Add 2 arraylists into 1 with same index value

Question

I know this question is kind of repetitive But still I can't get an answer.
I have 2 arraylists containing name and description respectively as

    final ArrayList<String> arrayOne = new ArrayList<String>(); // containing names
    final ArrayList<String> arraytwo = new ArrayList<String>(); // containing description

I need a view like

I have tried

arraytwo.add(arrayOne);

&

arrayThree.addAll(arrayOne);
arrayThree.addAll(arrayTwo);

But can't a desired arraylist.
Regards

create a POJO with two member variables name and description and then create a custom ArrayList<YourPojo> it would be easy to manage that way, — Satyen Udeshi

POJO class

public class Model
{
    String name;
    String desc;

    public String getName() {
        return name;
    }

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

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        desc = desc;
    }
    }

For Storing to arraylist

ArrayList<Model> arrayModel = new ArrayList<Model>();

      for(int i=0;i<arrayOne.size();i++)
   {
        Model model=new Model();
        model.setName(arrayOne.get(i));
        model.setDesc(arrayTwo.get(i));
        arrayModel.add(model);
   }

If you don't want to create POJO, try this:

List<String> nameList;
List<String> desList;

//for storing
Map<String, String> map = new HashMap<>();
for(int i=0;i<nameList.size();i++) {
    map.put(nameList.get(i), desList.get(i));
}

//for retrieving
for(Map.Entry<String, String> m : map.entrySet())
    String nameListItem = m.getKey();
    String desListItem = m.getValue();
}
