add values into section in recyclerView

i followed this question's answer for adding sections in my recyclerView

for adding the sections we have to provide the index for section like this :

//Sections
sections.add(new SimpleSectionedRecyclerViewAdapter.Section(0,"Section 1"));
sections.add(new SimpleSectionedRecyclerViewAdapter.Section(5,"Section 2"));

so the section 1 will be at index 0 and section 2 will be at index 5

now i have dataset of ChannelsInformation and channelInformation class is :

public class ChannelsInformation {
String id,channelName;
boolean isSelected , isfavorite;
}

so my question is that what i have to do for adding my dataSet into different sections ? suppose i have a data 

<id = 1 , channelName = channelName1 , isSelcted = false , isfavorite = true >
2 , channelName2 , false , false 
3 , channelName3 , false , true 
4 , channelName4 , false , false

so the above is a demo of some data now i want to add that data into my recyclerView according two isFavorite field , after adding the data in recylerView it should look like this :

section 1
1 - channelName1
3 - channelName3
section 2
2 - channelName2
4 - channelName4

any idea what i have to do for adding my data in a form so that it'll organise as the above example ?

this is how am populating the data into my recyclerView (on my fragment class) :

    public static List<ChannelsInformation> getData(){

    List<ChannelsInformation> data = new ArrayList<>();

    for (int i = 0 ; i<channelsArray.size() && i<channelsIDArray.size() ; i++ ){

        ChannelsInformation current  = new ChannelsInformation();
        current.channelName = channelsArray.get(i);
        current.id = channelsIDArray.get(i);
        current.isFavorite = channelIsFavoriteArray.get(i);

        data.add(current);
    }

    return  data;

}

any idea how am gonna do that ? any hint or guidance will be highly appreciated

if code is not sufficient then please let me know i'll update it

you can sort your list on the basis of boolean "isfavorite" as follows:

public class ChannelsInformation implements Comparable<ChannelsInformation> {
    String id, channelName;
    boolean isSelected, isfavorite;



    @Override
    public int compareTo(ChannelsInformation o) {
        int b1 = this.isfavorite ? 1 : 0;
        int b2 = o.isfavorite ? 1 : 0;

        return b2 - b1;
    }

}

And then call Collections.sort(data); after setting your arraylist.
