Question

My problem is when I get the data from a text file it seems to be in the wrong encoding or somthing. I dont know how to get around this issue sorry. Thanks in advance. Here is the code.

private static String readLogFile(String path, File f) throws IOException {
    if (f.exists()){
    String data;
        try (RandomAccessFile raf = new RandomAccessFile(f, "rw")) {
            char ch = raf.readChar();
            raf.seek(f.length());
            String dataCh = String.valueOf(ch);
            data = dataCh.toString();
            System.out.println(data);
        }
        return data;
    }

    else{
        String data = "";
        return data;
    }
}

From the Java Docs

This method blocks until the two bytes are read, the end of the stream
is detected, or an exception is thrown.

Note, “two bytes are read”

Because Java supports Unicode character’s the stream is automatically assuming that reading a character from the stream needs to produce a Unicode character.

Try char ch = (char)raf.readByte(); instead
