Method

StringreadAll(InputStream inputStream)
read All 
StringBuilder result = new StringBuilder();
BufferedInputStream buffered = new BufferedInputStream(inputStream);
int i;
while ((i = buffered.read()) != -1) {
    result.append((char) i);
return result.toString();
byte[]readAll(InputStream is)
read All 
int pos = 0;
byte[] buffer = new byte[1024];
while (true) {
    int toRead;
    if (pos >= buffer.length) {
        toRead = buffer.length * 2;
        if (buffer.length < pos + toRead) {
            buffer = Arrays.copyOf(buffer, pos + toRead);
...
intreadAll(InputStream is, byte[] buffer, int offset, int length)
read All 
int readLength = 0;
while (length > 0) {
    int sublen = is.read(buffer, offset, length);
    if (sublen <= 0) {
        return readLength;
    length -= sublen;
    offset += sublen;
...
StringreadAll(InputStream stream)
Reads the entire content of a stream to a string. 
Scanner scanner = new Scanner(stream).useDelimiter("\\A");
return scanner.hasNext() ? scanner.next() : null;
Object[]readAll(InputStream stream)
deserializes from the given stream and returns the object from it. 
ObjectInputStream ois;
Vector<Object> result;
if (!(stream instanceof BufferedInputStream)) {
    stream = new BufferedInputStream(stream);
ois = new ObjectInputStream(stream);
result = new Vector<Object>();
try {
...
intreadAllBuffer(InputStream stream, byte[] buffer)
read All Buffer 
return readAllBuffer(stream, buffer, 0, buffer.length);
byte[]readAllFrom(java.io.InputStream is)
Reads an input stream til EOF and returns all bytes read. 
byte[] buf = new byte[8192];
int i = 0;
int n = 0, r;
final int SIZE = 4096;
while (true) {
    while (buf.length <= n + SIZE + 1)
        buf = resizeVec(buf, 2 * buf.length);
    r = is.read(buf, n, SIZE);
...
byte[]readAllFromStream(InputStream is)
read All From Stream 
DataInputStream dis = new DataInputStream(is);
byte[] buffer = new byte[4096];
int totalBytesRead = 0, bytesRead;
while ((bytesRead = dis.read(buffer, totalBytesRead, buffer.length - totalBytesRead)) >= 0) {
    if (totalBytesRead + bytesRead >= buffer.length) {
        byte[] oldBuffer = buffer;
        buffer = new byte[oldBuffer.length * 2];
        System.arraycopy(oldBuffer, 0, buffer, 0, oldBuffer.length);
...
StringreadAllInString(InputStream in)
read All In String 
return new String(readAll(in));
