How to remove duplicate and sort objects from JSONArray using Java

Question

My JSON is:

[
   {
      \"distance\":32,
      \"stationCode\":\"MIG\",
      \"name\":\"Midghat\",
      \"platforms\":\"2\"
   },
   {
      \"distance\":

There is no direct way to that but you can follow the way mentioned bellow:

1. Transform JsonObject to Java Object list using org.codehaus.jackson.map.ObjectMapper

2. Use a Java Map to make unique (put key = stationCode, javaObject as object)

3. Sort the map data based on distance.
