Design and implement a class called RandomArray, which has an integer array. The constructor receives the size of the array to be allocated, then populates the array with random numbers from the range 0 through the size of the array. Methods are required that return the minimum value, maximum value, average value, and a String representation of the array values. Document your design with a UML Class diagram. Create a separate driver class that prompts the user for the sample size, then instantiates a RandomArray object of that size and outputs its contents and the minimum, maximum, and average values. Hint: Obviously the minimum and maximum values will be integers, but the average will need to allow decimals. Testing: Include the output for several different test runs of various sizes, that shows the array contents with its minimum, maximum, and average values.

Transcribed Image Text:1. Design and implement a class called RandomArray, which has an integer array. The constructor receives the size of the array to be
allocated, then populates the array with random numbers from the range 0 through the size of the array. Methods are required that return
the minimum value, maximum value, average value, and a String representation of the array values. Document your design with a UML
Class diagram. Create a separate driver class that prompts the user for the sample size, then instantiates a RandomArray object of that size
and outputs its contents and the minimum, maximum, and average values.
Hint: Obviously the minimum and maximum values will be integers, but the average will need to allow decimals.
Testing: Include the output for several different test runs of various sizes, that shows the array contents with its minimum, maximum, and
average values.
