Reliably convert any object to String and then back again

Question

Is there a reliable way to convert any object to a String and then back again to the same Object? I\'ve seen some examples of people converting them using toString()

Answer 1

Yes, it is Serialization You can use, ObjectInputStream.readObject and ObjectOutputStream.writeObject. Please see below example:

MyClass myClass = new MyClass();
FileOutputStream fileStream = new FileOutputStream("myObjectFile.txt");
ObjectOutputStream os = new ObjectOutputStream(fileStream);
os.writeObject(os);
os.close();

FileInputStream fileInStream = new FileInputStream("myObjectFile.txt");
ObjectInputStream ois = new ObjectInputStream(fileInStream);
MyClass myClass2 = ois.readObject();
ois.close();
