    public static void main(String args[]) throws Exception {

        sc = new Scanner(System.in);
        System.out.println("hii");
        Class.forName("com.mysql.jdbc.Driver");
        Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/rsystems", "root", "rsystems");
        PreparedStatement stmt = con.prepareStatement("insert into user valiues(?,?)");
        System.out.println("Enter id:");
        int no = sc.nextInt();
        System.out.println("Enter name:");
        String name = sc.next();
        stmt.setInt(1, no);
        stmt.setString(2, name);
        //I think I need to commit over here and I have tried the same but even with that I didn't see my inserted data in database
    }
