我有一个问题,在写入文件时,在关闭之前,我们应该包括flush()?? 如果是这样它会做什么呢？不流自动冲洗？编辑:

那么冲洗它实际上做了什么？

我有一个方法,使用此代码通过TCP套接字接收文件:

FileOutputStream fileStream = new FileOutputStream(filename.getName());
while (totalRead < size) {
    if (size - totalRead > CHUNKSIZE) {
        read = getInputStream().read(buffer, 0, CHUNKSIZE);
    } else {
        read = getInputStream().read(buffer, 0, size - totalRead);
    }
    totalRead += read;
    fileStream.write(buffer, 0, read);
    fileStream.flush();

    if (System.currentTimeMillis() > nextPrint) {
        nextPrint += 1000;
        int speed = (int) (totalRead / (System.currentTimeMillis() - startTime));
        double procent = ((double)totalRead / size) * 100;
        gui.setStatus("Reciving: " + filename + " at " + speed + " kb/s, " …
