Encountering "error: incompatible types: unexpected return value" and "error: 'void' type not allowed here"

I'm still very new to Java and I've been stuck on this lab question for my Java course for a while, and I thought everything was good once I got to this point with my code:

public class Student {
   // TODO: Build Student class with private fields and methods listed above
   // private variables
   private String name;
   private double gpa;

   // TODO: Define two private member fields
   // default constructor
   public Student() {
      name = "Louie";
      gpa = 1.0;
   }
   
   public Student(String name, double gpa) {
      this.name = name;
      this.gpa = gpa;
   }
    
    public void getName() {
      // TODO: Assign parameter to instance field
      return name;
   }
    
   public void setName(String name) {
      // TODO: Assign parameter to instance field
      this.name = name;
   }
   
   public double getGPA() {
      // TODO: Assign parameter to instance field
      return gpa;
   }
   
   public void setGPA(double gpa) {
      // TODO: Assign parameter to instance field
      this.gpa = gpa;
   }
   
   // TODO: Add three more methods
   
   
   public static void main(String[] args) {
      Student student = new Student();
      System.out.println(student.getName() + "/" + student.getGPA());
      
      student.setName("Felix");
      student.setGPA(3.7);
      System.out.println(student.getName() + "/" + student.getGPA());
   }
}

But then I got these errors:

Student.java:21: error: incompatible types: unexpected return value
return name;
^
Student.java:44: error: 'void' type not allowed here
System.out.println(student.getName() + "/" + student.getGPA());
^
Student.java:48: error: 'void' type not allowed here
System.out.println(student.getName() + "/" + student.getGPA());

I tried googling the errors to see how others solved these, but I would get rid of one error and encounter a completely different one. I am unsure how to go about solving the "unexpected return value" error. But as for the "void type not allowed here" I tried removing 'void' from the 'public static void main' as I saw that recommended to others encountering the same issue but this caused other errors.

The expected outcome for the code should be something like:
Louie/1.0
Felix/3.7

I am confused as to why the main class is having problems as this part of the code was already filled in when I started the lab.

On line 21 you are returning name of type String but your getName() function's signature is public void getName(). To fix this change void to String: public String getName().
