Implement a runnable Class called NumericAnalyzer. Heres the functional behavior that must be implemented.
NumericAnalyzer will accept a list of 1 or more numbers as command line arguments. The provided list of numbers does not need to be ordered (although youll need to display the list of numbers sorted ascendingly).
NOTE: Dont prompt the user for input this is an exercise passing values to your program via the command line!
Error checking: if the user fails to pass in parameters, the program will display an error message (of your choice) and exit early.
The main() methods String [] args argument values must be converted and assigned to a numeric/integer array.
Your program will display the following information about the numbers provided by the user:
This list of numbers provided by the user sorted ascendingly.
The size of number list (the number of numbers!)
The average or mean value.
The median - the middle value of the set of numbers sorted. (Simple Algorithm: index = the length of the array divided by 2).
The min value.
The max value.
The sum
The range: the difference between the max and min
Variance: Subtract the mean from each value in the list. This gives you a measure of the distance of each value from the mean. Square each of these distances (and theyll all be positive values), add all of the squares together, and divide that sum by the number of values (that is, take the average of these squared values) .
Standard Deviation: is simply the square root of the variance.
Development guidelines:
The output should be neat, formatted and well organized should not hurt your eyes!
Your main() methods actions should be limited to:
gathering command line arguments
displaying error messages
creating an instance of NumericAnalyzer and invoking its top level method (e.g., calculate(), display() )
Your code should adhere to naming conventions as discussed in class.
Your implementation should embrace modularity:
Each mathematical calculation should probably be implemented by a separate method.
Yet another method should be responsible for displaying a sorted list of the numbers provided, and displaying all derived values above.
NOTE: Deriving calculations and displaying output to a Console are separate threads of responsibility, and should therefore be implemented independently of each other.
Your implementation should embrace using core Java modules:
Use the java.lang.Math Class methods to calculate square roots and perform power-to values.
the display should look like that:
10 11 11 11 12 13 14 16 17 18 18 54 55 100
Size: 14
Min: 10
Max: 100
Range: 90
Sum: 360
Mean: 25
Median: 16
Variance: 632
Standard Deviation: 25
