CS 140 - Homework 1

Write a Java program that calculates the wind chill temperature W given the current temperature t and the wind velocity v. The current temperature and the wind velocity should be entered by the user. The formula the National Weather Service uses to calculate wind chill is:

W = 35.74 + 0.6215t + (0.4275t - 35.75)v^0.16

Here is an example interaction with wind chill program. Note that the answer is printed rounded to one decimal place.

   Enter temperture (F): 32
   Enter wind velocity (MPH): 10
   
   The wind chill for 32.0 degrees with a 
   wind velocity of 10.0 MPH is 23.7 degrees.

• In Java to calculate x^y use the built-in Java function Math.pow(x,y). For example, to calculate (3.14159)⁷ we can write Math.pow(3.14159,7). To calculate (a+b)^(c+d) we write Math.pow(a+b,c+d) assuming that a, b, c, d were variables that were already declared in the program.
• Make sure that your wind chill answer is only printed to one rounded decimal place. Recall that the function Math.rint() rounds a real number (double) to the closest integer.
• Place the file Program.java in a folder named HW1 in your personal folder on the T: drive (not the P: drive).
• Turn in a printout of your program at the beginning of class. Please print it in advance. Don't rely on the printer in the classroom.
