Method

voidcopyStreamSafely(InputStream in, ByteArrayOutputStream os)
Copies the content from in into os. 
try {
    copyStreamUnsafelyUseWithCaution(in, os);
} finally {
    in.close();
FilecopyStreamToFile(final InputStream stream, final File output)
Helper function for writing a text stream to a file. 
final BufferedReader r = new BufferedReader(new InputStreamReader(stream));
String l = null;
final PrintWriter writer = new PrintWriter(new FileWriter(output));
while ((l = r.readLine()) != null) {
    writer.println(l);
writer.close();
r.close();
...
FilecopyStreamToFile(InputStream input, String outputPath)
copy Stream To File 
File file = new File(outputPath);
try {
    DataOutputStream out = new DataOutputStream(new BufferedOutputStream(new FileOutputStream(file)));
    InputStream is = input;
    byte[] buf = new byte[1024];
    int len;
    while ((len = is.read(buf)) > 0) {
        out.write(buf, 0, len);
...
voidCopyStreamToFile(InputStream inputStream, File outputFile)
Copies a InputStream into a file. 
InputStreamReader in = new InputStreamReader(inputStream);
FileWriter out = new FileWriter(outputFile);
int c;
while ((c = in.read()) != -1) {
    out.write(c);
in.close();
out.close();
...
FilecopyStreamToFile(InputStream inputStream, File outputFile)
copy Stream To File 
OutputStream outputStream = new FileOutputStream(outputFile);
byte[] buf = new byte[BUFFER_SIZE];
int len;
while ((len = inputStream.read(buf)) > 0) {
    outputStream.write(buf, 0, len);
outputStream.close();
inputStream.close();
...
voidcopyStreamToFile(InputStream is, File outputFile)
Copy contents of a stream to a target file. 
OutputStream os = new BufferedOutputStream(new FileOutputStream(outputFile));
copyStreamToStream(is, os);
os.close();
voidcopyStreamToFile(InputStream stream, String outputFilePath)
Uses the default charset 
BufferedInputStream is = new BufferedInputStream(stream);
OutputStream os = null;
try {
    os = new FileOutputStream(new File(outputFilePath));
    byte[] b = new byte[1024];
    int read;
    while ((read = is.read(b)) != -1) {
        os.write(b, 0, read);
...
FilecopyStreamToFileBinary(final InputStream stream, final File output)
Helper function for writing a binary stream to a file. 
final FileOutputStream out = new FileOutputStream(output);
final byte buf[] = new byte[1024];
int len = 0;
while ((len = stream.read(buf)) > 0)
    out.write(buf, 0, len);
out.close();
stream.close();
return output;
...
voidcopyStreamToStream(final InputStream input, final OutputStream output)
Copy any input stream to output stream. 
InputStream is = null;
OutputStream os = null;
int ch;
try {
    if (input instanceof BufferedInputStream) {
        is = input;
    } else {
        is = new BufferedInputStream(input);
...
voidcopyStreamToStream(InputStream in, OutputStream out)
Copy the contents of an InputStream, up to EOF, to the given OutputStream. 
byte[] buf = new byte[BUFFER_SIZE];
int len;
try {
    while ((len = in.read(buf)) > 0) {
        out.write(buf, 0, len);
} finally {
    in.close();
