In this section you'll create a basic Java console app.

1. Open your command-line interface (CLI) in a directory where you want to create the project. Run the following command to create a new Gradle project.

   gradle init --dsl groovy --test-framework junit --type java-application --project-name graphtutorial --package graphtutorial

2. Once the project is created, verify that it works by running the following command to run the app in your CLI.

   ./gradlew --console plain run

   If it works, the app should output Hello World..

Before moving on, add some additional dependencies that you will use later.

• Microsoft Authentication Library (MSAL) for Java to authenticate the user and acquire access tokens.
• Microsoft Graph SDK for Java to make calls to the Microsoft Graph.
• SLF4J NOP Binding to suppress logging from MSAL.

1. Open ./build.gradle. Update the dependencies section to add those dependencies.

   :::code language="gradle" source="../demo/graphtutorial/build.gradle" id="DependenciesSnippet" highlight="7-9":::

2. Add the following to the end of ./build.gradle.

   :::code language="gradle" source="../demo/graphtutorial/build.gradle" id="StandardInputSnippet":::

The next time you build the project, Gradle will download those dependencies.

1. Open the ./src/main/java/graphtutorial/App.java file and replace its contents with the following.

   package graphtutorial;
   
   import java.util.InputMismatchException;
   import java.util.Scanner;
   
   /**
    * Graph Tutorial
    *
    */
   public class App {
       public static void main(String[] args) {
           System.out.println("Java Graph Tutorial");
           System.out.println();
   
           Scanner input = new Scanner(System.in);
   
           int choice = -1;
   
           while (choice != 0) {
               System.out.println("Please choose one of the following options:");
               System.out.println("0. Exit");
               System.out.println("1. Display access token");
               System.out.println("2. List calendar events");
   
               try {
                   choice = input.nextInt();
               } catch (InputMismatchException ex) {
                   // Skip over non-integer input
                   input.nextLine();
               }
   
               // Process user choice
               switch(choice) {
                   case 0:
                       // Exit the program
                       System.out.println("Goodbye...");
                       break;
                   case 1:
                       // Display access token
                       break;
                   case 2:
                       // List the calendar
                       break;
                   default:
                       System.out.println("Invalid choice");
               }
           }
   
           input.close();
       }
   }

   This implements a basic menu and reads the user's choice from the command line.
