誰能告訴我如何編譯這個遊戲用記事本++？

我試圖編譯這樣的：

步驟1：F6

步驟2：

cd C:\Users\Noureddine\Desktop\Sokoban finale Version 
java Sokoban 
javac Sokoban.java 

，得到了以下錯誤：

Process started >>> Fehler: Hauptklasse Sokoban konnte nicht gefunden oder geladen werden <<< Process finished. (Exit code 1) javac Sokoban.java

備註：我嘗試安裝ViSimulator但安裝失敗。

預先感謝您的答案和提示！

Answer 1

對於編譯文件使用：

javac Sokoban.java 

由於您使用的包，我認爲你必須給全名來運行程序：

java sokoban.Sokoban
