Solved Saving a hashmap

I am wanting to save the following hashmap:

Code:

HashMap<Player, Inventory> storedInv = new HashMap<Player, Inventory>();

The reason I wish to save them is because I don't want the inventory to be lost due to a server restart (I am taking the inventory away when they login, then returning it). I had no idea how to save an inventory to a file, if some assistance could be provided, that would be great.

Not sure if this is outdated, but I made that 2 years ago. If I made something like this now, it'd probably be done in a different way, and look more clean in the config, e.g. My own custom ItemStack serialization.

 

@KingFaris11 Thanks, I'll see if this works .

 

If it does/did, please mark this thread as solved.
