who knows when we learned array? what lesson?

Question about the task

Under discussion

did i miss array lesson?

1. In the Cat class, add the public static ArrayList<Cat> variable cats.
2. Each time a new cat (new Cat object) is created, add it to the variable cats. Create 10 Cat objects.
3. The printCats method should display all cats on the screen. You need to use the variable cats.

Requirements:

Add the public static ArrayList<Cat> variable cats to the Cat class.
The variable cats must be initialized.
The main method should create 10 Cat objects (use the Cat() constructor).
The main method must add all the created cats to the variable cats.
The printCats method should display all the cat objects in the variable cats. Each on a new line.

package com.codegym.task.task06.task0614; import java.util.ArrayList; /* Static cats */ public class Cat { int i;//write your code here public Cat() { } public static void main(String[] args) { //write your code here printCats(); } public static void printCats() { //write your code here } }

You already asked that question and Gellert answered it. Deleting the post cause the answer isn't to your liking (or for whatever reason) is not really helpful. I doubt others will care to help if you honor their effort with kicking the answer out of the internet. In this task arrays are not (really) involved. The requirements talk about an ArrayList and that hides the array from the class user (you). So you should know about ArrayList but do not need to know about arrays. If a topic has not been touched then you may try to find out about in books or on related websites. If a task is to difficult, just move on and try later again. Some tasks anticipate future lessons. So this is nothing to worry about. If you're already struggling with the course, then a Java book that you read in parallel to this course could be very helpful. I read several myself and without that knowledge I would not know how I'd solve many of the tasks (and the first 20 levels weren't a big problem for me as I'm not new to coding). I consider the difficulty of some levels to be really high. So learn and ask questions, read as much as you can and see the tasks here as coding practice. Even if they are not always the best and even if the validator is sometimes annoying that practice is what makes you a coder (and of course the ability to look for the solution to your problems yourself). Hey yeah... what do I write here... that's not my style I'm driving nuts, mad, crazy, crazy.... ahhhhh 🤪😜

If you prefer a different way of learning, then this might not be the right website for you. But no one is stopping you from letting the admins know of your preference. Maybe the system will be changed for you.

maybe they must write in rigth solution with the knowledge that they gave their students in the lessons. and not be lazy and write a solution that even looking at you do not understand, since the arrays have not yet passed. they were too lazy to write a solution given our knowledge. and cheated by reducing it to an array. honestly. i wrote a solution and it worked. I was very curious to find out the correct answer, when I looked at the correct answer, I did not understand it, it was with arrays. maybe your opinion is limited to what you know and examples, but not a real outlook. or the comparison may not be correct. I'm sure I honestly demand that they write down the answer not in arrays, they will be later, I know I’m already solving them, but I did not understand that problem because of them. Responsibility needs to be them and tell them so. Ps. In general, I like you, I think you are an experienced programmer. but I am not and I am just learning and I need to explain on my fingers and not skipping over a topic that will only be taught in the future. because the creator of the correct answer to that problem was too lazy to write and wrote the answer at the pro level. not understandable to a beginner. something like that. let's vote!
