Thread: Printing Array

I'm doing the following exercise: Write a Java program to merge all overlapping Intervals from a given collection of intervals.
I'm not getting my array printed as I want too. It gives me the address of memory instead I think.

Here is my code :

import java.util.*;
import java.util.LinkedList;
 
public class overlappingIntervals {
 
    public static class Interval {
        int start;
        int end;
 
        Interval(int s, int e) {
            this.start = s;
            this.end = e;
        }
    }
 
    public static int[][] merge(int[][] intervals) {
        if (intervals.length <= 1) {
            return intervals;
        }
        LinkedList<Interval> ll = new LinkedList<>();
        for (int[] temp : intervals) {
            ll.add(new Interval(temp[0], temp[1])); // got the error here
        }
        Collections.sort(ll, new Comparator<Interval>() {
            public int compare(Interval a, Interval b) {
                return a.start - b.start;
            }
        });
 
        LinkedList<Interval> result = new LinkedList<>();
        for (Interval curr : ll) {
            if (result.isEmpty() || result.getLast().end < curr.start) {
                result.add(curr);
            } else {
                result.getLast().end = Math.max(curr.end, result.getLast().end);
            }
        }
        int[][] res = new int[result.size()][2];
        int count = 0;
        for (Interval temp : result) {
            res[count][0] = temp.start;
            res[count][1] = temp.end;
            count++;
        }
        return res;
    }
 
    public static void main(String[] args) {
        int[][] intervalNumbers = { { 1, 3 }, { 2, 6 }, { 8, 10 }, { 15, 18 } };
        System.out.println(Arrays.toString(merge(intervalNumbers))); // it does print [[I@156643d4, [I@123a439b, [I@7de26db8] - I don't want that, I want the actual value.
    }
}

How to fix this?
