Objects & Classes - Beginner question

Ive just started a programming course but i have entered a semester behind so im rushing to catch up. My question is why is this not printing the correct name, phone and id????

Class file

Code:

---

public class Student {
                private String name;
                private String phone;
                private String studNo;
               
                public Student(String name, String phone, String studNo){
                        this.name = name;
                        this.phone = phone;
                        this.studNo = studNo;
                }
        public String getName(){
                return this.name;
               
        }
        public String getPhone(){
                return this.phone;
               
        }
        public String getStudNo(){
                return this.studNo;
               
        }
       
       
}

Test file

Code:

---

public class StudentTest {
        public static void main(String[] args){
                Student s1, s2;
               
                s1 = new Student("Jony", "042", "123");
                s2 = new Student("Michael", "123465", "98765");
               
                System.out.println(s1);
                System.out.println(s2);
               
               
        }
}

---

The out put is -Student@3ae48e1b
Student@732dacd1


also if i change the phone and studNo to int it gives me this error msg - "The constructor Student(String, String, String) is undefined"

s1, s2 are objects, and you just print them.

Think like this, object is just a blue-print of your class with all the information you have. So you have meaning of it with the individual properties.

To retrieve the information you've to call the public accessors. For example, if you want to display the name of the student s1,

Code:

---

System.out.println(s1.getName);

---

Do you about what the dot operator does?

Ahhhh. Thakyou..

I altered it so it read:

System.out.println("Name: " + s1.name + " Phone: " + s1.phone + " Student number: " + s1.studNo);
System.out.println("Name: " + s2.name + " Phone: " + s2.phone + " Student number: " + s2.studNo);

Thanks Eranga.

You are welcome. :)
