import java.sql.SQLException;
import java.sql.SQLNonTransientConnectionException;
import java.sql.Statement;

/**

in a database.
*/

public class Cloud_sql {
public static void main(String[] args) throws SQLNonTransientConnectionException 
,IOException, SQLException {

String instanceConnectionName = ;
String databaseName = ;


String IP_of_instance = ;
String username = ;
String password = ;

String jdbcUrl = String.format(
    "jdbc:mysql://%s/%s?cloudSqlInstance=%s"
        + "&socketFactory=com.google.cloud.sql.mysql.SocketFactory&useSSL=false",
IP_of_instance,
    databaseName,
    instanceConnectionName);

Connection connection = DriverManager.getConnection(jdbcUrl, username, password);

try (Statement statement = connection.createStatement()) {
  ResultSet resultSet = statement.executeQuery("SHOW TABLES");
  while (resultSet.next()) {
    System.out.println(resultSet.getString(1));
  }
}catch(Exception e){
  e.printStackTrace();
}
}
}
