Java & JDBC

First, download the latest version of the Postgres JDBC driver, and put that jar file in your project's classpath (or, add this dependency to Maven)

All you need to know to use Java with bit.io is your connect string - you can find this by clicking on the green "connect" button on your repo. You can paste that string right into your code as the connection url, or you can copy from the example below on how to configure the connect string with variables.

🚧
Replace / with . in Database Name
To work with JDBC, you must modify the database name from the "Connect" menu by replacing the / between the username and database name components with a .. So "dliden.2020_Census_Reapportionment" will work, but "dliden/2020_Census_Reapportionment" will not.

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

import java.sql.ResultSetMetaData;
import java.sql.Statement;
import java.util.Properties;

public class BitioExample {
   public static void main(String args[]) {
      Connection c = null;
      String bitApiKey = "<your_bitdotio_password>";
      String bitDB = "dliden.2020_Census_Reapportionment";
      String bitUser = "<your_bitdotio_username>";
      String bitHost = "db.bit.io";
      String bitPort = "5432"; // We keep this as a string here as we are concact'ing it into the connection string
      Properties props = new Properties();
      props.setProperty("sslmode","verify-full"); // if verify-full fails, use 'require'
      props.setProperty("user",bitUser);
      props.setProperty("password",bitApiKey);
      try {
         Class.forName("org.postgresql.Driver");
         c = DriverManager
            .getConnection("jdbc:postgresql://" + bitHost + ":" + bitPort + "/" + bitDB, props);
         Statement stmt = c.createStatement();
         ResultSet rs = stmt.executeQuery("SELECT * FROM \"dliden/2020_Census_Reapportionment\".\"Historical Apportionment\" limit 10;" );
         while (rs.next()) {
             ResultSetMetaData rsmd = rs.getMetaData();
             // The ResultSet .getXXX() methods expect the column index to start at 1. 
             // No idea why.
             for (int i = 1; i <= rsmd.getColumnCount(); i++) {
               System.out.print(rsmd.getColumnName(i) + "="+ rs.getString(i) + " ");
             }
             System.out.println();
         }

      } catch (Exception e) {
         e.printStackTrace();
         System.err.println(e.getClass().getName()+": "+e.getMessage());
         System.exit(0);
      }
   }
}

The code above is available on github, along with instructions for compiling and executing the code.
