Method

byte[]readAll(InputStream s)
read All 
byte[] temp = new byte[1024];
ByteArrayOutputStream os = new ByteArrayOutputStream();
try {
    while (true) {
        int read = s.read(temp, 0, temp.length);
        if (read <= 0)
            break;

...
byte[]readAll(InputStream stream)
Reads all the available bytes in the provided stream to a byte array. 
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
byte[] buffer = new byte[100];
int len = 0;
while ((len = stream.read(buffer)) != -1)
    outStream.write(buffer, 0, len);
return outStream.toByteArray();
StringreadAllAndClose(InputStream is)
read All And Close 
ByteArrayOutputStream out = new ByteArrayOutputStream();
try {
    int read;
    while ((read = is.read()) != -1) {
        out.write(read);
} finally {
    try {
...
byte[]readAllAndKeepOpen(InputStream bytes, int bufferSize)
Read all of the bytes in an input stream. 
try (ByteArrayOutputStream builder = new ByteArrayOutputStream()) {
    byte[] buffer = new byte[bufferSize];

    while ((read = bytes.read(buffer)) != -1) {
        builder.write(buffer, 0, read);
    return builder.toByteArray();
byte[]readAllBinary(InputStream stream)
fully reads a stream 
ByteArrayOutputStream o = new ByteArrayOutputStream();

while (true) {
    int bytesRead = stream.read(buffer);
    if (bytesRead == -1)
        break;
    o.write(buffer, 0, bytesRead);
return o.toByteArray();
byte[]readAllFrom(InputStream in, boolean chunked)
read All From 
if (in == null)
    throw new RuntimeException("Stream can't be null");
ByteArrayOutputStream bos = new ByteArrayOutputStream();

while ((read = fis.read(buf)) != -1) {
    bos.write(buf, 0, read);
fis.close();
...
byte[]readAllFromFile(String file)
read All From File 
FileInputStream fis = null;
try {
    fis = new FileInputStream(file);
    return readAllFrom(fis, false);
} catch (Exception e) {
    throw new RuntimeException("Unable to read file:" + file, e);
} finally {
    if (fis != null) {
