package work;

import java.sql.*;

public class Means {
    public Means() {
    }


    public boolean login(String username, String password) {
        Connection con = null;
        PreparedStatement st = null;
        ResultSet rs = null;
        Conn c = new Conn();
        try {
            con = c.getcon();
            st = con.prepareStatement(
                    "select * from userInfo where name=? and password=?");
            st.setString(1, username);
            st.setString(2, password);
            rs = st.executeQuery();
            if (rs.next()) {
                return true;
            } else {
