Instructions: 

Write a program that satisfies the next 8 requirements using Temperatures. Create a class similar to the Math class. Put the next 5 static methods in it. ( These static methods could also be in the Demo class.) Use the random number generator to create 3 arrays of random sizes of 1 to 5 elements. 

1. Create a static void method that has an array parameter and is called 3 times to read in Temperature values for each array.

2. Create a static method that computes and returns the average Temperature for each array and is also called 3 times.

3. Create a static method that prints the Temperatures of an array.

4. Create a static helper method that has 3 array parameters and either returns the largest array or the largest size.

5. Create a static method that returns an array of Temperatures that has the same number of elements as the largest of the three arrays. This method will have 3 array parameters and possibly an integer parameter. It determines the largest Temperature value from the three arrays at each index and creates a copy of this Temperature and stories it at that index of the new array. This array is then returned.

6. As this program is running it should generate user friendly text for input and output explaining what the program is doing. Create a set of test value Temperatures that demonstrate that your program runs correctly.
