Usage

From source file:Main.java

public static void WriteFile(InputStream stream, String fileName) throws IOException {
    FileOutputStream fos = new FileOutputStream(fileName);
    byte[] buff = new byte[1024];
    int readLen;/*from  www.ja  v  a  2s  . c om*/
    do {
        readLen = stream.read(buff);
        if (readLen > 0)
            fos.write(buff, 0, readLen);
    } while (readLen > 0);

    fos.close();
}
