The list of methods to do Object Serialize are organized into topic(s).

Method

byte[] serialize(@Nonnull T object)
Serialize an object.

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
ObjectOutput objectOutput = null;
try {
 objectOutput = new ObjectOutputStream(byteArrayOutputStream);
 objectOutput.writeObject(object);
 return byteArrayOutputStream.toByteArray();
} finally {
 try {
...

byte[] serialize(@Nullable final Object obj)
serialize

if (obj == null) {
 return null;
final ByteArrayOutputStream os = new ByteArrayOutputStream(1024);
try {
 final ObjectOutputStream out = new ObjectOutputStream(os);
 try {
 out.writeObject(obj);
...

byte[] serialize(@Nullable Object value)
Turns an object into a byte array.

if (value == null) {
 return null;
ByteArrayOutputStream objectBytes = new ByteArrayOutputStream();
try (ObjectOutputStream oos = new ObjectOutputStream(objectBytes)) {
 oos.writeObject(value);
} catch (IOException e) {
 throw new IllegalArgumentException("Unable to serialize: " + value, e);
...

void serialize(File outFile, Object source)
serialize

try {
 if (!outFile.getParentFile().exists() && outFile.getParentFile().mkdirs()) {
 if (!outFile.exists() && outFile.createNewFile()) {
 FileWriter writer = new FileWriter(outFile);
 writer.write(GSON.toJson(source));
 writer.flush();
...

byte[] serialize(final @Nonnull Object obj)
serialize

try {
 ByteArrayOutputStream b = new ByteArrayOutputStream();
 ObjectOutputStream o = new ObjectOutputStream(b);
 o.writeObject(obj);
 return b.toByteArray();
} catch (IOException e) {
 e.printStackTrace();
return new byte[0];

void serialize(final File file, final Object o)
serialize

ObjectOutput out = null;
try {
 out = new ObjectOutputStream(new FileOutputStream(file));
 out.writeObject(o);
} finally {
 if (out != null) {
 out.close();

Byte[] serialize(final Object object)
serialize

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
objectOutputStream.writeObject(object);
return toComposite(byteArrayOutputStream.toByteArray());

void serialize(final Object object, final File file)
serialize

try {
 final FileOutputStream fileOut = new FileOutputStream(file);
 final ObjectOutputStream out = new ObjectOutputStream(fileOut);
 out.writeObject(object);
 out.close();
 fileOut.close();
} catch (final IOException e) {
 throw new RuntimeException(e);
...

byte[] serialize(final Serializable obj)

Serializes an Object to a byte array for storage/serialization.

final ByteArrayOutputStream baos = new ByteArrayOutputStream(512);
serialize(obj, baos);
return baos.toByteArray();

byte[] serialize(final Serializable object)
Serialize an object.

final ByteArrayOutputStream outBytes = new ByteArrayOutputStream();
serialize(object, outBytes);
return outBytes.toByteArray();
