I want to convert this into a List of custom object type using Gson

Here's my POJO in

public class RazorpayNetbanking {
@Expose
private String name;
@Expose
private String value;

public String getName() {
    return this.name;
}

public void setName(String name) {
    this.name = name;
}

public String getValue() {
    return this.value;
}

public void setValue(String value) {
    this.value = value;
}
}

Answer 1

Since you cannot guess the keys, you should iterate over them:

val json: JsonObject // assuming
json.keySet().forEach {  key ->
    val value = json.get(key).asString
    // add to list (key, value)
}

This will only for keys but I think you got the idea.

Answer 2

You should use a map and you can convert it to a list easily.

EDIT: I don't know if gson support list of pair. Maybe it can work...
