Input data from Java to SQL Database

Question

I have a school project where I have to create a register and login GUI with Netbeans and then link it with a SQL database. I create the database and my login work, but I am struggling with my register maybe someone can help me. This is what I did so far. Sorry for the long code post ,but my mistake could be anywhere here.

public class Register extends javax.swing.JFrame {

Connection conn = null;
Statement stat = null;
ResultSet res = null;

public Register() 
{
    initComponents();
}

private Connection connect() {
    // SQLite connection string
    String url = "\"jdbc:derby://localhost:1527/MyDataBase\", \"LouwDataBase\", \"1234\"";
    Connection conn = null;
    try {
        conn = DriverManager.getConnection(url);
    } catch (SQLException e) {
        System.out.println(e.getMessage());
    }
    return conn;
}

public void insert(String Email, String Password, String Name, String Surname, String Address, String Cell)
{
    String sql = "INSERT INTO Table1Test(Email, Password, Name, Surname, Address, Cell) VALUES(?,?,?,?,?,?)";

    try (Connection conn = this.connect();
        PreparedStatement pstmt = conn.prepareStatement(sql)) {
        pstmt.setString(1, Email);
        pstmt.setString(2, Password);
        pstmt.setString(3, Name);
        pstmt.setString(4, Surname);
        pstmt.setString(5, Address);
        pstmt.setString(6, Cell);
        pstmt.executeUpdate();
    } 
    catch (SQLException e) 
    {
        System.out.println(e.getMessage());
    }
}

I think your problem is in your URL you should not set your url like a String like you do :

String url = "\"jdbc:derby://localhost:1527/MyDataBase\", \"LouwDataBase\", \"1234\"";

You have to separate the url, the username and password like this :

private Connection connect() {
    // SQLite connection string
    String url = "jdbc:derby://localhost:1527/MyDataBase";
    String username = "LouwDataBase"; 
    String password = "1234"; 
    Connection conn = null;
    try {
        conn = DriverManager.getConnection(url, username, password);
    } catch (SQLException e) {
        System.out.println(e.getMessage());
    }
    return conn;

}
