Java Utililty Methods OutputStream Write Byte Array

void writeBytes(byte[] data, OutputStream out)
write Bytes

transfer(new ByteArrayInputStream(data), out);

void writeBytes(byte[] data, OutputStream out)

Writes a given bytes to a stream.

ByteArrayInputStream in = new ByteArrayInputStream(data);
byte[] buffer = new byte[1024];
for (int n; (n = in.read(buffer)) > 0;) {
 out.write(buffer, 0, n);

void writeBytes(byte[] data, OutputStream stream)
Writing byte array to stream

stream.write(data);

void writeBytes(int[] data, OutputStream out)
Writes data from the integer array to disk as raw bytes.

byte[] b = new byte[4];
for (int word : data) {
 b[0] = (byte) ((word >>> 24) & 0xFF);
 b[1] = (byte) ((word >>> 16) & 0xFF);
 b[2] = (byte) ((word >>> 8) & 0xFF);
 b[3] = (byte) ((word >>> 0) & 0xFF);
 out.write(b);

void writeBytes(OutputStream os, byte[] b)
write Bytes

os.write(b, 0, b.length);

void writeBytes(OutputStream os, byte[] b)
write Bytes

os.write(toBytes(b.length));
if (b.length > 0) {
 os.write(b);
os.flush();

void writeBytes(OutputStream out, byte[] data)
Write a byte array.

writeVarInt(out, data.length);
out.write(data);

void writeBytes(OutputStream output, Object value)
write Bytes

try {
 try (ObjectOutputStream out = new ObjectOutputStream(output)) {
 out.writeObject(value);
} catch (IOException e) {
 throw new RuntimeException(e);

void writeBytes(OutputStream outputStream, byte[] data)
write Bytes

assert outputStream != null;
try {
 outputStream.write(data);
} finally {
 outputStream.close();

boolean writeBytesToStream(byte[] bytes, OutputStream os, boolean printStackTraceOnError)
Write the contents of a byte array to an OutputStream without needing to worry about exceptions.

try {
 os.write(bytes);
 return true;
} catch (IOException e) {
 if (printStackTraceOnError) {
 e.printStackTrace();
 return false;
