Question about the task Creating a two-dimensional array
Java Syntax, Level 5, Lesson 5
Resolved
Not sure about the input type and if condition Hey guys, do you know why the input is in String, instead of int? 1) Does it need to be a String here (or could the provide an int, too), or why did Codegym give us Strings instead of ints as input? 2) Is it bad practice to use an if, to check if the number is positive here? 2.1) Why don't we need

My solution considered correct and it's solved now, but I don't think so. public class Solution { public static int[][] multiArray; public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int input = scanner.nextInt(); if (input > 0) { int times = input; multiArray = new int[input][];

Why do we use an "initialize method" instead of a constructor. Why do we use an "initialize method" instead of a constructor? At face value, it looks like they both do the same thing.

Question about the task Aggregator (part 5)
Java Collections, Level 8, Lesson 15
New
