Hello I am currently running into an error in one of my java programs and cannot seem to determine why. Hopefully you can help me with this question.

Here is my program

import java.io.FileReader; import java.io.IOException; import java.nio.file.Files; import java.nio.file.Paths; import java.util.ArrayList; import java.util.Arrays; import java.util.Collection; import java.util.Collections; import java.util.List; import java.util.Scanner;

public class Student {

// static variables static String path2StuFile = "Student2017.txt"; static String path2MinFile = "Post Secondary Education.txt";

// instance attribs int studentId; String firstName; String lastName; ArrayList mins = new ArrayList<>();

public static void studIdAndReadMins(ArrayList stdList) throws IOException { ArrayList minsReadByStudId = new ArrayList<>(); minsReadByStudId = new ArrayList(Files.readAllLines(Paths.get(path2MinFile))); Scanner sc = new Scanner(new FileReader(path2MinFile)); for (Student std : stdList) { for (int i=0;i if(i!= 0){ String[] minArray = minsReadByStudId.get(i).split(" "); int minutes = Integer.parseInt(minArray[0]); int id = Integer.parseInt(minArray[1]); if (std.studentId == id) { std.mins.add(minutes); } } } }

}

public static void main(String[] args) throws IOException { ArrayList stdList = new ArrayList<>(); Scanner sc = new Scanner(new FileReader(path2StuFile)); while(sc.hasNext()){ Student stud = new Student(); String[] data = sc.nextLine().split("\\|"); stud.studentId = Integer.parseInt(data[0]); stud.firstName = data[1]; stud.lastName = data[2]; stdList.add(stud); } studIdAndReadMins(stdList); System.out.println("Sum of Minutes Read: "); System.out.println("Name MinutesRead"); for (Student std : stdList) { System.out.print(std.firstName+" "+std.lastName+"\t"); int sum = 0; for(int min:std.mins){ sum+=min; } System.out.print(sum+" "); }

}

}

Here is my errors.

Exception in thread "main" java.nio.charset.MalformedInputException: Input length = 1 at java.nio.charset.CoderResult.throwException(Unknown Source) at sun.nio.cs.StreamDecoder.implRead(Unknown Source) at sun.nio.cs.StreamDecoder.read(Unknown Source) at java.io.InputStreamReader.read(Unknown Source) at java.io.BufferedReader.fill(Unknown Source) at java.io.BufferedReader.readLine(Unknown Source) at java.io.BufferedReader.readLine(Unknown Source) at java.nio.file.Files.readAllLines(Unknown Source) at java.nio.file.Files.readAllLines(Unknown Source) at Student.studIdAndReadMins(Student.java:26) at Student.main(Student.java:63)

Here is the question i am trying to answer.

Program 1 Each year, elementary school kids must keep track of the number of minutes they read each week. This ensures that they continue progressing in their reading and become lifelong readers. In this program, you are to create an application that shows the sum total of the minutes read by each student. There are two files in which you are to read. The first one, Student2017.txt contains all the students. The second one, MinutesRead.txt contains the minutes read and the student id. You are to create a Student class that contains an ArrayList of all the minutes read for each student. The end user should be able to print out the individual minutes read by a student and the sum total of the minutes ready by a student. An example of output might be like this: ----------------------------------------------------- Sum of Minutes Read Name Minutes Read Sammy Hagger 1,203 Nick Jonas 3,435 ------------------------------------------------------ Individual Minutes Read Name Minutes Read Sammy Hagger 234 Sammy Hagger 345 Nick Jonas 948 Nick Jonas 232 ------------------------------------------------------
