Method

byte[]readFileEx(String... file)
read File Ex 
ByteArrayOutputStream baos = new ByteArrayOutputStream();
for (String f : file) {
    FileInputStream fis = null;
    try {
        fis = new FileInputStream(f);
        byte[] buf = new byte[4096];
        int cnt;
        while ((cnt = fis.read(buf)) > 0) {
...
byte[]readFileFully(File file)
read File Fully 
byte[] buffer = new byte[BUFFER_SIZE];
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
FileInputStream inStream = null;
try {
    inStream = new FileInputStream(file);
    int readSize = 0;
    while ((readSize = inStream.read(buffer)) != -1) {
        outStream.write(buffer, 0, readSize);
...
byte[]readFileInByteArray(String aFileName)
faz a leitura de um arquivo especifico em um array de byte. 
File file = new File(aFileName);
FileInputStream fileStream = new FileInputStream(file);
try {
    int fileSize = (int) file.length();
    byte[] data = new byte[fileSize];
    int bytesRead = 0;
    while (bytesRead < fileSize) {
        bytesRead += fileStream.read(data, bytesRead, fileSize - bytesRead);
...
byte[]readFileRaw(File file)
read File Raw 
ByteArrayOutputStream os = new ByteArrayOutputStream();
FileInputStream is = new FileInputStream(file);
byte[] buf = new byte[1024];
int ret;
while ((ret = is.read(buf)) != -1)
    os.write(buf, 0, ret);
is.close();
return os.toByteArray();
...
byte[]readFileToBinary(File lessCSS)
read File To Binary

    int bytesRead = -1;
    while ((bytesRead = input.read(buffer)) != -1) {
        byteStream.write(buffer, 0, bytesRead);
...
byte[]readFileToByteArray(File file)
Reads the contents of a file into a byte array. 
InputStream in = null;

    in = openInputStream(file);
    return toByteArray(in, file.length());
} finally {
    closeQuietly(in);
byte[]readFileToByteArray(File file)
read File To Byte Array

} finally {
    closeQuietly(in);
byte[]readFileToByteArray(String file)
Reads a file storing intermediate data into an array. 
InputStream in = null;
byte[] buf = null; 
int bufLen = 20 * 1024 * 1024;
try {
    in = new BufferedInputStream(new FileInputStream(file));
