For example, automated teller machines typically have several use cases, including РІР‚СљDeposit Money,РІР‚Сњ РІР‚СљWithdraw MoneyРІР‚Сњ and РІР‚СљTransfer Funds.РІР‚Сњ Each use case represents a different capability that the system provides to clients. This diagram models the interactions between the systemРІР‚в„ўs external clients and the use cases of the system. The UML provides the use-case diagram to facilitate requirements gathering. The analysis phase is enormously important-you should consult the references we provide in Section 2.9 to learn more about object-oriented analysis. In our case study, the problem statement described the requirements of our elevator simulation in sufficient detail that you did not need to go through an analysis phase. These requirements guide you and your fellow developers as you design the system. You use the information gained in these meetings to compile a list of system requirements. In this phase you meet with the people who want you to build a system and with the people who will eventually use that system. This document and others are the result of the objectoriented analysis (OOA) phase. When developers begin a project, they rarely start with as detailed a problem statement as the one we provided in Section 2.9. In this section, we model the interaction between the user and our elevator simulation through the UML use-case diagram, which describes the sets of scenarios that occur between the user and the system. We have identified and honed the structure and behavior of our system. The previous eight РІР‚СљThinking About ObjectsРІР‚Сњ sections have concentrated on the elevatorsimulation model. Resize the window to see how the layout manager affects the size of the JButtons.Р”РЋ2.16 (Optional Case Study) Thinking About Objects: Use Cases As more components are added, the JPanel grows (according to the restrictions of its layout manager) to accommodate the components.

A JPanel is sized to the components it contains. Note that the SOUTH region is as tall as the buttons on buttonPanel. Line 38 uses the content paneРІР‚в„ўs default BorderLayout to add buttonPanel to the SOUTH region. Notice that the buttons are added directly to the JPanel-class JPanel does not have a content pane like an applet or a JFrame. The five JButtons in array buttons are added to the JPanel in the loop with line 35. Graphical User Interface Components: Part 1Р”Р„fter JPanel buttonPanel is created at line 27, lines 28РІР‚вЂњ29 set buttonPanelРІР‚в„ўs layout to a GridLayout of one row and five columns (there are five JButtons in array buttons). 22.8 Internet and World Wide Web Resources.22.3 Formatting and Saving Captured Media.20.8 Bit Manipulation and the Bitwise Operators.18.7 Internet and World Wide Web Resources.18.2 Loading, Displaying and Scaling Images.17.5 Establishing a Simple Client Using Stream Sockets.17.4 Establishing a Simple Server Using Stream Sockets.15.4 Thread Priorities and Thread Scheduling.15.3 Thread States: Life Cycle of a Thread.13.3 Creating a Customized Subclass of JPanel.11.5 Drawing Lines, Rectangles and Ovals.11.2 Graphics Contexts and Graphics Objects.10.21 Card Shuffling and Dealing Simulation.10.2 Fundamentals of Characters and Strings.
