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
