How can you read multiple objects into a single ObjectInputStream?

Question

Before sending a file to a remote machine, I'm sharding it into multiple smaller pieces locally.

Once the file is split into shards, I write the objects using and ObjectOutputStream. Can I read multiple shard objects from file, using a ObjectInputStream, into a single object? I see no immediate way to append to the ObjectInputStream.

So basically, the flow I'm hoping to have would go:

• Shard File
  • Split file into multiple shards
  • Write each shard using ooo.writeObject(shard)
  • (e.g., shard.1, shard.2, shard.3, ...)
• Merge File
  • From a list of shard files, use an ObjectInputStream to read/combine them back into their original object.

Answer 1

Use the same ObjectInputStream and ObjectOutputStream for the entire transmission. Then you can write and read as many objects with them as you like.

OR

Use a new ObjectInputStream per ObjectOutputStream.
