回答1:

You have invisible character in these lines, \8232 is line separator. Possibly you copied it somewhere.

Try to paste it in Notepad/TextEdit and copy text from there. Point is to get rid of formatting and extra characters. Or you can just delete these lines and retype them manually.

private InputStream checkForUtf8BOMAndDiscardIfAny(InputStream inputStream) throws IOException {
 PushbackInputStream pushbackInputStream = new PushbackInputStream(new 
 BufferedInputStream(inputStream), 3);
 byte[] bom = new byte[3];
 if (pushbackInputStream.read(bom) != -1) {
    if (!(bom[0] == (byte) 0xEF && bom[1] == (byte) 0xBB && bom[2] == (byte) 0xBF)) {
        pushbackInputStream.unread(bom);
    }
 }
 return pushbackInputStream; 
}
