How to Serialize an Object in Java

Step-by-Step Guide

1. 1

   Step 1: Open the Java coding object that requires serialization or create one from scratch.

   In this example, we will call that object “MyObject.” , Just add the following code line at the beginning of the code, replacing the "public class MyObject" line. public class MyObject implements java.io.Serializable , try{ // Serialize data object to a file ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("MyObject.ser")); out.writeObject(object); out.close(); // Serialize data object to a byte array ByteArrayOutputStream bos = new ByteArrayOutputStream() ; out = new ObjectOutputStream(bos) ; out.writeObject(object); out.close(); // Get the bytes of the serialized object byte[] buf = bos.toByteArray(); } catch (IOException e) { } ,,,

   Step 2: Select the object in Java that you want to serialize.

3. 3

   Step 3: Enable object serialization in Java by making the MyObject class to implement the java.io.Serialize interface.

4. 4

   Step 4: Now your object is serializable

5. 5

   Step 5: that means that it can be written by an output stream

6. 6

   Step 6: like this: The following code lines illustrate how to write MyObject (or any serializable object) to a file or disk.

7. 7

   Step 7: It can be read like this: try{ FileInputStream door = new FileInputStream("name_of_file.sav"); ObjectInputStream reader = new ObjectInputStream(door); MyObject x = new MyObject(); x = (MyObject) reader.nextObject(); }catch (IOException e){ e.printStackTrace(); }

8. 8

   Step 8: Execute the serialized object code within the Java program to make sure that it operates effectively (optional).

9. 9

   Step 9: Save and close the serialized object in Java.
