Step 4 − The next window holds the NETBEANS IDE 18 license agreement. Read it carefully and accept the agreement by checking the checkbox at “I accept the terms in the license agreement” and then click the Next button.

Step 5 − 选择需要安装 Netbeans 18 的目标目录。此外，您还可以浏览 Java Development Kit 已安装在您的系统中的目录，并单击 Next 按钮。

Step 5 − Choose the destination directory where you need the Netbeans 18 to be installed. Furthermore, you can also browse through the directory where Java Development Kit is installed in your system and click on the Next button.

Step 6 − 选中 Check for Updates 框以自动更新，然后单击 Install 按钮开始安装。

Step 6 − Check the Check for Updates box for automatic updates and click the Install button to start the installation.

Step 7 − 之后向导将开始准备安装数据。

Step 7 − The wizard will then start preparing the installation data.

Step 8 − 此步骤将开始安装 NetBeans IDE 18 并且可能需要一段时间。

Step 8 − This step starts the installation of NetBeans IDE 18 and it may take a while.

Step 9 − 流程完成后，单击 Finish 按钮完成安装。

Step 9 − Once the process is complete, click the Finish button to finish the installation.

Step 10 − 启动 NetBeans IDE 后，您将看到如以下屏幕截图所示的开始页面。

Step 10 − Once you launch the NetBeans IDE, you will see the start page as shown in the following screenshot.

Step 11 − 在文件菜单中，选择 New Project … 以打开新建项目向导，如以下屏幕截图所示。

Step 11 − In the file menu, select New Project… to open the New project wizard as shown in the following screenshot.

Step 12 − 在 New Project 向导中，选择 Java with Ant 并单击 Next 。它会开始为您创建新的 Java 应用程序。

Step 12 − In the New Project wizard, select Java with Ant and click on Next. It starts creating a new Java Application for you.

Step 13 − 在 New Java Application 窗口中选择项目名称和项目位置，然后单击 Finish 。它将创建具有给定名称的示例应用程序。

Step 13 − Select the name of the project and location of the project in the New Java Application window and then click Finish. It creates a sample application with the given name.

在此示例中，将创建一个名称为 SampleJavaApplication 的应用程序。在此应用程序内，NetBeans IDE 将生成一个名为 SampleJavaApplication.java 的 Java 程序。如以下屏幕截图所示，此程序将在 NetBeans 源包 → samplejavaapplication 中创建。

In this instance, an application with a name SampleJavaApplication is created. Within this application, the NetBeans IDE will generate a Java program with the name SampleJavaApplication.java. As shown in the following screenshot, this program will be created inside NetBeans Source Packages → samplejavaapplication.

Step 14 − 右键单击该文件并选择 Run Project 以运行此代码，如以下屏幕截图所示。

Step 14 − Right-click on the file and select Run Project to run this code as shown in the following screenshot.

此自动创建的程序包含生成简单 JavaFX 窗口的代码，该窗口中有一个带有标签 Say ‘Hello World’ 的按钮。每次单击此按钮时，字符串 Hello World 都将显示在控制台上，如下所示。

This automatically created program contains the code which generates a simple JavaFX window having a button with the label Say ‘Hello World’ in it. Every time you click on this button, the string Hello World will be displayed on the console as shown below.
