Pahingi ng java grading system full . Thank you

Code:

if (stuAverage > stuAverage2 ){
        System.out.println(student + " has the highest grade of all students entered!");
    }
    else if (stuAverage2> stuAverage){
        System.out.println(student2 + " has the highest grade of all students entered!!");
    }

The Main class:

Code:

public class Main2 {

    int stuAverage;
    static String student;
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        Students stu2 = new Students();
        String grade;
        int[] answers;
        int[] correct;
        System.out.println("Enter student's name.");
        student = input.next();
        System.out.println();
        System.out.println("How many questions would you like to ask?");
        int num = input.nextInt(); // get the number of times to ask
        answers = new int[num]; // student's answers
        correct = new int[num]; // for teachers
        for (int x = 0; x < num; x++) {
            System.out.println("Enter the answer for question number: "
                    + (x + 1) + ".");
            correct[x] = input.nextInt();
        }
        System.out.println("Now for the students.");
        for (int x = 0; x < num; x++) {
            System.out.println("Enter the student answer.");
            answers[x] = input.nextInt();
        }
        int average = 0; // his/her grade
        for (int x = 0; x < num; x++){
            if (correct[x] == answers[x]){
                average++;
            }
        }
        average = (int) (((double) average) / ((double) num) * 100);
        if (average >= 90 && average <= 100)
            grade = "A";
        else if (average >= 80 && average <= 89)
            grade = "B";
        else if (average >= 70 && average <= 79)
            grade = "C";
        else if (average >= 60 && average <= 69)
            grade = "D";
        else
            grade = "F";
        int stuAverage;
        stuAverage = average;
        stu2.forMutipleStu();
    }
}

The students class to run a second student

Code:

public void forMutipleStu(){
    Scanner input = new Scanner(System.in);
    String grade2;
    int [] answers2;
    int[] correct2;
    String student2;
    System.out.println("Enter student's name.");
    student2 = input.next();
    System.out.println("A=1, B=2, C=3, D=4");
    System.out.println("How many questions would you like to ask?");
    int num2 = input.nextInt(); // get the number of times to ask
    answers2 = new int[num2]; // student's answers
    correct2 = new int[num2]; // for teachers
    for (int x = 0; x < num2; x++){
        System.out.println("Enter the answer for question number: " + (x+1) + ".");
        correct2 [x] = input.nextInt();
    }
    System.out.println("Now for the students.");
    for (int x = 0; x < num2; x++){
        System.out.println("Enter the student answer.");
        answers2[x] = input.nextInt();
    }
    int average2 = 0; // his/her grade
    for (int x = 0; x < num2; x++){
        if (correct2[x] == answers2[x]){
            average2++;   
        }
    }
    average2 = (int) (((double)average2)/ ((double)num2) * 100);
    if (average2 >= 90 && average2 <= 100)

        grade2 = "D";
    else
        grade2 = "F";
    int stuAverage2;
    stuAverage2 = average2;
