TRY IT OUT: Deserializing Objects
You can read the file containing Junk objects with the following code:

import java.io.*;
import java.nio.file.*;

class DeserializeObjects {
public static void main(String args[]) {
Path file = Paths.get(System.getProperty("user.home")).
resolve("Beginning Java
Stuff").resolve("JunkObjects.bin");
if(Files.notExists(file)) {
System.out.printf("\nFile %s does not exist.", file);
System.exit(1);

}

int objectCount = 0; // Number of objects

read

try (ObjectInputStream objectIn =
new ObjectInputStream(new BufferedInputStream(

Files.newInputStream(file)))){
// Read from the stream until we hit the end
Junk object = null; // Stores an object

reference
while(true) {
object = (Junk)objectIn.readObject(); // Read an object
++objectCount; // Increment the count

System.out.println(object); // Output the object

}

} catch(EOFException e) { // This will execute when we reach EOF
System.out.println("EOF reached. "+ objectCount + " objects
read.");

} catch(IOException|ClassNotFoundException e) {
e.printStackTrace();

}

}

}
