47.5.6: Arrange the code to compute the total score for a student. Consider a comma-separated file that contains student names and scores such as the following: Jane Lee, 100, 98, 97, 100 Aaron X. Schmidt, 37, 42, 49, 54 Frank von Tardy, 2, 3, 10, 7 We can read the file one line at a time and use the indexOf method to get the positions of the commas. The call $$line.indexOf(",", pos)$$ gives the position of the next comma at or beyond the position pos, or -1 if there is no match. Rearrange the lines below to compute the total score for a student. Assume that each student has at least one score. Unused $$total = total + Integer.parseInt(score);$$ else $$score = line.substring(start);$$ $$score = line.substring(start, end);$$ $$int start = end + 1;$$ $$end = line.indexOf(",", start);$$ if (end == -1) $$int end = line.indexOf(",", 0);$$ $$String name = line.substring(0, end);$$ $$score = score.trim();$$ while (end != -1) { $$String score;$$ } Scores.java import java.util.Scanner; public class Scores { public static void calculateScore (String line) { int total = 0; System.out.println(name + " " + total); } public static void main(String[] args) { Scanner in = new Scanner(System.in); while (in.hasNextLine()) { calculateScore(in.nextLine()); } }
