Which Input Stream is Used for Deserialization in Java?

ObjectInputStream is the correct input stream for deserialization in Java. It allows you to read serialized objects from a file or other input source and reconstruct them in memory.

Here's a breakdown of why the other options are incorrect:

• FileWriter: Used for writing text data to files, not for reading serialized objects.
• FileReader: Used for reading text data from files, not for reading serialized objects.
• ObjectOutputStream: Used for writing serialized objects to files or other output sources. It's the counterpart to ObjectInputStream.
