Method

voiddumpClass(String file, byte[] bytes)
Dump some bytes into the specified file. 
File f = new File(file);
try {
    FileOutputStream fos = new FileOutputStream(f);
    fos.write(bytes);
    fos.flush();
    fos.close();
} catch (IOException ioe) {
    ioe.printStackTrace();
...
byte[]dumpFileIntoByteArray(File f)
dump File Into Byte Array 
ByteArrayOutputStream byteStream = null;
BufferedInputStream fileStream = null;
try {
    byteStream = new ByteArrayOutputStream();
    fileStream = new BufferedInputStream(new FileInputStream(f));
    int data = -1;
    while ((data = fileStream.read()) != -1) {
        byteStream.write(data);
...
StringdumpHex(byte[] data)
Dump an the content of an array of byte as a hex dump 
StringBuffer result = new StringBuffer();
ByteArrayInputStream buf = new ByteArrayInputStream(data);
int lineBytes = 0;
int i;
byte[] b = new byte[16];
String s;
while (buf.available() > 0) {
    b[lineBytes] = (byte) buf.read();
...
voiddumpHex(PrintStream out, byte[] data, int offset, int length)
Dumps an array of byte to the output string as a sequence of hexadecimal digits. 
if ((offset + length) > data.length)
    return;
int cnt = 0;
while (length > 0) {
    byte b = data[offset];
    out.print("0x");
    out.print(Integer.toHexString((b >> 4) & 0xf));
    out.print(Integer.toHexString(b & 0xf));
...
StringdumpHex(String _string, String _encoding)
dump Hex 
StringBuilder sb = new StringBuilder();
byte[] bytes = _string.getBytes(_encoding);
for (int i = 0; i < bytes.length; i++) {
    sb.append(Integer.toHexString(bytes[i] & 0xff));
    if (i < bytes.length - 1) {
        sb.append(" ");
return sb.toString();
StringdumpHex(String value, String encoding)
dump Hex 
StringBuilder sb = new StringBuilder();
byte[] bytes = value.getBytes(encoding);
for (int i = 0; i < bytes.length; i++) {
    sb.append(Integer.toHexString(bytes[i] & 255));
    if (i < bytes.length - 1) {
        sb.append(' ');
return sb.toString();
