Modeling Interactive Multimedia Documents,with actually using blue stars in a construction project: in particular, he doesn’t yet know how to develop a blueprint suitable for a home that is to be built from blue stars. And, we still need to learn how to develop a ‘blueprint’ for a software system that is to be constructed from objects. This is the focus of Part 2 of this book.薄荷醇 发表于 2025-3-30 14:37:18
A Little Taste of Javand that seeing a sprinkling of code examples definitely helps to cement object concepts. But, objects are ‘language neutral’: what you’ll learn conceptually about objects in Part 1 of this book, and about object modeling in Part 2, could apply equally well to Java, or C++, or Ada, or Smalltalk, or a补角 发表于 2025-3-30 20:01:04

Object Interactionsher to accomplish common system goals, similar to the ants in an anthill, or the employees of a corporation, or the cells in your body. Each object has a specific structure and ‘mission’; these respective missions complement one another in accomplishing the mission of the system as a whole.Glucose 发表于 2025-3-31 01:52:49

Collections of Objects a few objects, we can afford to declare individualized reference variables for these objects: Students sl, s2, s3, perhaps, or Professors profA, profB, profC. But, at other times, individualized reference variables are impractical.不能平静 发表于 2025-3-31 09:21:55
Some Final Concepts create our own abstract data types (ADTs), also known as classes, to represent objects of arbitrary complexity, particularly when we take advantage of collections, as we did when modeling the transcript attribute of the Student class in Chapter 6. As a matter of fact, these ADTs can get pretty darn仔细检查 发表于 2025-3-31 14:57:23
The Object Modeling Process in a Nutshellam Come True’. He now knows all about the unique properties of blue stars, and appreciates why they are superior construction materials — just as we’ve learned about the unique properties of software objects as application ’construction materials’ earlier in the book. But, he is still inexperiencedforthy 发表于 2025-3-31 18:51:06

Wrapping Up Our Modeling Effortsdel of the SRS — or, so it seems! Before we embark upon implementing our class diagram as Java code in Part 3 of the book, however, we need to make sure that our model is as accurate and representative of the goal system as possible.
