Method

byte[]inputStreamToByteArray(InputStream is)
input Stream To Byte Array 
ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
try {
    int ch = -1;
    while ((ch = is.read()) != -1) {
        byteStream.write(ch);
    return byteStream.toByteArray();
} finally {
...
byte[]inputStreamToByteArray(InputStream is)
Generates byte array with contents of a stream 
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] bytes = new byte[1024];
int length;
while ((length = is.read(bytes)) != -1) {
    baos.write(bytes, 0, length);
return baos.toByteArray();
byte[]inputStreamToByteArray(InputStream is)
input Stream To Byte Array 
ByteArrayOutputStream os = null;
try {
    os = new ByteArrayOutputStream();
    byte[] buffer = new byte[0xFFFF];
    for (int len; (len = is.read(buffer)) != -1;) {
        os.write(buffer, 0, len);
    os.flush();
...
byte[]inputStreamToByteArray(InputStream is)
Read the ARC record content into a byte array. 
ByteArrayOutputStream baos = new ByteArrayOutputStream();
BufferedInputStream buffis = new BufferedInputStream(is);
BufferedOutputStream buffos = new BufferedOutputStream(baos);
byte[] tempBuffer = new byte[BUFFER_SIZE];
int bytesRead;
while ((bytesRead = buffis.read(tempBuffer)) != -1) {
    buffos.write(tempBuffer, 0, bytesRead);
buffis.close();
buffos.flush();
buffos.close();
return baos.toByteArray();
byte[]inputStreamToByteArray(InputStream is)
input Stream To Byte Array 
ByteArrayOutputStream bout = new ByteArrayOutputStream(4096);
byte[] buf = new byte[4096];
int len = 0;
while ((len = is.read(buf)) != -1) {
    bout.write(buf, 0, len);
bout.close();
return bout.toByteArray();
...
byte[]inputStreamToByteArray(InputStream stream)
Reads the contents of an stream until exhausted and converts contents to an array of bytes. 
if (stream == null) {
    return new byte[] {};
byte[] buffer = new byte[1024];
ByteArrayOutputStream output = new ByteArrayOutputStream();
boolean error = false;
try {
    int numRead = 0;
...
ByteArrayOutputStreaminputStreamToByteArrayOutputStream(final InputStream is)
Read from an InputStream and return it as a ByteArrayOutputStream . 
final BufferedReader in = new BufferedReader(new InputStreamReader(is));
final ByteArrayOutputStream out = new ByteArrayOutputStream();
final int pageSize = 1024;
final byte[] buf = new byte[pageSize];
int ret = is.read(buf, 0, pageSize);
while (ret > 0) {
    final byte[] bufPage = new byte[ret];
    for (int i = 0; i < ret; i++) {
...
byte[]inputStreamToBytes(final InputStream aInputStream)
Converts an input stream into a byte array 
if (aInputStream == null) {
    return null;
final ByteArrayOutputStream outStream = new ByteArrayOutputStream();
final byte[] buffer = new byte[8192];
int read = 0;
do {
    read = aInputStream.read(buffer);
...
byte[]inputStreamToBytes(final InputStream ins)
Takes a 'InputStream' and returns a byte array. 
byte[] ret = null;
try {
    int len = 0;
    final byte[] buf = new byte[2048];
    final ByteArrayOutputStream out = new ByteArrayOutputStream();
    while ((len = ins.read(buf)) != -1) {
        out.write(buf, 0, len);
    ret = out.toByteArray();
} catch (IOException e) {
return ret;
byte[]inputStreamToBytes(InputStream in)
Converts an InputStream to a byte[] 
ByteArrayOutputStream out = new ByteArrayOutputStream();
try {
    byte[] buffer = new byte[1024];
    int len;
    while ((len = in.read(buffer)) != -1) {
        out.write(buffer, 0, len);
} catch (Exception e) {
