Hello, World [5 points]
This is everyone’s first program. Write a program HelloWorld.java that, when run, displays the phrase: “Hello, World.”
% java HelloWorld Hello, World
Wind chill [8 points]
Given the temperature T (in degrees Fahrenheit) and the wind speed v (in miles per hour), the National Weather Service defines the effective temperature (the wind chill) as follows:
w = 35.74 + 0.6215 T + (0.4275 T – 35.75) v^0.16
Write a program WindChill.java that takes two double command-line arguments temperature and velocity and prints the wind chill. Use Math.pow(a,b) to compute a^b.
NOTE 1: a^b means a to the power of b.
NOTE 2: 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 (assume that the input values testing your program are in range).
NOTE 3: It is not necessary to round the wind chill value, display the value that is computed.
java WindChill 35.0 10.0 27.445420
Order check [7 points]. Write a program OrderCheck.java that takes four int command-line arguments w, x, y, and z. Define a boolean variable whose value is true if the four values are either in strictly ascending order (w < x < y < z) or strictly descending order (w x y z), and false otherwise. Then, display the boolean variable value.
NOTE 1: Do not use if statements on this program.
NOTE 2: Assume that the inputs will always be integers.
java OrderCheck 5 10 15 2 false
java OrderCheck 15 11 9 4 true
