All permutations of ArrayList

I am trying to write a program that returns all permutations of an ArrayList. So far it's only working when using 0, 1, or 2 elements. However I know there is something wrong with my final "else" statement, I just cannot figure out what. This is pretty confusing to me and I'm not quite sure how to go about it...

import java.util.ArrayList;

public class Permutation
{
public static ArrayList<ArrayList<Integer>> permutation(final ArrayList<Integer> list)
{
    ArrayList<Integer> yourList = list;
    return insertTypePermutation(yourList);

}

public static ArrayList<ArrayList<Integer>> insertTypePermutation(ArrayList<Integer> yourList)
{
    ArrayList<Integer> arrayList = new ArrayList<Integer>();

    for(int i = 0; i < yourList.size(); i++)
    {
        arrayList.add(yourList.get(i));
    }

    ArrayList<ArrayList<Integer>> result = new ArrayList<ArrayList<Integer>>();

    if(yourList.size() < 2)
    {
        result.add(yourList);
        return result;
    }
    else if(yourList.size() == 2)
    {
        result.add(yourList);
        result.add(reverse(yourList));
        return result;
    } //problem starts: -----------------------------------------------
    else
    {
        int firstEntry = yourList.get(0);
        yourList.remove(0);
        result = insertTypePermutation(yourList);
        int currResultSize = result.size();
        int currResultElementSize = result.get(0).size();

        for(int i = 0; i < currResultSize; i++)
        {
            for(int j = 0; j <= currResultElementSize; j++)
            {
                ArrayList<Integer> tempResult = result.get(0);
                tempResult.add(j, firstEntry);
                result.add(tempResult);

                if(j == currResultElementSize)
                {
                    result.remove(0);
                }
            }
        }

        return result;
    } //problem ends ^ -------------------------------------------
}

public static ArrayList<Integer> reverse(final ArrayList<Integer> someList)
{
    ArrayList<Integer> tempList = new ArrayList<Integer>();

    for(int i = 0; i < someList.size(); i++)
    {
        tempList.add(someList.get(i));
    }

    int temp = tempList.get(0);
    tempList.remove(0);
    tempList.add(temp);
    return tempList;
}

}
