Method

byte[]readBytes(InputStream inputStream)
read Bytes 
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
    byteBuffer.write(buffer, 0, len);
return byteBuffer.toByteArray();
...
byte[]readBytes(InputStream inputStream)
read Bytes 
assert inputStream != null;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try {
    int b;
    while ((b = inputStream.read()) != -1) {
        bos.write(b);
} finally {
...
byte[]readBytes(InputStream inputStream)
read Bytes 
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
    byteBuffer.write(buffer, 0, len);
return byteBuffer.toByteArray();
...
byte[]readBytes(InputStream inputStream)
read Bytes 
ByteArrayOutputStream byteOut = new ByteArrayOutputStream();
copyStream(inputStream, byteOut);
return byteOut.toByteArray();
byte[]readBytes(InputStream inputStream)
Reads all bytes from given InputStream. 
ByteArrayOutputStream arrayOutputStream = new ByteArrayOutputStream();
byte[] buff = new byte[1024];
int r = 0;
while ((r = inputStream.read(buff)) >= 0) {
    arrayOutputStream.write(buff, 0, r);
return arrayOutputStream.toByteArray();
byte[]readBytes(InputStream inputStream)
read Bytes 
BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);
ByteArrayOutputStream output = new ByteArrayOutputStream();
byte[] array = new byte[1024];
while (true) {
    int len = bufferedInputStream.read(array);
    if (len == -1) {
        break;
    output.write(array, 0, len);
return output.toByteArray();
byte[]readBytes(InputStream inputStream)
Reads all data from an InputStream 
ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
byte[] buffer = new byte[32 * 1024];
int bytesRead;
do {
    bytesRead = inputStream.read(buffer, 0, buffer.length);
    if (bytesRead > 0)
        byteStream.write(buffer, 0, bytesRead);
} while (bytesRead > 0);
...
byte[]readBytes(InputStream inputStream)
This method consumes an inputstream, returning its content then closing it. 
try {
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(inputStream.available());
    copy(inputStream, byteArrayOutputStream);
    return byteArrayOutputStream.toByteArray();
} finally {
    inputStream.close();
byte[]readBytes(InputStream inputStream, boolean close)
read Bytes 
ByteArrayOutputStream bufStream = new ByteArrayOutputStream();
final int size = 512;
byte[] buf = new byte[size];
int readSize;
try {
    while ((readSize = inputStream.read(buf, 0, size)) > -1) {
        bufStream.write(buf, 0, readSize);
    if (close) {
        inputStream.close();
} catch (IOException e) {
    e.printStackTrace();
    System.exit(1);
return bufStream.toByteArray();
voidreadBytes(InputStream inputStream, byte[] buffer, int offset, int length)
Reads a sequence of bytes from the input, raising an EOFException if end of stream is reached. 
if (inputStream.read(buffer, offset, length) < length) {
    throw new EOFException();
