[1.10]How to turn this data container into configuration?

[TheAwesomeGem]

This is the data container I have:

 

public static Map<Integer, List<Pair<String, Integer>>> warriorEquipmentMainHandMap = new HashMap<Integer, List<Pair<String, Integer>>>()
        {{
            put(1, new ArrayList<Pair<String, Integer>>()
            {{
                add(new Pair<>("wooden_axe", 70));
                add(new Pair<>("stone_axe", 30));
            }});

            put(2, new ArrayList<Pair<String, Integer>>()
            {{
                add(new Pair<>("wooden_axe", 20));
                add(new Pair<>("stone_axe", 70));
                add(new Pair<>("iron_axe", 10));
            }});

            put(3, new ArrayList<Pair<String, Integer>>()
            {{
                add(new Pair<>("stone_axe", 70));
                add(new Pair<>("iron_axe", 30));
            }});
        }};

 

Basically I want to turn that into this on the config:

 

warriorequipmentmainhand{
	
	1{
		"wooden_axe":70,
		"stone_axe":30
	}
	
	2{
		"wooden_axe":20,
		"stone_axe":70,
		"iron_axe":10
	}
	
	3{
		"stone_axe":70,
		"iron_axe":30
	}
}

 

How would I go about doing that since I don't see a list of keyvalpair on configuration?

Well, managed to solve it by myself using string delimiter. Is there any string length limit for a getStringArray?
