This is my homework Assignment. I am having an issue under the stage 3. This is what I have so far. I need help with making an array for Data1.txt and Data2.txt and sorting it.

import java.util.*;

import java.io.*;

public class PersonTester extends Person

{

public static void main(String[] args) throws IOException

{

String text = null;

String a = "data1.txt";

BufferedReader brst = new BufferedReader(new FileReader(a));

text = brst.readLine();

int aSize = Integer.parseInt(text);

System.out.println(aSize);

String text2 = null;

String b = "data2.txt";

BufferedReader brst2 = new BufferedReader(new FileReader(b));

text2 = brst2.readLine();

int bSize = Integer.parseInt(text2);

System.out.println(bSize);

String[] studArray = new String[bSize];

Programming Assignment 3: Inheritance and Interface CPSC 131: Introduction to Computer Programming II (Fall 2016) Due October 31, 2017 1 Description of the Program In this assignment, you will make two classes, Student and Instructor, that inherit from a superclass Person. The implementation of class Person is given. You will also need to write a test program to test the methods you write for these two classes. The implementation details are described as follows Stage 1: In the first file Student.java, you should include the following additional instance variables and methods (other than al instance variables and methods inherited from class Person) . Private instance variables studentID, and major; . A constructor takes four inputs (name, age, studentID and major); . Two additional getter methods to return each of instance variables (accessor); . Two setter methods to change each of instance variables (mutator) . A method toString that converts a student's information into string form. The string should have the format as shown in Figure 1. You should override superclass toString) methood . A method compareTo that implements the interface Comparable, so that Student objects can be sorted by studentID in an ascending order Stage 2: In the second file Instructor.java, you should include the following additional instance variables and methods (other than all instance variables and methods inherited from class Person) Private instance variable salary; . A constructor takes three inputs (name, age, and salary); One additional getter method to return the instance variable (accessor); . One setter method to change the instance variable (mutator)
