How do you serialize an object class in Java?

For serializing the object, we call the writeObject() method of ObjectOutputStream class, and for deserialization we call the readObject() method of ObjectInputStream class. We must have to implement the Serializable interface for serializing the object.

Which of the following class objects is serializable?

Button class implements the Serializable interface, so you can serialize a java. awt. Button object and store that serialized state in a file. Later, you can read back the serialized state and deserialize into a java.

Which of the following class object is serializable in Java?

To make a Java object serializable we implement the java. io. Serializable interface. The ObjectOutputStream class contains writeObject() method for serializing an Object.
