How to give player multiple dynamic reward via the config files

I have a config.yml file setup like this:

Code:

'0':
    rewards:
        '0':
            type: item
            object:
                id: 264
                name: Diamond
            amount: 5
        '1':
            type: item
            object:
                id: 3
                name: Dirt
            amount: 64
'1':
    rewards:
        '0':
            type: item
            object:
                id: 24
                name: Sandstone
            amount: 30
        '1':
            type: item
            object:
                id: 1
                name: Stone
            amount: 64
            

I want to get all the data for each reward in one of the reward nodes, so I can give the player the amount of the item defined.

I know i can do this with a lot of iteration and .get() functions from the config but this is EXTREMELY inefficient.

 

It may be faster if you do all the loading into a hashmap<integer,customclass> and pull out exactly the information you want, rather than scanning through the whole thing every time.

 

How would I put this into a hashmap?

getValues()?

 

Here is some pseudo code since I don't have an editor on this laptop (i'm in class).

Code:

public hashmap<string,customclass> myhashmap = new hashmap<string,customclass>();

for string id : getconfig.getkeys(false){
    for string rewardid : getconfig.getconfigurationsection(id + ".rewards").getkeys(false){
        
        // use .get* to retrieve the value you want
        
        customclass rewardinfo = new customclass(type,objectid, objectname, amount);
        myhashmap.put(id,rewardinfo);
    }
}
