Splitting files into chunks with size bigger than 127

The problem is that PART_SIZE is a byte; its maximum value is therefore indeed 127.

The code you have at the moment however is full of problems; for one, incorrect resource handling etc.

Here is a version using java.nio.file:

private static final String FILENAME = "TextFile.txt";private static final int PART_SIZE = xxx; // HEREpublic static void main(final String... args)    throws IOException{    final Path file = Paths.get(FILENAME).toRealPath();    final String filenameBase = file.getFileName().toString();    final byte[] buf = new byte[PART_SIZE];        int partNumber = 0;    Path part;    int bytesRead;    byte[] toWrite;    try (        final InputStream in = Files.newInputStream(file);    ) {        while ((bytesRead = in.read(buf)) != -1) {            part = file.resolveSibling(filenameBase + ".part" + partNumber);            toWrite = bytesRead == PART_SIZE ? buf : Arrays.copyOf(buf, bytesRead);            Files.write(part, toWrite, StandardOpenOption.CREATE_NEW);            partNumber++;        }    }}

List<PDDocument> Pages=new ArrayList<PDDocument>();     Document.load(filePath);    try {        Splitter splitter = new Splitter();        splitter.setSplitAtPage(NoOfPagesDocumentWillContain);    Pages = splitter.split(document);    }catch(Exception e)    {        l        e.getCause().printStackTrace();    }
