Java List to Map Conversion: Efficiently Transform String Lists

To convert a 'data' list into a map, you can use the following code:

List<String> data = Org.getResult().getData();
Map<Integer, String> map = new HashMap<>();

for (int i = 0; i < data.size(); i++) {
    map.put(i, data.get(i));
}

In this code, a 'HashMap' is created to store the data from the list. The index of each element in the list is used as the key in the map, and the corresponding element is stored as the value.
