The attached program contains an array of survey responses that are hard-coded into the program. Suppose we wish to process survey results that are stored in a file. This exercise requires two separate programs. First, create an application that prompts the user for survey responses and outputs each response to a file. Use a Formatter to create a file called numbers.txt. Each integer should be written using the method format. Then modify the attached program to read the survey responses from numbers.txt. The responses should be read from the file by using a Scanner. Use method nextInt to input one integer at a time from the file. The program should continue to read responses until it reaches the end of the file. The results should be output to the text file "output.txt".

// Fig. 7.8: StudentPoll.java // Poll analysis program.

public class StudentPoll { public static void main(String[] args) { // student response array (more typically, input at runtime) int[] responses = {1, 2, 5, 4, 3, 5, 2, 1, 3, 3, 1, 4, 3, 3, 3, 2, 3, 3, 2, 14}; int[] frequency = new int[6]; // array of frequency counters

// for each answer, select responses element and use that value // as frequency index to determine element to increment for (int answer = 0; answer < responses.length; answer++) { try { ++frequency[responses[answer]]; } catch (ArrayIndexOutOfBoundsException e) { System.out.println(e); // invokes toString method System.out.printf(" responses[%d] = %d%n%n", answer, responses[answer]); } }

System.out.printf("%s%10s%n", "Rating", "Frequency"); // output each array element's value for (int rating = 1; rating < frequency.length; rating++) { System.out.printf("%6d%10d%n", rating, frequency[rating]); } } }
