Getting Started With the Net. Beans IDE Tutorial. Content. Using an Integrated Development Environment (IDE) for developing applications saves you time by managing windows, settings, and data. In addition, an IDE can store repetitive tasks through macros and abbreviations. Drag- and- drop features make creating graphical user interface (GUI) components or accessing databases easy, and highlighted code and debugging features alert you to errors in your code. The Net. Beans IDE is open source and is written in the Java programming language. It provides the services common to creating desktop applications - - such as window and menu management, settings storage - - and is also the first IDE to fully support JDK 6. The Net. Beans platform and IDE are free for commercial and noncommercial use, and they are supported by Sun Microsystems. This tutorial is aimed at those who are new to using IDEs, fairly new to programming, and new to the Java platform. You'll learn to create a simple desktop application with a GUI interface and functionality that calculates overtime pay using basic features of the Net. Beans IDE. This tutorial provides explanations for the code where appropriate, as well as links to the Java API and information about objects as they are introduced.

Beans environment also provides many rich features for the various Java platforms, such as Java Platform, Enterprise Edition (Java EE) and Java Platform, Micro Edition (Java ME), this article covers only Java Platform, Standard Edition (Java SE) technology, which is generally the entry point for new developers and programmers. Future tutorials will discuss more advanced features. To follow this tutorial, you need to have downloaded and installed the JDK and the Net. Beans IDE. Or you can download JDK 6 and Net. Beans 6. 1 separately to ensure that you have the latest versions. Net. Beans IDE Nuts and Bolts Because the Net. Beans IDE is open source is undergoing continual improvement, you may notice slight differences between the screen captures in this article and the latest download. This tutorial is based on Net. Beans 6. 1 and may vary slightly from later versions as they become available. Features and Tools The Net. Beans IDE has many features and tools for each of the Java platforms. Those in the following list are not limited to the Java SE platform but are useful for building, debugging, and deploying applications and applets: Source Code Editor. Syntax highlighting for Java, Java. Script, XML, HTML, CSS, JSP, IDLCustomizable fonts, colors, and keyboard shortcuts. Live parsing and error marking. Pop- up Javadoc for quick access to documentation. Advanced code completion. Automatic indentation, which is customizable. Word matching with the same initial prefixes. Navigation of current class and commonly used features. Macros and abbreviations. Goto declaration and Goto class. Matching brace highlighting. Jump. List allows you to return the cursor to previous modification. GUI Builder. Fully WYSIWYG designer with Test Form feature. Support for visual and nonvisual forms. Extensible Component Palette with preinstalled Swing and AWT components. Component Inspector showing a component's tree and properties. Automatic one- way code generation, fully customizable. Support for AWT/Swing layout managers, drag- and- drop layout customization. Powerful visual editor. Support for null layout. In- place editing of text labels of components, such as labels, buttons, and text fields. Java. Beans support, including installing, using, and customizing properties, events, and customizers. Visual Java. Bean customization - - ability to create forms from any Java. Bean classes. Connecting beans using Connection wizard. Zoom view ability. Database Support. Database schema browsing to see the tables, views, and stored procedures defined in a database. Database schema editing using wizards. Data view to see data stored in tables. SQL and DDL command execution to help you write and execute more complicated SQL or DDL commands. Migration of table definitions across databases from different vendors. Works with databases, such as My. SQL, Postgre. SQL, Oracle, IBM DB2, Microsoft SQL Server, Point. Base, Sybase, Informix, Cloudscape, Derby, and more. The Net. Beans IDE also provides full- featured refactoring tools, which allow you to rename and move classes, fields, and methods, as well as change method parameters. In addition, you get a debugger and an Ant- based project system. Getting Familiar With Net. Beans To get started, download the latest stable version from the Net. Beans. org web site and install it on whatever platform you use for programming and development. The Net. Beans. org web site lists the computer requirements needed to run the IDE. Net. Beans can automatically upgrade its core and extension modules over the Internet, and it has a module that runs periodically on your behalf to check for updates to the version of Net. Beans you're using. In addition, the Update Center can update and install any modules you okay or request. When you start the application, you should get a welcome screen similar to Figure 1. You'll notice that this welcome screen makes getting started right away an easy process by displaying a Quick Start Guide up front, as well as the options to begin a project or open one. In addition, you can select the Sample Project for a quick example of how code is set up in this IDE. Net. Beans is fairly intuitive to use, especially if you've used IDE software in the past. You'll get familiar with three concepts right away: projects, nodes, and workspaces. Within Net. Beans, you work within the context of a project, which consists of an organized group of source files and associated metadata; project- specific properties files; an Ant build script and run settings; and all the tools you'll need to write, compile, test, and debug your application. You can create a main project with subprojects, and you can link projects through dependencies. So getting started is as easy as giving your project a name. Once you tell Net. Beans the name of a new project, it then: Creates a source tree with an optional skeleton class inside. Creates a folder for unit tests. Sets classpaths for compiling, running, and testing. Sets the Java platform the project is to run on. Creates an Ant build script ( build. IDE uses when you perform commands on your project, such as compile or run. Click File from the main menu and select New Project. The New Project wizard pops up and looks similar to Figure 2. Figure 2. Notice that within the Java category, you can create a project containing an empty application. Choose Java and select Java Application. Next, name the project and select a location within your file system. Note that the IDE automatically creates a main class for your application if you want it to. Click Finish. The Projects window displays only the files that are likely to be regularly edited, such as source files and tests. To see more details about your project, click on the Files tab. The Files tab shows a directory- based view of your project, as shown in Figure 3 above. If you click on the project folder you created, you'll see that the folder contains the Ant script and properties files that control how your project is built and run: nbproject/build- impl. Contains the instructions for handling your project. The IDE generates this file, which you should not edit. Imports targets from build- impl. You can edit this file to override existing targets or create new targets. Tip: Many menu commands such as Run and Build have keyboard shortcuts to the main project. You can also access all commands for individual projects by right- clicking their project nodes in the Projects window. The Files folder also contains the output folder for compiled classes, JAR files (for Java SE projects) or WAR files (for web projects), and Javadoc. This displays as a build folder after you compile the application. Net. Beans allows you to see all your objects in a project represented as nodes of a tree, each having its own icon to represent the type of object the node represents. Within the Files tab, you can easily view the trees and representative nodes. If you double- click on a node, it opens up into a subtree that contains more detail. You can collapse or expand trees as necessary. Right- clicking on any node provides easy access to specific functions that you can perform and tools that you can use on that object. Expand the subtrees of the project node that you just created, and you will notice that the fields, constructors, methods, and bean patterns appear as node branches. The Services window lists various facilities available to your project, such as servers, databases, enterprise beans, and web services. In addition, you can see what operations have been performed and troubleshoot some types of runtime errors, such as when a remote method invocation (RMI) connection is causing a problem. You'll get more familiar with this window after you have written, compiled, run, tested and debugged your applications. Return to the Projects window. Notice the file system that has been created. Files and directories associated with an application project are organized in a logical fashion. Double- clicking a source file automatically opens the file in the workspace to the right, bringing up the appropriate Source Editor. Double- click the Main. Source Editor similar to the one in Figure 4. When your application is organized into several projects, the main project serves as the entry point to the application. Usually, the main project contains the main class that starts the application. To make a project the main project, right- click the project's node in the Projects window and choose Set Main Project. Using the Source Editor You can click right into the Source Editor and write code.
