Flushes this output stream and forces any buffered output bytes to be written out.

Usage

From source file:Main.java

public static void copyFile(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[8192];
    int read;//from  w w  w. j av a2s.co  m
    while ((read = in.read(buffer)) != -1) {
        out.write(buffer, 0, read);
    }
    out.flush();
}
