Hi all, I'm studying UML in association with Java. Now, i'm not an expert in java but i know it pretty well: i can create and read programs without much troubles. I'm stucked with an exercise (i've no solution): i need to translate UML diagram into Java Code. But the diagram has a circular shape that i don't know and never saw. This is the diagram: [https://imgur.com/Jt4aUIh](https://imgur.com/Jt4aUIh) Now: Int1 is an interface, ClassX is an abstract class and ClassA implements Int... Hi, I am trying to make this all as simple as possible. I decided that going full factory or builder pattern would be overkill. The goal is SOLID clean code, I am still learning and want to get to a professional level, but I am relatively new to OOP and TypeScript.

A UML diagram is a diagram based on the UML (Unified Modeling Language) that represent visually a program/code with its main actors, roles, actions, artifacts, or classes in ordering a person to understand better and Extensibility and specialization mechanisms to extend the core concepts. Lately, I have been thinking more and more about the structure of a program I am working on. Every time I am thinking about a feature I might want to add, it's like I am hitting a wall and have to rethink everything from scratch. I know designing is mostly about tradeoffs, but I am really after creating a solid base that would be easy to extend. What I would like to see is a collection of (real-world) problems that developers faced throughout development and how they solved it. This what I im... I'm currently working on an assignment where I am supposed implement a Stack with Inheritance but I don't quite understand the instructions.. "(Implement MyStack using inheritance) In Listing 11.10, MyStack is implemented using composition. Define a new stack class that extends ArrayList. Draw the UML diagram for the classes and then implement MyStack. Write a test program that prompts the user to enter five strings and displays them in reverse order."

Uml class diagram extends. IntelliJ IDEA generates a UML diagram for classes and their dependencies. In the popup that opens, select items you need and press Enter. To extend your selection up or down while in the popup, press Shift + Up or Shift + Down respectively. I like to look towards multiple sources to understand topics better but it seems every place is explaining factories very differently. The place I first learned it explains a simple factory like some explain a factory method and a factory method like an abstract factory. Which then confused me and made me want to relearn a simple factory but it seems I could no long differentiate a simple factory and a factory method. So I tried to differentiate a factory method and a abstract factory but some a...

Hi, as a uni assignment I am creating a UML class diagram for an animal shelter. I decided that I will have an abstract class for Animal and two classes that would extend it - Dog and Cat. My problem is that I cannot think of any significant difference between them from the programming point of view, i.e. any attribute that can be applied to Dog can also be applied to Cat. &#x200B; For the record, I am aware that if I cannot think of any sensible business reason for such division I should ...

Sasha Shulgin said that we need a machine that does what he did. I don't remember his exact words, but it was to the effect of "A machine that has a catalogue of all substances, and their effects and molecular relationships, where you can click a button and it tells you the estimated effects of a new substance". This would facilitate major leaps in medicine. The machine would not always be accurate, as you can not know the actual effects until a human actually ingests the substance (which is why...

Therefore, rather than being expected to solve a logic problem, ...

UML 2 Tutorial - Class Diagram. The class diagram shows the building blocks of any object-orientated system. Class diagrams depict a static view of the model, or part of the model, describing what attributes and behavior it has rather than detailing the methods for achieving operations.

The last few days I've been thinking and searching ways about how to generate XML in a nice way. I have an XSD which extends the GraphML specification in order to draw more sophisticated diagrams (e.g. UML). The Structure is something like this (I replaced attribute values with python format placeholders) <xs:Node> <xs:Geometry height="{height}" width="{width}" x="{x}" y="{y}"/> <xs:Fill color="{color}"/> <xs:NodeLabel ...>{node_label}</y:Nod...

This is a comment on the posting "How to model inheritance in a relational database" (http://www.vertabelo.com/blog/inheritance-in-a-relational-database). The only reader comment posted on the site was "It's not as easy as lots of people think." Indeed. It isn't. The author poses a rather common modeling situation, offers three approaches to handling it, discusses some pros and cons of each approach, but doesn't seem to endorse any one of the approaches as "correct." In fact, none of them are l...

In order to accomplish some of the more intricate aspects of what I wanted to do with my new mudlib, one construct that immediately came to the forefront of "things I need" was a solid state machine framework. In simplest terms, any time you have a branch in execution (if statements, switch, etc), you've got some manner of state machine in action. However, branching very quickly becomes unwieldy. Enter finite state machines. Using this pattern, you can make extremely complex problems get broken...

Hey guys! I'm fairly new to this sub and to having a home lab in general and I found this community to be so kind and helping, I wanted to give back what I've learned.

I'm working on my masters thesis writeup and have a reasonably complex verification framework (not UVM but based on UVM ideas). This consists of a bunch of classes with parameterised types, and classes that extend those. I'd like to generate UML diagrams to describe this in the simplest way possible. I haven't drawn any UML diagrams since my undergrad more than a decade ago, so I'd prefer not to use something like draw.io to create them manually, as I'd probably make mistakes or would have to sp...

The class diagram is a diagram type in the UML modeling language. UML class diagrams are used by programmers to create visual representations of a system. Class diagrams are structure diagrams within the Unified Modeling Language, or UML for short.

In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects.

I will post my assignment, the code segments I'm having trouble with, what the program should do, and what it's doing. 1. Assignment: Part 1 – Add Shape class and inheritance (20%) The project contains a ‘Line’ class and a ‘Rectangle’ class, both of which are quite similar. Shapes are drawn by the user pressing down, dragging and then releasing the mouse cursor, which generates two sets of coordinates. You can think of these coordinates as defining a bounding box in which a shape is drawn.On...

I'm a first year 2nd semester comp sci student in my first java data structures and algorithms class.

Or for projects, we're given UML diagrams that pretty much tells us what to do. While I do understand the big picture of what's going on, there's a few things I simply don't understand whats going on outside of the stuff ...
