Gson I can't deserialize an array which contains latitude and longitude - arrays

Question

I'm deserializing Json from an air quality site that has an array with latitude and longitude. The Json looks like this:
{
"geo": [
-36.05035,
146.942
],
"name": "Albury South-west Slopes, Australia",
"url": "https://aqicn.org/city/australia/nsw/albury/south-west-slopes"
}
I have written a custom deserializer which does the job but I can't deserialize "geo": [-36.05035, 146.942].
My code looks like this:
public static class City {
private Geo[] geo;
private String name;
private String url;
public Geo[] getGeo() {
return geo;
}
public void setGeo(Geo[] geo) {
this.geo = geo;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
}
public static class Geo {
//what are the getters and setters for an array with no names just numbers?
}
It has me stumped
Thanks Phil

Answer 1

You can use Jackson with custom deserializer. For reference, you can look at Custom deserializer

Answer 2

Let geo be a List<Double> instead of a nested class:
public static class City {
private List<Double> geo;
private String name;
private String url;
public List<Double> getGeo() {
return geo;
}
public void setGeo(List<Double> geo) {
this.geo = geo;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
}
Deserialization should then be straightforward:
String json = "{\"geo\":[-36.05035,146.942],\"name\": \"Albury South-west Slopes, Australia\",\"url\": \"https://aqicn.org/city/australia/nsw/albury/south-west-slopes\"}";
City city = new Gson().fromJson(json, City.class);
