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

public class Main {
  public static void main(String args[]) throws Exception {
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    Connection conn = DriverManager
        .getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};"
            + "Dbq=C:\\Users\\Public\\uls\\ulsTest.mdb;"
            + "SystemDB=C:\\Users\\Public\\uls\\Security.mdw;" + "Uid=Gord;"
            + "Pwd=obfuscated;" + "ExtendedAnsiSQL=1;");
    Statement s = conn.createStatement();
    s.execute("CREATE USER Tim pwd");
    System.out.println("User 'Tim' created.");
    s.execute("DROP USER Tim");
    System.out.println("User 'Tim' dropped.");
    s.close();
    conn.close();
  }
}
