how do i return an array and a linked list?

Question about the task

Under discussion

public class Solution {
    public static Object createArrayList() {
        ArrayList<Cat> cats = new ArrayList<>();

        return ArrayList;

    }

    public static Object createLinkedList() {
        //write your code here

    }

    public static void main(String[] args) {
       LinkedList llobj = new LinkedList();

       return LinkedList;
    }
}

package com.codegym.task.task08.task0807; import java.util.*; /* LinkedList and ArrayList */ public class Solution { public static Object createArrayList() { ArrayList<Cat> cats = new ArrayList<>(); return ArrayList; } public static Object createLinkedList() { //write your code here } public static void main(String[] args) { LinkedList llobj = new LinkedList(); return LinkedList; } }

First off, line 12, you can't create a list of Cat objects if that class doesn't exist; you would first have to create the Cat class. Try changing it to Integer or String. Line 14 should be:

return cats;

i.e. the ArrayList you've created in the method Then, do the exact same thing in the createLinkedList() method, except every time you write "ArrayList", write "LinkedList" instead. Finally, get rid of everything in the main method.
