Method

voidcopyStream(final InputStream in, final File dest)
Copies the content of the InputStream in to the File dest. 
FileOutputStream out = new FileOutputStream(dest);
BufferedInputStream bin = new BufferedInputStream(in);
try {
    byte[] buffer = new byte[BUFFER_SIZE];
    int len;
    while ((len = bin.read(buffer, 0, 2048)) != -1) {
        out.write(buffer, 0, len);
    out.close();
    bin.close();
} catch (IOException ex) {
    out.close();
    bin.close();
    throw ex;
longcopyStream(final InputStream is, final File destinationFile)
Downloads to a temporary location and renames on finish so no partials 
final File tmpFile = File.createTempFile("flickr_download", null);
try (final BufferedInputStream bis = new BufferedInputStream(is, BUF_SIZE);
        final BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(tmpFile),
                BUF_SIZE);) {
    final long total = ByteStreams.copy(bis, bos);
    tmpFile.renameTo(destinationFile);
    return total;
voidcopyStream(InputStream copyFrom, File copyTo)
Copy an input stream to a file location 
OutputStream to = new FileOutputStream(copyTo);
copyStream(copyFrom, to);
voidcopyStream(InputStream in, File dest)
copy Stream 
FileOutputStream out = new FileOutputStream(dest);
BufferedInputStream bin = new BufferedInputStream(in);
byte[] buffer = new byte[2048];
int len;
while ((len = bin.read(buffer, 0, 2048)) != -1) {
    out.write(buffer, 0, len);
out.close();
...
booleancopyStream(InputStream in, File dest)
Copy a file content to another location. 
try {
    OutputStream out = new FileOutputStream(dest);
    byte[] buf = new byte[1024];
    int len;
    while ((len = in.read(buf)) > 0) {
        out.write(buf, 0, len);
    in.close();
...
voidcopyStreamIntoFile(File outFile, InputStream is)
copy Stream Into File 
OutputStream os = new FileOutputStream(outFile);
byte[] buf = new byte[1024];
int len;
while ((len = is.read(buf)) > 0) {
    os.write(buf, 0, len);
is.close();
os.close();
...
voidcopyStreamsToFile(String path, Map streamMap)
copy Streams To File 
for (String copyBookName : streamMap.keySet()) {
    File copyBookFile = new File(path + copyBookName);
    OutputStream copyBookStream = new FileOutputStream(copyBookFile);
    OutputStreamWriter copyBookStreamWriter = new OutputStreamWriter(copyBookStream);
    copyBookFile.deleteOnExit();
    BufferedReader input = new BufferedReader(new InputStreamReader(streamMap.get(copyBookName)));
    String line;
    while ((line = input.readLine()) != null) {
...
voidcopyStreamsToFolder(Iterator> streams, File folder)
copy Streams To Folder 
while (streams.hasNext()) {
    Map.Entry<String, InputStream> entry = streams.next();
    File file = new File(folder, entry.getKey());
    copyStreamToFile(entry.getValue(), file);
voidcopyStreamToFile(final File to, final InputStream from)
Copy the contents of a stream to the given file. 
if (!to.exists()) {
    to.createNewFile();
BufferedOutputStream writer = new BufferedOutputStream(new FileOutputStream(to));
copyStream(writer, from);
writer.close();
voidcopyStreamToFile(InputStream from, File to)
copy Stream To File 
to.getParentFile().mkdirs();
OutputStream out = new BufferedOutputStream(new FileOutputStream(to));
try {
    copyStream(from, out);
} finally {
    out.close();
