Accessor returns string as null

[corong1997]

So I can't figure out why the accessor (I'm guessing it's because of the accessor) keeps returning the String name as null when I run the program. I am trying to use a scanner in the tester program to store a string for the name, but whenever I try to print it out, the virtual machine prints "null" instead of the name.

Tester-

import java.util.Scanner;

public class StudentTester
{
    
    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        
        System.out.println("What is student 1's name?");
        String name1 = scan.nextLine();
        
        System.out.println("What is student 2's name?");
        String name2 = scan.nextLine();
        
        Student s1 = new Student();
        Student s2 = new Student(8,89,712,name2);
        System.out.println(s1.getName() + "'s current Average is: " + s1.getAverage()
                            + " Total is: " + s1.getTotal() + " Number of Quizzes is: "
                            + s1.getQuizNumber());
        
        System.out.println(s2.getName() + "'s current Average is: " + s2.getAverage()
                            + " Total is: " + s2.getTotal() + " Number of Quizzes is: "
                            + s2.getQuizNumber());
                            
        System.out.println("==========After new quiz is entered ============");        
        s1.addQuiz(20);
        s2.addQuiz(50);
        
        System.out.println(s1);
        System.out.println(s2);
        
    }
    
}

Class-

public class Student
{

//Instance Variables

private int totalScore;
private int averageScore;
private int quizNumber;
private String name;
//Construcctors
public Student()
{
    totalScore = 0;
    quizNumber = 0;
    averageScore = 0;
    name = null;
}
public Student(int number, int average, int total, String name)
{
    quizNumber = number;
    totalScore = total;
    averageScore = average;
    name = name;
}

//Accessors
public double getAverage()
{
    return averageScore; 
}
public int getTotal()
{
    return totalScore;
}
public int getQuizNumber()
{
    return quizNumber;
}

public String getName()
{
    return name;
}
//Mutators
public void addQuiz(int quiz)
{
    totalScore = totalScore + quiz;
    quizNumber = quizNumber + 1;
    averageScore = totalScore / quizNumber;
}


//toString
public String toString()
{
    String str = "Student's average score is " + averageScore + " in " + quizNumber + " tests";
    return str;
}
}

Because name defaults to nulll. When you do name = name that doesn't change the instance field. You need to do this.name = name to distinguish between the instance field and the local argument.
