(Optional) To Edit Attributes or Operations Type validateEntryStation and press Enter.Right-click the word Attributes and choose Insert Attribute from the pop-up menu.Ī one-line editor opens and displays the following information:.If it is not already selected, select the EntryStation element in the Diagram editor.Now that you have drawn and labeled the EntryStation element, you need to describe its attributes. Adds a Class element with the name EntryStation under the Model node in the Projects window.Displays the Class properties in the Properties window.Creates a public operation named EntryStation().Labels the Class element with the name EntryStation.If not already selected, select the newly added Class element by clicking it once.Note: Each time that you select an icon, you can place multiple instances of that element in the Diagram editor by clicking more than once. Deselect the icon by right-clicking anywhere in the Diagram Editor.This action places a Class element on the diagram. From the Basic section of the Modeling Palette, select the Class icon and click once in the Diagram editor.To Add and Define the Remaining Classes.(Optional) To Edit Attributes or Operations.To Add Attributes Using the Pop-Up Menu.This section contains the following procedures: ![]() This section illustrates some basic UML tasks provided by UML to model a simple application using a Class diagram. If you have not completed the use case tutorial, you can create a directory on your local system named UMLTutorial and create a Java-Platform Model UML project called UMLTutorialProject in that directory and proceed with this tutorial. This tutorial uses the UML project that is created in the UML: Creating Use Case Diagrams tutorial. You do not need to do the optional procedures to complete this tutorial successfully.Ĭreating Class Diagrams and Adding Elements ![]() If a procedure is labeled as optional, it is included to illustrate an additional task or alternate way of doing a task. Use the instructions beginning in the next section to draw your Class diagram. After you have completed the step-by-step procedures outlined in the tutorial, your Class diagram should look similar to Figure 1. The following sections describe how to create a simple Class diagram for a hypothetical banking application. Create the element representing the class.When representing a class in a UML model, you can do the following tasks: Software Needed for This Tutorialīefore you begin, download and install the following software:Ĭlasses define the attributes that are carried by each element instance and the operations that each element performs or undergoes. This tutorial assumes that your system meets the requirements specified in the Systems Requirements section of the NetBeans 6.0 Release Notes. Saving Diagrams and Updating Java Source Filesīefore you proceed, make sure you review the requirements in this section.Generating and Editing Java Source Code.Creating Class Diagrams and Adding Elements.The classes are arranged in hierarchies that share common structure and behavior and are associated with other classes. The IDE lets you graphically create diagrams that contain classes. Using the Class diagram model, you describe the static structure of the elements in your application. ![]() When you open a Class diagram, the IDE displays a specific selection of UML element icons in the Modeling Palette. This tutorial shows you various techniques for creating elements of a Class diagram and how to generate the Java source code for the diagram, The purpose of this tutorial is to introduce some of the IDE's UML Modeling Class diagram functionality and to show you various techniques for creating elements of a Class diagram.Ī Class diagram is a visual representation of an application showing its classes and the relationships between those classes. In this tutorial, you learn how to use the UML features of the IDE to create Class diagrams. This publication is applicable to NetBeans IDE 6.0 release Contributed and maintained by Cindy Castillo, Bob May
