Map of maps - how sort inner map with lambda?

I have a map like this:

Map<String,Map<String,String>>

And I need to sort the second map, so I try something like this:

ArrayList<ArrayList<String>> response = new ArrayList<>();

response.add(new ArrayList<String>() {{ add("STATE1"); add("COB2"); add("1"); }});
response.add(new ArrayList<String>() {{ add("STATE1"); add("COB125"); add("3");}});
response.add(new ArrayList<String>() {{ add("STATE1"); add("COB55"); add("4");}});
response.add(new ArrayList<String>() {{ add("STATE2"); add("UI5"); add("100");}});

Supplier<TreeMap<String, String>> typeMap = () -> new TreeMap<>(Comparator.naturalOrder());

Object result = response.stream().collect(groupingBy((ArrayList p) -> p.get(0).toString(), Collectors.toMap(
(ArrayList p) -> p.get(1).toString(),
(ArrayList p) -> p.get(2).toString(), (u, v) -> v,typeMap)));

Map<String, Map<String, String>> finalMap = (Map<String, Map<String, String>>) result;

finalMap = STATE1 => {COB125=3, COB2=1, COB55=4}, STATE2 => {UI5=100}

I need different sort type, I tried with the Comparator.naturalOrder() But I need:

expectedMap STATE1 => {COB2=3, COB55=1, COB125=4}, STATE2 => {UI5=100}
