java.io.IOException：許可は拒否されましたが、ファイルが作成されました

Question

私はLinux環境で新しいファイルを作成するためにjava.io.File.createNewFile（）を使用しています。親フォルダのアクセス許可が777に設定されています。

次のアクセス許可は拒否されましたが、とにかくファイルが作成されています。

私はそれが許可例外をスローし、同時にファイルを作成する方法を確認していないので、任意の提案は理解されるであろう。

try { 
... 
File file = new File(PARENT_DIR, CHILD_DIR); 
file.createNewFile(); 
.. 
} catch (IOException e) { 
.. 
}
