java array to arraylist

                                    List<String> list = new ArrayList<>();
list.add("a");
list.add("ab");
list.add("abc");
list.add("abcd");
// convert
String[] array = list.toArray();

                                    ArrayList<String> ArrayLister=new ArrayList<>(){ArrayLister.add("Hi")};
String[] array=ArrayLister.toArray(String[]);

                                    new ArrayList<>(Arrays.asList(array))

                                    Integer[] arr = new Integer[al.size()]; 
  
        // ArrayList to Array Conversion 
        for (int i = 0; i < al.size(); i++) 
            arr[i] = al.get(i); 

                                    List<Element> list = Arrays.asList(array);
