Method

byte[]getBytes(InputStream inputStream)
get 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[]getFileByte(InputStream inputStream)
get File Byte 
InputStream fis = null;
ByteArrayOutputStream sb = null;
try {
    fis = inputStream;
    sb = new ByteArrayOutputStream();
    byte[] bytes = new byte[128];
    int n = -1;
    n = fis.read(bytes);
...
byte[]readBytes(InputStream s)
read fully the contents of s and return a byte array holding the result 
if (s == null) {
    throw new IllegalArgumentException("null s");
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] b = new byte[1024];
int n = s.read(b);
while (n != -1) {
    out.write(b, 0, n);
...
StringreadFile(InputStream in, String encoding)
Reads the given input stream to a string content. 
try {
    byte[] b = new byte[in.available()];
    in.read(b);
    return new String(b, encoding);
} finally {
    if (in != null) {

byte[]readFile(InputStream in, int size)
Reads bytes from given input stream with specified length. 
byte[] b = new byte[size];
