Description

The list of methods to do Dump Byte Array are organized into topic(s).

Method

void dump(byte[] buffer, int start, int size, PrintStream out)
Prints hex dump of part of byte array to specified stream

StringBuffer sb = new StringBuffer();
int pos = 0;
for (int i = 0; i < size / 16; i++) {
 _dump(buffer, start + pos, 16, out);
 pos += 16;
 out.println();
_dump(buffer, start + pos, size - pos, out);
...

void dump(byte[] data, OutputStream out, boolean closeOutput)
Dump all data in buffer to output stream.

try {
 out.write(data, 0, data.length);
} finally {
 if (closeOutput) {
 out.close();

void dump(final byte[] b, final PrintStream out)
dump

for (int i = 0; i < b.length; ++i) {
 if (i % 16 == 0) {
 out.print(Integer.toHexString(i & 0xFFFF | 0x10000).substring(1, 5) + " - ");
 out.print(Integer.toHexString(b[i] & 0xFF | 0x100).substring(1, 3) + ' ');
 if (i % 16 == 15 || i == b.length - 1) {
 int j;
 for (j = 16 - i % 16; j > 1; --j) {
...

void dump(PrintStream printer, byte[] buffer, int offset, int count)
Dumps a buffer in printable form.

if (count == 0) {
 return;
final int upper_bound = offset + (count / 8 + 1) * 8;
int i = offset;
StringBuffer str = new StringBuffer();
while (i <= upper_bound) {
 int j;
...

void dumpBuffer(final PrintStream out, final String label, final byte[] b)
dump Buffer

dumpBuffer(out, label, b, 0, b.length);

String dumpByteArray(byte[] byteArray)
creates a nice hex-dump of the byte array

if (byteArray == null) {
 return "null";
return dumpInputStream(new ByteArrayInputStream(byteArray));

String dumpByteArray(byte[] bytes)
dump Byte Array

StringBuilder sb = new StringBuilder();
for (int i = 0; i < bytes.length; i++) {
 byte b = bytes[i];
 int iVal = b & 0xFF;
 int byteN = Integer.parseInt(Integer.toBinaryString(iVal));
 sb.append(String.format("%102ドルd: %208ドルd %31ドルc %3$d\n", i, byteN, iVal));
return sb.toString();
...

void dumpBytes(PrintStream printStream, byte bytes[])
dump Bytes

for (int i = 0; i < bytes.length; i++) {
 if (i % 16 == 0)
 printStream.printf("%106ドルX:", i);
 printStream.print(' ');
 if (bytes[i] < 32 || bytes[i] >= 127)
 printStream.print(' ');
 else
 printStream.print((char) bytes[i]);
...

void dumpBytesAsString(ByteArrayOutputStream baos)
dump Bytes As String

byte b[] = baos.toByteArray();
for (byte i : b) {
 System.out.print((char) i);
System.out.println();

void dumpBytesToFile(byte[] bytes, String outputFile)
dump Bytes To File

try {
 BufferedWriter bw = new BufferedWriter(new FileWriter(outputFile));
 for (int i = 0; i < bytes.length; ++i) {
 bw.write(getByteAsAscii(bytes[i]));
 if ((i + 1) % 16 == 0) {
 bw.write("\n");
 bw.close();
} catch (IOException e) {
 e.printStackTrace();
