How to split array list into equal parts?

Question

Is there anyway to split ArrayList into different parts without knowing size of it until runtime? I know there is a method called:

list.subList(a,b);
         


        

Answer 1

generic function :

public static  ArrayList chunks(ArrayList bigList,int n){
    ArrayList chunks = new ArrayList();

    for (int i = 0; i < bigList.size(); i += n) {
        T[] chunk = (T[])bigList.subList(i, Math.min(bigList.size(), i + n)).toArray();         
        chunks.add(chunk);
    }

    return chunks;
}

enjoy it~ :)
