How can I generate a list or array of sequential integers in Java?

Question

Is there a short and sweet way to generate a List, or perhaps an Integer[] or int[], with sequential values from some

Answer 1

This is the shortest I could find.

List version

public List makeSequence(int begin, int end)
{
    List ret = new ArrayList(++end - begin);

    for (; begin < end; )
        ret.add(begin++);

    return ret;
}

Array Version

public int[] makeSequence(int begin, int end)
{
    if(end < begin)
        return null;

    int[] ret = new int[++end - begin];
    for (int i=0; begin < end; )
        ret[i++] = begin++;
    return ret;
}
