ABOUT CLASS DECLARATION

Hi teacher, in the following class declaration,

public class StudentRegister{
private String name;
private String surname;
private int age;

public CustomerDetails(String firstname, String lastname, int new_age){
name = firstname;
surname = lastname;
age = new_age;

}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getSurname() {
return surname;
}

public void setSurname(String surname) {
this.surname = surname;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

}

there are private fields, constructor, and getter and setters as well. My question is that, if there are getters and setters in a class, do we really need constructors? I think no.
Thanks

constructor gurantee initializaion of fields when creating an object of the class, while you may forget to use setter methods to initialize fields.

Hi

Constructor is not a mandatory in case of getter and setter, constructor is using for initialize the object.
