How to return a specific list of pairs from an arraylist in Java

import java.util.ArrayList;

public class Main {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        int[] list = {0,1,2,3};
        int num = 5;
        ArrayList<int[]> results = getPairs(list, num);
        for (int[] tmp : results) {
            System.out.println("(" + tmp[0] + ","+ tmp[1] + ")");
        }

    }

    private static ArrayList<int[]> getPairs(int[] list, int num) {
        ArrayList<int[]> results = new ArrayList<int[]>();
        int len = list.length;
        int index = 0;
        for (int i = 0; i < num; i++) {
            if ((index + 1) >= len) {
                results.add(new int[]{list[index], list[0]});
                index = 0;
            }
            else {
                results.add(new int[]{list[index], list[index + 1]});
                ++index;
            }
        }
        return results;
    }
}
