

2. Initial Configuration: When you launch it for the first time, NetBeans may prompt you to import settings from a previous installation, if applicable. You can choose to import settings or skip this step.

3. Installing Additional Plugins (Optional): NetBeans allows you to install additional plugins that can enhance your development experience. Navigate to the “Plugins” section under the “Tools” menu to explore available plugins.

Step 6: Creating Your First Project

Now that you have NetBeans up and running, let’s create a simple Java application.

1. Create a New Project: Click on “File” → “New Project”. Choose “Java” in the Categories window, and then select “Java Application” in the Projects window.

2. Specify Project Details: Enter a project name and choose a suitable location on your system to save it. Make sure that the checkbox for creating a main class is selected.

3. Write Code: You are now in the NetBeans coding environment. In the main class, you can write your Java code. For example, start with a simple “Hello, World!” program:

   java
   public class HelloWorld {
   public static void main(String[] args) {
   System.out.println(“Hello, World!”);
   }
   }

4. Run the Project: Click on the green arrow icon (Run Project) or press F6 to run your project and view the output in the output window.

Troubleshooting Common Issues

If you encounter any issues during installation or while using NetBeans, here are some common troubleshooting tips:

• Missing JDK Error: Ensure the path to the JDK is correct in the NetBeans configuration.

• Slow Performance: If NetBeans is running slowly, consider closing other applications or increasing the amount of allocated memory in the NetBeans configuration.

• Plugin Errors: If you encounter plugin issues, navigate to the “Plugins” section within the tools menu to check for updates or disable conflicting plugins.

Conclusion

With the steps outlined in this article, you are now equipped to install and start using NetBeans 12 on Linux Mint 20. This IDE will enhance your programming efficiency and provide a robust platform for developing applications. As with any tool, the best way to become proficient is through practice. Explore its features, complete a few sample projects, and continue to expand your development skills.
