-# LAB | SpringBoot Fundamentals
-
-### Instructions
-
-1. Fork this repo.
-2. Clone your fork to your local machine.
-3. Solve the challenges.
-
-
-## Deliverables
-
-- Upon completion, add your solution to git.
-- Then commit to git and push to your repo on GitHub.
-- Make a pull request and paste the pull request link in the submission field in the Student Portal.
-
-## Tasks
-
-1. Create a Spring Boot application using Spring Initializr with the following dependencies:
-   - Spring Web
-   - Spring Boot DevTools
-
-2. Create a `GreetingController` class that has the following endpoints:
-   - `/hello` - Returns "Hello World!"
-   - `/hello/{name}` - Returns "Hello {name}!" where {name} is a path variable
-   - `/add/{num1}/{num2}` - Returns the sum of num1 and num2
-   - `/multiply/{num1}/{num2}` - Returns the product of num1 and num2
-
-3. Create a `WeatherService` class that has methods to:
-   - Get current temperature (simulate with random number between -10 and 40)
-   - Get weather condition (randomly return: "Sunny", "Rainy", "Cloudy", "Windy")
-   - Get wind speed (simulate with random number between 0 and 100)
-
-4. Create a `WeatherController` class that uses constructor injection to receive the `WeatherService` and has endpoints to:
-   - `/weather/temperature` - Returns current temperature
-   - `/weather/condition` - Returns current weather condition
-   - `/weather/wind` - Returns current wind speed
-   - `/weather/all` - Returns all weather information in a single response
-
-5. Create a `TimeService` class that has methods to:
-   - Get current time
-   - Get current date
-   - Get current day of the week
-
-6. Create a `TimeController` class that uses constructor injection to receive the `TimeService` and has endpoints to:
-   - `/time` - Returns current time
-   - `/date` - Returns current date
-   - `/day` - Returns current day of the week
-   - `/all` - Returns all time information in a single response
-
-**Remember**:
-- Use proper package structure
-- Use constructor injection instead of @Autowired
-- Test all endpoints using your web browser or Postman
-- Include appropriate error handling
-- Use meaningful variable and method names
