Use List.toArray():

List<String> backList = new ArrayList<>();
backList.add("abc");
backList.add("xyz");
backList.add("pqr");
String[] blist = backList.toArray(new String[backList.size()]);

And use Arrays.toString() to print it:

Log.e("Log","Array in String=" + Arrays.toString(blist));

First store String data into JSONArray.

After convert it into String.

JSONArray backArray=new JSONArray();
for(int i=0;i<backList.size();i++){
    backArray.put(backList.get(i));
}
Log.e("Log","String Formate Array="+backArray.toString());
