Consider the dataProcessing.java program given. This program has many smelly code symptoms.

a) Perform a code review and list issues in the program.

b) Refactor (rewrite) the dataProcessing.java program based on your code review list above. Note that refactoring doesnt change the original intended functionality of the code.

import java.io.File; import java.io.FileNotFoundException; import java.io.PrintWriter; import java.util.Scanner; /** This program reads a file with double values, then sort the aray, and finally calculate some statistics. */ public class dataProcessing { public static void main(String[] args) throws FileNotFoundException { // Read Integer values from a file the data array data[] Scanner console = new Scanner(System.in); System.out.print("Input file: "); String inputFileName = console.next(); double[] data = new double[10]; // Construct the Scanner and PrintWriter objects for reading and writing File inputFile = new File(inputFileName); Scanner in = new Scanner(inputFile); // Read the input and write the output double total = 0; int i = 0; while (in.hasNextDouble()) { data[i] = in.nextDouble(); i++; } in.close(); // Sort the data array double temp; int size = data.length; boolean exchanged = true; for (i = 0; i < size && exchanged; i++) { exchanged = false; for (int j = size - 1; j >= i + 1; j--) { if (data[j] < data[j - 1]) { temp = data[j]; data[j] = data[j - 1]; data[j-1] = temp; exchanged = true; } } } // calculate statistics int length = data.length; double med, var, sd, mean, sum, varsum; sum = 0.0; for ( i = 0; i < length; i++) { sum += data [ i ]; } med = data [ length / 2 ]; mean = sum / (double) length; varsum = 0.0; for ( i = 0; i < length; i++) { varsum = varsum + ((data [ i ] - mean) * (data [ i ] - mean)); } var = varsum / ( length - 1 ); sd = Math.sqrt ( var ); System.out.println ("length: " + length); System.out.println ("mean: " + mean); System.out.println ("median: " + med); System.out.println ("variance: " + var); System.out.println ("standard deviation: " + sd); } }
