Save in a file an inventory?

Hello everyone, I am creating a plugin that saves in a file the items in an inventory.
I succeeded, but does not save the name of 'items.
This is my code:
YamlConfiguration fileyml YamlConfiguration = new ();
c.set ("inv.content", inv.getContents ());
c.save (new File ("plugins / test", playername +. "yml"));
How could I do?
P.S. Sorry for my English, but I'm Italian XD

 

You could always encode it with base64, and back. It works quite well and it's what I use whenever I have to store inventories.

Here's an example to encode it( Not actual working code ):

PHP:

public String toBase64(inventory) {
    try {
         ByteArrayoutputstream str = new bytestream()
         BukkitObjectoutputstream data = new bukkitobject;
     
          data.writeInt(inventory.getSize());
      
           for (int i = 0; i < inventory.size; i++ {
               data.writeObject(inventory.getitem(i))
           }

           data.close();
           return base64coder.encodelines(outputstream.tobytearray();

    } catch (Exception e) {
          e.printstack()
    }
}

aaaand to get it back:

PHP:

public Inventory fromBase(string data) {
    ByteArrayinputstream stream = new bytearrayinputstream(base64coder.decodeLines(data))

   Bukkitobjectinputstream data = new bukkitobjectinputstream(stream)

   Inventory inv = bukkit.createinventory(null, data.readInt())

   for (int i = 0; i < inventory.size; i++) {
        inventory.setitem(i, (inv) data.readObject()
    }


    data.close();
    return inventory;

}
