По условие не се изисква сортиране на елементите - премахнете го (редове 48-58).

Премахнете символа за нов ред (%n) от toString метода (ред 26).

Останалите методи на Article класа не са необходими, но и не пречат на решението да мине в Judge:

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Articles {
    private String title;
    private String content;
    private String author;

    public Articles (String title, String content, String author) {
        this.title = title;
        this.content = content;
        this.author = author;
    }

    @Override
    public String toString() {
        return String.format("%s - %s: %s", this.title, this.content, this.author);
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        List<Articles> articleList = new ArrayList<>();
        int n = Integer.parseInt(scanner.nextLine());

        for (int i = 1; i <= n; i++) {
            String article = scanner.nextLine();
            String[] parts = article.split(", ");
            String title = parts[0];
            String content = parts[1];
            String author = parts[2];

            Articles currentArticle = new Articles(title, content, author);
            articleList.add(currentArticle);
        }

        String command = scanner.nextLine();

        for (Articles current : articleList) {
            String result = current.toString();
            System.out.println(result);
        }
    }
}
