I have code of Connection class, where it gets a connection only from one database. Look at the DBConnection.java below

```
package eksim.db.sql;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DBConnection {

    public Connection conn=null;
    private static DBConnection dbConn=null;
    static final String DB_URL=
            "jdbc:sqlserver://10.0.0.47\\test;databaseName=a;";
    static final String DB_USER="sa";
    static final String DB_PASS="123";

    public DBConnection(){
         if(conn==null){
             try{
                 Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
                 conn=DriverManager.getConnection(DB_URL, DB_USER, DB_PASS);
             }
             catch(Exception ex){
                 ex.printStackTrace();
             }
         }
    }

    public static  DBConnection getInstance(){
        DBConnection conn=null;
        if(dbConn==null){
            System.out.println("New");
            dbConn=new DBConnection();
            conn=dbConn;
        } else{
            conn=dbConn;
        }
        return conn;
    }
    public Connection getCon() throws SQLException{
        return this.conn;
    }
}

```

Now, i want to create another connection into the different database. Could anyone give me suggestion to modify this code in order to get the result of Connection into 2 database? thanks for any reply
