   1. Open IntelliJ IDEA and navigate to the Plugins settings.
   2. Search for Maven and install the plugin.
2. In IntelliJ IDEA, click Create New Project.
   1. In the New Project dialog, select Maven Archetype from the list of Generators.
   2. Select the maven-archetype-quickstart archetype. This archetype creates a standard Maven project with a directory structure for source code and unit tests.
   3. Remember to use apache archetype (template).

Catalog

specify which Maven repository you want to use in your project.

The internal Maven catalog is a default one. You can also select the local repository that is located in the .m2 directory, or you can select Maven central repository.

Your project will be created with the following directory structure:

  my-project
  ├── pom.xml
  └── src
      ├── main
      │   └── Person.java
      │       Account.java
      │       AccountManager.java    
      └── test
          └── AccountManagerTest.java
          

The src/main/java directory is where you should put your Java source code, and the src/test/java directory is where you should put your unit tests.

Maven project folder-tree

To specify the version of Maven to use, you can edit the pom.xml file and add a <version> element to the <project> element. For example:

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.example</groupId>
  <artifactId>my-project</artifactId>
  <version>3.6.3</version>
  ...
</project>

This will use version 3.6.3 of Maven for the project.

Anatomy of our first Class

This Java code defines a class named “HelloWorld” with a main method. When executed, it prints “Hello World!” to the console using the System.out.println statement.

The main method serves as the entry point for the program.

This simple program is a common introductory example, demonstrating the basic structure of a Java application and how to output text to the console.
