Gson parse Json with array

Question

I am having some trouble building a class which will parse out gson as I expect it to.

I created a class.

public class JsonObjectBreakDown {
    public         


        

Answer 1

The problem here is that you have an array of arrays of arrays of floating point numbers in your JSON. Your class should be

public class JsonObjectBreakDown {
    public String type; 
    public List<List<float[]>> coordinates = new ArrayList<>();
}

Parsing with the above and trying

System.out.println(p.coordinates.size());
System.out.println(p.coordinates.get(0).size());
System.out.println(Arrays.toString(p.coordinates.get(0).get(0)));

yields
