The above code is a controller class in a Spring Boot application. It has two methods annotated with @GetMapping which maps HTTP GET requests to specific URLs.

1. The dataDisplay() method maps the /dataDisplay URL and returns a string "dataDisplay". This is typically used to display a specific page or view.

2. The showMainPage() method maps the /main URL and returns a string "main". This is used to display the main page or view of the application.

Note that the returned strings "dataDisplay" and "main" correspond to the names of the HTML templates or views that will be rendered by the application. The actual HTML templates are typically located in the src/main/resources/templates directory.
