How to merge 2 arraylists to 1 in android java

Mix, merge 2 arraylists into 1 ArrayList string in android java




You can merge 2 ArrayLists into one in android java easily with the help of this code below

First, initialize the ArrayLists, here are 2 example ArrayLists,

ArrayList<String> array1= gson.fromJson(jsonLink, new TypeToken<ArrayList<String>>() {
          }.getType());

ArrayList<String> array2= gson.fromJson(jsonTitle, new TypeToken<ArrayList<String>>() {
          }.getType());



          List<String> mergedList = new ArrayList();
          mergedList.addAll(array1);
          mergedList.addAll(array2);

 

Array1 and array2 are different ArrayLists, we now merged the 2 into 1 to a new arraylist, the mergedList is the new arraylist

 

Another Example

Here is another ArrayList merging example

ArrayList<String> array1 = new ArrayList<String>();
ArrayList<String> array2 = new ArrayList<String>();


   List<String> newlist = new ArrayList();{
   newlist.addAll(array1);
   newlist.addAll(array2);
