If you want to create a UML diagram in IntelliJ, there are two main ways to do it. You can either use the built-in tooling that comes with the IDE, or you can install a plugin. In this article, we’ll take a look at both approaches and see how they compare.

  • Go to File | New | UML Diagram
  • The IntelliJ IDEA UML Designer enables you to generate a UML diagram from your existing code
  • Select the type of diagram you want to create and click Next
  • For example, select Use Case if you want to model the functionality of your system using use cases
  • In the next dialog, specify the name and location for your diagram and click OK
  • IntelliJ IDEA will create a blank UML diagram and open it in the editor area: 5
  • To start populating your diagram, select an element in the Project tool window (on the left) and drag it onto the drawing area: 6 Alternatively, right-click an element in the project tool window and select Add to Diagram from the context menu: 7 Continue adding elements to your UML diagram until it is complete

With this plugin, you can easily create class, activity, component, and deployment diagrams. The plugin also supports reverse engineering of Java code into UML diagrams.

This plugin is very helpful for those who want to learn or understand UML concepts. It is also useful for developers who want to generate UML diagrams from their code in order to better document their work. Overall, the UML Plugin for IntelliJ IDEA Community Edition is a great tool that can be used by anyone who wants to create or understand UML diagrams.

How to Generate Class Diagram in Intellij Community Edition

If you are using Intellij Community Edition and want to generate a class diagram, there are a few easy steps you can follow. First, open up the project you want to generate the diagram for in Intellij. Then, select the “Project” tab from the menu bar and click on “Generate Module Diagram.”

This will bring up a new window where you can select which classes you want to include in your diagram. Once you have selected the desired classes, click “OK” and your class diagram will be generated!

Plantuml Intellij

Assuming you would like a blog post discussing how to use PlantUML in IntelliJ: IntelliJ is a popular Java IDE that offers a variety of features to help make development easier. One such feature is the ability to create UML diagrams using the PlantUML plugin.

PlantUML is an open-source tool that allows users to create UML diagrams from a simple textual description. The advantage of using PlantUML over other tools is that it can be integrated into many different IDEs, including IntelliJ. To create a UML diagram in IntelliJ, first install the PlantUML plugin from the JetBrains repository.

Once the plugin has been installed, you can create a new PlantUML file by going to File > New > PlantUML Diagram. In the new file, you can start by adding some basic information about your diagram, such as the title and author. Next, you can start adding shapes and connectors to your diagram.

For example, you can add a rectangle shape by typing ‘rectangle myRectangle’. Once you have added all of the shapes and connectors you want, you can generate your ULM diagram by clicking on the ‘Generate Diagram’ button in the toolbar. This will generate an image of your ULM diagram which you can then save or export for use in other documents.

Intellij Uml Plugin

IntelliJ IDEA UML Plugin Assuming you have IntelliJ IDEA installed, go to File->Settings->Plugins and click on “Browse repositories”. A search window will open.

Type “UML” in the search field and install PlantUML Integration plugin. Once installed, restart IntelliJ IDEA. Now let’s create a new project.

Go to File->New->Project and select Java from the list of available project types. Click Next. On the next screen, select Create project from template and choose Java Class Library from the list of templates.

Click Next. Name your project “uml-test” and click Finish. Once the project is created, open file and add the following code:

public class Main { public static void main(String[] args) { System.out.println(“Hello world!”);

} } Now we are ready to create our first UML diagram using IntelliJ IDEA UML plugin!

Right-click on file in Project Explorer panel and select Diagrams->Show Diagram Toolbox…. In Diagram toolbox window that opens, select Use case diagram from UML element drop-down menu (1) and click OK (2).

Can Intellij Create Uml Diagram?

Yes, IntelliJ can create UML diagrams. To do so, first select the “Diagrams” node in the Project tool window. Then, in the main toolbar, click on the “New Diagram” button and select “UML Class Diagram”.

This will open up the UML Class Diagram wizard, which will guide you through the process of creating your diagram.

How Get Uml from Intellij?

UML is a standard way to visualize the structure of software systems. It is often used by developers to communicate their designs to other stakeholders in the project, such as project managers or business analysts. IntelliJ IDEA has excellent support for UML and lets you easily generate diagrams from your code.

In this blog post, we’ll show you how to generate UML diagrams from your Java code in IntelliJ IDEA. We’ll start with a simple example, then look at some more advanced use cases. To get started, open up your Java code in IntelliJ IDEA and select the “Diagrams | Show Diagram Toolbox” action from the toolbar.

This will open up the Diagram tool window: Next, select the type of diagram you want to generate from the drop-down list. For our simple example, we’ll choose “Class Diagram”.

Then click on the “From Sources…” button: In the next dialog, select all of the classes you want to include in your diagram and click OK:

How Do You Create a Uml Diagram?

UML diagrams are a great way to visualize the relationships between different objects in your code. In order to create a UML diagram, you first need to identify the different objects that you want to include in your diagram. Once you have identified the objects, you can then start drawing out the relationships between them.

There are four main types of relationships that you can depict in a UML diagram: association, aggregation, composition, and inheritance. Association is the simplest relationship and it just means that two objects are related to each other. Aggregation is similar to association, but it indicates that one object contains another object.

Composition is a stronger relationship than aggregation and it means that one object is part of another object. Inheritance is the strongest relationship and it indicates that one object inherits from another object. Once you have identified the different types of relationships between your objects, you can start creating your UML diagram.

There are many different ways to do this, but one simple method is to use colored pencils or markers to draw lines between the different objects. You can also use software tools to create your UML diagrams; there are many different software packages available that will allow you to create professional-looking diagrams without having to do any hand-drawing yourself. regardless of how you create your UML diagrams, they can be a valuable tool for visualizing the relationships between different parts of your code.

How Do I Create a Sequence Diagram in Intellij?

Assuming you would like to create a UML sequence diagram: 1. In IntelliJ, open the project containing the code you want to visualize. 2. Navigate to Diagrams | Add Diagram | Sequence Diagram and click OK in the pop-up window.

Alternatively, select an existing diagram in the left-hand panel and click the Duplicate button (this will create a copy of the selected diagram). 3. By default, all classes from your project will be displayed on the new diagram. You can remove unnecessary classes by selecting them in the left-hand panel and clicking Remove from Diagram in the toolbar above or pressing Delete on your keyboard.

If some classes are not displayed on the diagram but you want them to be, add them manually using either of these two methods: To add a class from your project, select it in the left-hand panel and click Add to Diagram in the toolbar above or press Insert on your keyboard. The selected class will be added at point 0,0 (top left corner) of your diagram; you can then move it to any desired position.

To add a new class that is not part of your project yet, click Create Class/Object on formation toolbox or press Shift+Insertand then specify its name, stereotype (if necessary), scope (public, protected or private), visibility (public or private) and other properties as required.. After you have specified all necessary settings for this classifier shape click OK twice – first time to close New Class dialog box and second time – to close New Element dialog box.

. The created class will appear at point 0,0on your drawing surface; you can then move it to any desired position..4.

To start creating a sequence diagram simply drag elements from toolbox onto drawing surface – they will become objects with lifelines when dropped there.. Select an object shape from toolbox: .5lifeline6Activation7Class8Component9DeploymentSpecification10Interface11Node12Object13Package14Thread15Use Case16Note that some shapes cannot be inserted into others e…g interface cannot contain another interface inside etc..

This is controlled by UML specification rules… After dropping an object shape onto drawing surface its editable text field appears where you can type object’s name..


IntelliJ IDEA supports a variety of UML diagrams, including class diagrams, sequence diagrams, and state charts. To create a UML diagram in IntelliJ IDEA, you need to first select the type of diagram you want to create. You can then use the various tools in IntelliJ IDEA to add classes and relationships to your diagram.

Finally, you can export your UML diagram as an image or PDF file.
