Building a Desktop Application with IntelliJ IDEA262

IntelliJ IDEA is a popular integrated development environment (IDE) used by developers to create software applications. It provides a wide range of features to help developers write code, debug errors, and manage projects.

In this tutorial, we will learn how to create a simple desktop application using IntelliJ IDEA. We will cover the following steps:
Creating a new project
Adding a main class
Writing the code
Running the application

Creating a New Project

To create a new project in IntelliJ IDEA, click on the "File" menu and select "New" > "Project". In the "New Project" dialog box, select the "Java" category and choose the "Java Application" template. Enter a name for your project and click on the "Create" button.

Adding a Main Class

Every Java application has a main class that serves as the entry point for the application. In IntelliJ IDEA, a main class is automatically created when you create a new project. The main class is named after the project and is located in the "src" folder.

Writing the Code

In the main class, we will write the code for our application. We will start by creating a new instance of the JFrame class. The JFrame class provides a basic window frame for our application.import .*;
public class Main {
public static void main(String[] args) {
JFrame frame = new JFrame();
(400, 300);
(true);
}
}

In the above code, we create a new JFrame instance and set its size to 400 pixels wide and 300 pixels high. We then set the frame to be visible.

Running the Application

To run the application, click on the "Run" menu and select "Run". IntelliJ IDEA will compile the code and run the application. The application will display a window with the title "Main".

Conclusion

In this tutorial, we learned how to create a simple desktop application using IntelliJ IDEA. We covered the steps of creating a new project, adding a main class, writing the code, and running the application. IntelliJ IDEA is a powerful IDE that can help developers create a wide range of software applications.
