Q2:

Create a class named Person in Java as follows:

1. The class must have four instance variables:
   • A string representing the name of the person
   • A floating-point number representing the weight of the person in kilograms
   • A floating-point number representing the height of the person in meters
   • A floating-point number representing the body temperature in Celsius
2. The class must have two constructors:
   • A default constructor that initializes the instance variable string with default values
   • Another constructor that initializes the instance variable with specific values passed as parameters
3. The class must have three methods:
   • computeBMI() that calculate and returns the Body Mass Index (BMI) of the person
   • celsiusToFahrenheit() that returns the temperature in Fahrenheit
   • celsiusToKelvin() that returns the temperature in Kelvin

Create another class Main that creates the objects of Person class and uses it:

4. in the main method, create an object of Person class and call it p1:
   • Initialize the object p1: name = Joe Smith, weight = 85, height = 1.8 and temperature = 37 (Hint: use the appropriate constructor)
   • • Call the method computeBMI using p1 and store the output in a variable bmi
   • • Call the method celsiusToFahrenheit using p1 and store the output in a variable fahrenheit
     • Call the method celsiusToKelvin() using p1and store the output in a variable kelvin
     • Display the information stored in all the three variables with an appropriate message.
   • A sample run of the program is provided in the screenshot below.

   • Show a screenshot of the output (if there is no screenshot of the output, the student shall get a zero mark for this question.

     Use your name instead of Joe Smith).
