- Wind chill.
Given the temperature t (in Fahrenheit) and the wind speed v (in miles per hour), the National Weather Service defines the effective temperature (the wind chill) to be:
Write a program WindChill_YI.java that takes two double command-line arguments t and v and prints the wind chill. Use Math.pow(a, b) to compute ab.
Note: the formula is not valid if t is larger than 50 in absolute value or if v is larger than 120 or less than 3 (you may assume that the values you get are in that range).

* Problem: Both hasNext and next methods may block waiting for further input.
* hasNext() doesn't return false ever!!!! next() blocks until something is input!
* As you're reading from stdin, that'll either be when you send an EOF character (usually ^d on Unix),
* or at the end of the file if you use < style redirection.
* You cannot easily send and EOF character using the keyboard"
