Create the Student class with methods and attributes given in the PowerPoint. (You can call two Students equal if they have the same ID number).

Create a Graduate class (this is different from the PowerPoint which has a Masters and a Doctorate class, but let us just have one, derived from Student, and add another attribute (a String) called degree, which is either "Masters" or "Doctorate", and a boolean called thesis (meaning whether they have completed their thesis and initially set to false).

Student Class:

-studentNumber: int

+reset(String newName, int newStudentNumber):void

+getStudentNumber(): int

+setStudentNumber(int newStudentNumber): void

+writeOutput(): void

+equals(Student otherStudent): boolean

Graduate class:

Below is the correct code for the main method

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

public static void main(String[] args) {

File inFile = new File("student.in");

Scanner fileInput = null;

try {

fileInput = new Scanner(inFile);

} catch (FileNotFoundException ex) {

//Logger.getLogger(Lab10.class.getName()).log(Level.SEVERE, null, ex);

}

//input student into an ArrayList

ArrayList myList = new ArrayList();

while(fileInput.hasNext())

{ int id=fileInput.nextInt();

String name=fileInput.nextLine();

Student s=new Student(name, id);

myList.add(s);

}

System.out.println();

System.out.println("Students not sorted");

for(int i=0; i

{

myList.get(i).writeOutput();

}

Collections.sort(myList);

System.out.println();

System.out.println("Students sorted");

for(int i=0; i

{

myList.get(i).writeOutput();

}

fileInput.close();

inFile = new File("graduate.in");

try {

fileInput = new Scanner(inFile);

} catch (FileNotFoundException ex) {

//input student into an ArrayList

ArrayList myG = new ArrayList();

while(fileInput.hasNext())

{ int id=fileInput.nextInt();

String MD = fileInput.next();

String thesis = fileInput.next();

String name=fileInput.nextLine();

Graduate g=new Graduate(name, id, MD, thesis);

myG.add(g);

}

System.out.println();
