将一个int数组附加到<Integer>的ArrayList中

Question

Is there a shortcut to add (in fact append ) an array of int to an ArrayList? for the following example

ArrayList<Integer> list=new ArrayList<Integer>();  
    int[] ints={2,4,5,67,8};  

Or do I have to add the elements of ints one by one to list?

Answer 1

Using Arrays.asList(ints) as suggested by others won't work (it'll give a list of int[] rather than a list of Integer ).

The only way I can think of is to add the elements one by one:

    for (int val : ints) {
        list.add(val);
    }

If you can turn your int[] into Integer[] , then you can use addAll() :

    list.addAll(Arrays.asList(ints));
