Almost everything is done for this. Essentially im just changing the structure from a linked list to a binary search tree;import java.io.File; import java.io.FileWriter; import java.io.IOException; import java.util.*; public class StudentRoster { 	static int maxSize=10; 	    public static class Student {        String name;        int IDNo;        Student() {}        Student(String name, int ID) {            this.name = name;            this.IDNo = ID;        }    }    public static LinkedList readFile() {    //method to read in files        LinkedList list = new LinkedList();        try {            File file = new File("C:\Users\seanp\Desktop\studentroster.txt");  //associated path            Scanner scn = new Scanner(file);         //create new scanner object            while (scn.hasNextLine()) {           //reads in the files by each line                String data = scn.nextLine();                int i = 0;                               while (i  list) { //update array and sort        int ind = 0;        while (dataArray[ind] != null) {      //updates array contents            ind++;        }        while (list.size() > 0) {            Student student = list.removeFirst();            dataArray[ind] = student;            ind++;            if (ind == dataArray.length) {                break;            }        }        int n = ind;        //selection sort          for (int i = 0; i  list = new LinkedList();        System.out.println("1.
