Thread: Help with code outputting wrong info

This is the setter and getter part of the program;

public class Student
{
 
    private String name, address, major;
    private double gpa;
 
 
    public Student(String name, String address, String major)
	 {
        this.name = name;
		  this.address = address;
		  this.major = major;
		  gpa();
    }
 
	 //Will return name
    public String getName()
    {
        return name;
    }
 
	 //Will return address
    public String getAddress()
    {
        return address;
    }
 
	 //Will return major
    public String getMajor()
    {
        return major;
    }
 
    //Will calculate and return GPA
    public double gpa()
	 {
    Random generator = new Random();
 
    float gpa = (float) (generator.nextDouble() * 4.0 + 0.5);
 
    return gpa;
    }
 
}

This is the tester

public class StudentTester
{
	public static void main(String[] args)
	{
		Student student1 = new Student("Kevin","100 Main Street","Spanish");
		System.out.println(student1.toString());
		System.out.println(gpa()); //error here
 
		Student student2 = new Student("Jim","15 Key Road","Art");
		System.out.println(student2.toString());
 
		Student student3 = new Student("Frank","8302 School Drive","Math");
		System.out.println(student3.toString());
	}
}

Now I'm having two issues, when I run the program without the GPA in the tester part it just outputs with random letters and numbers like so;

Student@9304b1
Student@190d11
Student@a90653

Also, I cannot figure out why I cannot output a random GPA.
