Cannot insert data into mysql database using Java (jframe)

Question

I've tried connecting my jframe to mysql database to insert records into the database using jframe but have not been successful yet. I'm having a hard time finding the error(s). The program shows no error while running but does not add values to database. Below the database name is 'tanishq' and t1, t2, t3, t4 and t5 are name of the textfields.

Here is my code:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    try {
        Class.forName("java.sql.driver");
        Connection con =
                DriverManager.getConnection
                        (" jdbc:mysql://localhost:3306/tanishq" + "user=root& password=...");
        Statement stmt = (Statement) con.createStatement();
        String query = "insert into jewel values
        ('"+t1.getText()+"',
                '"+ t2.getText()+"',
                "+ t3.getText()+",
                "+ t4.getText()+",
                "+ t5.getText()+")";
        System.out.println(query);
        stmt.executeUpdate(query);
        j1.showMessageDialog(null, "RECORD ADDED");
    } catch
            (Exception e) {
        j1.showMessageDialog(null, e.getMessage());
    }
}
