Solving task 1 by 1 from bundle of task data

import java.sql.*;

class  Retrieve{
public static void main(String[] args){
    try{
           Class.forName("com.mysql.jdbc.Driver");
           Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
           Statement st=con.createStatement();
           ResultSet rs=st.executeQuery("select * from employee");

           ArrayList name=new ArrayList();
           ArrayList address=new ArrayList();
           ArrayList contact=new ArrayList();
           ArrayList email=new ArrayList();

           while(rs.next()){
             name.add(rs.getString("name"));
              address.add(rs.getString("address"));
              contact.add(rs.getInt("contactNo"));
              email.add(rs.getString("email"));
              }
           for(int i=0;i<name.size();i++){
           System.out.println(name.get(i)+"\t"+address.get(i)+"\t"+contact.get(i)+"\t"+email.get(i));
           }
    }
    catch(Exception e){
    System.out.println(e);
    }

    }
}

using arraylist makes me more problem because i need to pass the value to the constructor.ive tried to change to single array,but got error.cannot find symbol constructor...

for(int i=0;i<count;i++)
                    {
                        String user_input = input[i];
                        int t_number = t_num[i];
                        String user_id = id[i];
                        int taskid = task_id[i];

                        Tway gen = new Tway(user_input , t_number , user_id , taskid);
                        gen.solve();

                     }

whats ive done wrong?
