Having a few more issues with my homework in debugging it all and making it work entirely.

PERSONTESTER.JAVA___

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"; Scanner read=new Scanner(new File(a)); // BufferedReader brst = new BufferedReader(new FileReader(a)); //text = brst.readLine(); int aSize = Integer.parseInt(read.nextLine()); System.out.println(aSize); Student[] students=new Student[aSize]; int i=0;

while(read.hasNext())

{

Student s=new Student(); s.name=read.next(); s.age=read.nextInt(); s.id = read.nextInt(); s.major = read.next(); students[i]=s; i++;

} sortStudents(students); System.out.println(Arrays.toString(students)); }

//Scanner in=new Scanner(new File(b)); // int bSize = Integer.parseInt(in.nextLine()); //System.out.println(bSize); //same for DATA2.txt just like data1.txt //same for data2.txt

public static void sortStudents(Student students[])

{ int size = students.length; for (int p=1; p { Student key = students[p]; int q = p-1; while (q>=0 && students[q].compareTo(key)==1) { students[q+1] = students[q]; q = q-1; } students[q+1] = key; } } }

STUDENT.JAVA____

INSTRUCTOR______

PERSON___(THIS CLASS CAN NOT CHANGE)

public class Person { private String name; private int age;

public Person() { name=""; age=0; } /** Create a person with a given name and age. @param name the name @param age the age */ public Person(String name, int age) { this.name = name; this.age = age; }
