[IN JAVA] Thanks in advance for your help! I will post the mainclass and data files below the photos.
Main Class:
import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;
public class Main
{
public static Scanner keyboard = new Scanner(System.in);
public static final int MAX_CLASS_SIZE = 100;
public static void main(String [] args)
{
int num140Students;
String lastNameSearchFor;
Student [] cs140Class = new Student [MAX_CLASS_SIZE];
String fileName;
System.out.print(“Enter the class file name: “);
fileName = keyboard.next();
// fileName = “cs140Data.txt”; // might want to uncomment fortesting purposes
num140Students = loadArray(cs140Class, fileName);
System.out.println(“nPrints all students’ numbers, names, andbirthdays “);
printStudentReport(cs140Class, num140Students);
System.out.println(“nnPrints all students in class with theiraverage”);
printClassReport(cs140Class, num140Students);
System.out.println(“nnAsk user to type last name and print thestudent information and average”);
System.out.println(“If more than one with same last name it willprint them all”);
System.out.println(“If the name isn’t there, it will print – NotFound”);
System.out.print(“Enter last name: “);
lastNameSearchFor = keyboard.next();
searchAndPrintStudent(cs140Class, num140Students,lastNameSearchFor);
System.out.println(“nnSort by student number and print”);
sortClass(cs140Class, num140Students);
printStudentReport(cs140Class, num140Students);

Write a program that reads a student’s first name, last name, student’s number, month day, and year of birth and quiz grades from a file. The students are allowed to retake the quiz up to ten times. After the birth year, there is an integer that tells how many times the student took the quiz, and then the grades on each attempt are listed. Their grade on the quiz will be the average of the attempts For example Mickey Mouse 800001247 2 15 2000 5 95 85 72 68 59 Spaces separate the fields in the file. In this case, first name is Mickey, last name is Mouse, student number is 800001247 and his birthday is 2/15/2000. The five means that he attempted the quiz 5 times and the last five numbers are the grades he got on the attempts This assignment will use 3 classes that you are to create – Date, Person, and Student. Following the directions to create each class. Test each method as you write them. Take Note: Not all methods in all classes will be used, but all methods will be tested and graded Date Class Date Constructor – assigns fields to appropriate formal parameter – using the setters so error checking will occur -day: int -month: int -year: int +Date(month:int, day:int, year:int) Accessors – returns the appropriate field Setters setMonth – assigns the field to the formal parameter.
