Task - Spring Boot - REST Controllers

[akash-coded]

Create a Spring Boot application with two controllers: HomeController and TaskController.

Create the following mappings:

• / - Displays a welcome message "Hello visitor!"
• /task - Displays the message "Task demonstration"
• /task/showMyInfo - Displays your personal info such as name, city, state, and dream_job.
• /task/showMyHobbies - Enlists your top 3 hobbies as an array.

Create appropriate handler methods in the respective controller classes.
