Answer 1

//Entity class of the DataTableTwo was not correctly initialized.

List<DataTableOne> listOne = service.ListAll(); //will return 10 records
List<DataTableTwo> listTwo = null;

for(DataTableOne row : listOne){
   
   listTwo.add(new DataTableTwo(row.getIdOne(), 1)); //there are two integer and you can form any how you want.

 }
