Making an update in database

Question

Suppose I have these 3 classes:
class Student {
  private int m_intID;
  private String m_strName;
   public Student(int id, String n) {
// getters and setters
// toString ...
class DBStudent {
  // data members
  // methodes and functions
  public void updateStudent(int id, String name)  {
   try {
      // connection and update query ...
    } catch (SQLException sqle) {
      sqle.getMessage();
  public void updateStudent(Student studentSomeOne) {
    // update using studentSomeOne.getXXXXX ..
class Main {
  public static void main (String[] args) {
    Student studentJava = new Student ();
    DBStudent dbstudentJava = new DBStudent();
    // what is the best solution right here ??
   dbstudentJava.updateStudent(1784,"Roberto Carlos");
   // OR
   studentJava.setID (1784);
   studentJava.setNamen ("Roberto Carlos");
   dbstudentJava.updateStudent(studentJava);
}pleas read the comments :-) and tell me which one is the best solution and why ?

Answer 1

If you're asking, "how do I store an object's state in a database?", then the answers are:
1) do it by hand using JDBC
2) use an object-relational mapping tool, like Hibernate.
