底下是一個針對UTF-8編碼的BOMKiller程式~ 如果你開發程式時所採用的文字編輯器會自動為你加上BOM的話~ 那BOMKiller可以協助你更容易刪除這些BOM~
好久沒寫Java了~~ 趁這個機會再回味一下用UltraEdit純手工寫程式~

FileChannel fic = fis.getChannel();
FileChannel foc = new FileOutputStream(toFile).getChannel();
fic.transferTo(3, fic.size(),foc);
fic.close();
foc.close();
f.delete();
toFile.renameTo(new File(path));
}
}
}
}catch(Exception e)
{
e.printStackTrace();
}
}
}
用法
Usage:java BOMKiller [directory_path] [suffix_name]
e.g.
java BOMKiller C:\htdocs .php
