Java – convert resultset to string array

I need to convert my result set to a string array I'm reading email addresses from the database, and I need to be able to send them, such as:

message.addRecipient(Message.RecipientType.CC,"abc@abc.com,abc@def.com,ghi@abc.com");

This is the code I read the email address:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class Test {

    public static void main(String[] args) {
        Connection conn = null;
        String iphost = "localhost";
        String dbsid = "ASKDB";
        String username = "ASKUL";
        String password = "askul";

        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
            String sql = "SELECT * FROM EMAIL";
            conn = DriverManager.getConnection("jdbc:oracle:thin:@" + iphost + ":1521:" + dbsid,username,password);
            Statement st = conn.createStatement();
            ResultSet rs = st.executeQuery(sql);
            String[] arr = null;
            while (rs.next()) {
                String em = rs.getString("EM_ID");
               arr = em.split("\n");
               for (int i =0; i < arr.length; i++){
                   System.out.println(arr[i]);
               }
            }
        } catch (Exception asd) {
            System.out.println(asd);
        }
    }
}

My output is:

myemailaddress@abc.com
myotheremail@abc.com

I need this:

myemailaddress@abc.com,myotheremail@abc.com

I am using Oracle 11g

Solution

Get the desired output:

Replace these lines

String[] arr = null;
while (rs.next()) {
    String em = rs.getString("EM_ID");
    arr = em.split("\n");
    for (int i =0; i < arr.length; i++){
        System.out.println(arr[i]);
    }
}

adopt

String arr = null;
while (rs.next()) {
    String em = rs.getString("EM_ID");
    arr = em.replace("\n",",");
    System.out.println(arr);
}
