In order to install NetBeans on your system, you need to first install the Java Development Kit (JDK) and then the NetBeans IDE.
Reference: https://www.uvm.edu/it/kb/article/netbeans-setup
We can download the JDK directly from Oracle at the following URL: https://www.oracle.com/technetwork/java/javase/downloads/ At that URL, please choose the Download button as shown below:
Once you accept the License Agreement radio button, as shown below, please click the appropriate download link for your operating system:
After the JDK finishes downloading, please run the installer, and then click through all the prompts to install the JDK. Once it finishes, it will show the "Install Succeeded" dialog box as seen below:
As with the JDK, we need to download and install the NetBeans IDE. Let's start by going to https://netbeans.apache.org/download/ and downloading the latest verion of the NetBeans IDE as shown below:
You can then double-click the executable on Windows or the package on MacOS and install NetBeans by going through the installer and choosing all the default options. Once it finishes successfully, it will display the following dialog box:
This document presents a step-by-step guide that illustrates how to use the NetBeans IDE to develop a Java application. The screen shots in this document should be very close to the ones you see but might be slightly different due to different versions. In that case, the procedures listed below and the screens you see will most likely be somewhat different, but should still be close to what follows.
First of all, you should create a directory which will contain your Java project files. You can use Windows Explorer to create directories. If you are using an FSU computer, then it may be best to create your project directory on your own flash drive.
Start by choosing File → New Project… and, as shown on the screen below, please select "Java with Ant" from the Categories column and "Java Application" from the Projects category and click Next:
The first time you do this, you might have to "Accept and Install" the appropriate plugin but on subsequent runs it should work without interruption.
