Description

 

public void clearOutputTable() throws Exception {
   Class.forName(DRIVER_CLASS);
   try (
      Connection conn = DriverManager.getConnection(DB_URL);
      Statement stat = conn.createStatement()) {
      stat.execute("DELETE FROM " + OUTPUT_TABLE);

      stat.close();
      conn.close();
   }
}

Unnecessary close of stat and conn can be removed.
