If you want to use NetBeans for other languages and platforms as well, you can download the All bundle. The file name of the installer should be something like netbeans-12.5-bin-windows-x64.exe or netbeans-12.5-bin-windows-x64-all.exe, depending on the version and bundle you choose.



  • Run the installer and choose the components to install. After you download the installer, you can double-click on it to launch it. You will see a welcome screen that asks you to choose the language for the installation. After that, you will see a license agreement screen that asks you to accept the terms and conditions. Then, you will see a installation directory screen that asks you to choose the location where you want to install NetBeans IDE. You can use the default location or browse to a different one. Next, you will see a customize installation screen that asks you to choose the components that you want to install. You can use the default selection or check or uncheck the boxes according to your preferences. For example, if you don't want to install Apache Tomcat or GlassFish Server, you can uncheck them. Finally, you will see a summary screen that shows you the details of your installation. You can click on the Install button to start the installation process.



  • Verify the installation and launch the IDE. After the installation is complete, you will see a finish screen that confirms that NetBeans IDE has been installed successfully. You can click on the Finish button to exit the installer. You can also check the box that says "Start NetBeans IDE 12.5 after installation" if you want to launch the IDE immediately. Alternatively, you can launch the IDE later by clicking on the NetBeans icon on your desktop or in your Start menu.



Congratulations! You have successfully downloaded and installed NetBeans IDE on Windows.


Creating a simple Java project




To create a simple Java project using NetBeans IDE, you need to follow these steps:


  • Create a new Java project using the wizard. After you launch NetBeans IDE, you will see a start page that welcomes you and gives you some tips and links. You can close this page by clicking on the X button in the top right corner. Then, you will see the main window of NetBeans IDE, which consists of several panels and menus. To create a new Java project, you can go to File > New Project or click on the New Project icon in the toolbar. This will open a new project wizard that guides you through the process of creating a new project. In the first step, you need to choose the project category and type. For example, if you want to create a simple Java application, you can choose Java with Ant > Java Application. In the second step, you need to name your project and choose its location and folder. For example, if you want to name your project HelloWorld, you can enter HelloWorld in the Project Name field and use the default location and folder or browse to a different one. You can also check or uncheck some options such as creating a main class or setting a project as main project. In the third step, depending on your project type, you may need to choose some additional settings such as platform, source level, libraries, etc. For example, if you are creating a Java application, you can choose Java Platform > JDK 17 as your platform and Source/Binary Format > JDK 17 as your source level. After that, you can click on Finish button to create your project.



Understand the project structure and files. After you create your project, you will see it in the Projects window in NetBeans IDE. The Projects window shows you the structure and files of your project in a tree view. You can expand or collapse each node by clicking on it or using the plus or minus signs next to it. For example, if you created a Java application named HelloWorld, you will see something like this:


HelloWorld + Source Packages + helloworld - HelloWorld.java + Test Packages + Libraries - JDK


The Source Packages node contains the source code files of your project, organized in packages. The Test Packages node contains the test code files of your project, organized in packages. The Libraries node contains the libraries that your project depends on, such as the Java Development Kit (JDK). The HelloWorld.java file is the main class of your project, which contains the main method that runs when you execute your project. You can double-click on any file to open it in the code editor.


  • Configure the project properties and classpath. You can modify the properties and settings of your project by right-clicking on the project node and choosing Properties. This will open a project properties dialog that allows you to change various aspects of your project, such as sources, libraries, run, build, etc. For example, if you want to add a new library to your project, you can go to Libraries > Add Library and choose from the available libraries or browse to a custom one. If you want to change the main class of your project, you can go to Run > Main Class and select or browse to a different class. You can also change the classpath of your project, which is the list of directories and files that the Java compiler and runtime use to find classes and resources. You can go to Sources > Source/Binary Format and choose a different source level or binary format for your project. You can also go to Libraries > Compile or Run and add or remove classpath elements for compiling or running your project.

Writing and running Java code




To write and run Java code using NetBeans IDE, you need to follow these steps:


Create a new Java class and write some code. After you create your Java project, you can create a new Java class by right-clicking on the package node where you want to create the class and choosing New > Java Class. This will open a new Java class wizard that asks you to enter the name and package of the class, as well as some options such as modifiers, superclass, interfaces, etc. For example, if you want to create a new class named Greeting in the helloworld package, you can enter Greeting in the Class Name field and helloworld in the Package field. You can also check or uncheck some options such as public modifier or main method. After that, you can click on Finish button to create your class. You will see your new class in the Projects window and in the code editor. You can write some code in your class using the code editor features such as syntax highlighting, code completion, refactoring, etc. For example, if you want to write a simple method that prints "Hello World" to the console, you can write something like this:


package helloworld; public class Greeting public void sayHello() System.out.println("Hello World");


Compile and run the Java application using the IDE. After you write some code in your Java class, you can compile and run your Java application using NetBeans IDE. To compile your application, you can go to Run > Build Project or click on the Build Project icon in the toolbar. This will compile your source code files into bytecode files and store them in a build folder in your project directory. You will see a message in the Output window that shows you the result of the compilation process. To run your application, you can go to Run > Run Project or click on the Run Project icon in the toolbar. This will execute your main class using the Java runtime environment and show you the output in the Output window. For example, if you run your HelloWorld project with the Greeting class as the main class, you will see something like this:


run: Hello World BUILD SUCCESSFUL (total time: 0 seconds)
