硒教程麻煩，我如何解決我收到的許多錯誤？

Question

我目前正在參加Selenium教程Here，我完全按照每一步操作，但是我的Eclipse程序一直在拋出錯誤。我正在使用Selenium 3，而本教程適用於舊版本。除此之外，我找不到任何全面的教程。如何修復以下代碼中的錯誤？我已經評論了每行後的確切錯誤。代碼已經包含了一些評論，所以在一行的開頭忽略任何評論。其他一切都應該是錯誤消息。

我還需要知道如何使用Eclipse來設置我的類路徑，以允許它訪問GeckoDriver，這可能會或可能不會解決問題。

我想我所做的只是移動類以外的進口和刪除一個}和錯誤走了。我修復了縮進並刪除了所有與錯誤相關的評論。試試這個......
