Method

voidcopyStream(@Nonnull InputStream in, @Nonnull OutputStream out)
copy Stream 
byte[] buf = new byte[8192];
int len;
while ((len = in.read(buf)) >= 0)
    out.write(buf, 0, len);
voidcopyStream(ByteArrayOutputStream source, ByteArrayOutputStream target)
Copies source stream to target. 
ByteArrayOutputStream memContentStream = source;
if (memContentStream != null) {
    memContentStream.writeTo(target);
    memContentStream.flush();
} else {
    int c;
    ByteArrayInputStream inStream = new ByteArrayInputStream(source.toByteArray());
    while ((c = inStream.read()) != -1) {
...
voidcopyStream(final InputStream in, final OutputStream out)
Copies the contents of a stream to another. 
int bytesRead;
byte[] b = new byte[10000];
while ((bytesRead = in.read(b)) != -1) {
    out.write(b, 0, bytesRead);
out.flush();
voidcopyStream(final InputStream in, final OutputStream out)
Copy stream. 
final byte[] bytes = new byte[8192];
int cnt;
while ((cnt = in.read(bytes)) != -1) {
    out.write(bytes, 0, cnt);
voidcopyStream(final InputStream in, final OutputStream out, final int bufferSize)
Copies the contents of an java.io.InputStream to an java.io.OutputStream , using buffer size provided. 
final byte[] buffer = new byte[bufferSize];
int byteRead = 0;
while ((byteRead = in.read(buffer)) >= 0) {
    out.write(buffer, 0, byteRead);
intcopyStream(final InputStream in, final OutputStream out, int iMax)
copy Stream 
if (iMax < 0)
    iMax = Integer.MAX_VALUE;
final byte[] buf = new byte[8192];
int byteRead = 0;
int byteTotal = 0;
while ((byteRead = in.read(buf, 0, Math.min(buf.length, iMax - byteTotal))) > 0) {
    out.write(buf, 0, byteRead);
    byteTotal += byteRead;
...
voidcopyStream(final InputStream input, final OutputStream output, long count)
Copies count bytes from input to output. 
final byte[] buffer = new byte[64 * 1024];
if (count < 0) {
    int read;
    while ((read = input.read(buffer)) != -1) {
        output.write(buffer, 0, read);
} else {
    while (count > 0) {
...
longcopyStream(final InputStream inputStream, final OutputStream out)
copy Stream 
return copyStream(inputStream, out, 10240);
voidcopyStream(final InputStream inputStream, final OutputStream outputStream)
copy Stream 
final byte[] buffer = new byte[1024 * 4];
int c;
while (-1 != (c = inputStream.read(buffer))) {
    outputStream.write(buffer, 0, c);
intcopyStream(final InputStream inputStream, final OutputStream outputStream)
copy Stream 
if (inputStream == null) {
    return 0;
int result = 0;
final byte[] buf = new byte[DEFAULT_BUFFER_SIZE];
for (;;) {
    final int numRead = inputStream.read(buf);
    if (numRead == -1) {
