I'll just give a little Jackson example:

First create a data holder which has the fields from JSON string

// imports

// ...

@JsonIgnoreProperties(ignoreUnknown = true)

public class MyDataHolder {

    @JsonProperty("name")

    public String mName;



    @JsonProperty("url")

    public String mUrl;

}

And parse list of MyDataHolders

String jsonString = // your json

ObjectMapper mapper = new ObjectMapper();

List<MyDataHolder> list = mapper.readValue(jsonString, 

    new TypeReference<ArrayList<MyDataHolder>>() {});

Using list items

String firstName = list.get(0).mName;

String secondName = list.get(1).mName;

public static void main(String args) throws JSONException {

    String str = "[{"name":"name1","url":"url1"},{"name":"name2","url":"url2"}]";



    JSONArray jsonarray = new JSONArray(str);





    for(int i=0; i<jsonarray.length(); i++){

        JSONObject obj = jsonarray.getJSONObject(i);



        String name = obj.getString("name");

        String url = obj.getString("url");



        System.out.println(name);

        System.out.println(url);

    }   

}   

Output:

name1

url1

name2

url2

Create a class to hold the objects.

public class Person{

   private String name;

   private String url;

   //Get & Set methods for each field

}

Then deserialize as follows:

Gson gson = new Gson();

Person person = gson.fromJson(input, Person.class); //input is your String

Reference Article: http://blog.patrickbaumann.com/2011/11/gson-array-deserialization/

In this example there are several objects inside one json array. That is,

This is the json array: [{"name":"name1","url":"url1"},{"name":"name2","url":"url2"},...]

This is one object: {"name":"name1","url":"url1"}

Assuming that you have got the result to a String variable called jSonResultString:

JSONArray arr = new JSONArray(jSonResultString);



  //loop through each object

  for (int i=0; i<arr.length(); i++){



  JSONObject jsonProductObject = arr.getJSONObject(i);

  String name = jsonProductObject.getString("name");

  String url = jsonProductObject.getString("url");





}

@Stebra See this example. This may help you.

public class CustomerInfo 

{   

    @SerializedName("customerid")

    public String customerid;

    @SerializedName("picture")

    public String picture;



    @SerializedName("location")

    public String location;



    public CustomerInfo()

    {}

}

And when you get the result; parse like this

List<CustomerInfo> customers = null;

customers = (List<CustomerInfo>)gson.fromJson(result, new TypeToken<List<CustomerInfo>>() {}.getType());

A few great suggestions are already mentioned.
Using GSON is really handy indeed, and to make life even easier you can try this website
It's called jsonschema2pojo and does exactly that:

You give it your json and it generates a java object that can paste in your project.
You can select GSON to annotate your variables, so extracting the object from your json gets even easier!

My case
Load From Server Example..

int jsonLength = Integer.parseInt(jsonObject.getString("number_of_messages"));

            if (jsonLength != 1) {

                for (int i = 0; i < jsonLength; i++) {

                    JSONArray jsonArray = new JSONArray(jsonObject.getString("messages"));

                    JSONObject resJson = (JSONObject) jsonArray.get(i);

                    //addItem(resJson.getString("message"), resJson.getString("name"), resJson.getString("created_at"));

                }

Hope it help

Create a POJO Java Class for the objects in the list like so:

class NameUrlClass{

       private String name;

       private String url;

       //Constructor

       public NameUrlClass(String name,String url){

              this.name = name;

              this.url = url; 

        }

}

Now simply create a List of NameUrlClass and initialize it to an ArrayList like so:

List<NameUrlClass> obj = new ArrayList<NameUrlClass>;

You can use store the JSON array in this object

obj = JSONArray;//[{"name":"name1","url":"url1"}{"name":"name2","url":"url2"},...]
