I really don't get what's wrong :Upon verification it says that "The program should display the minimum of two integers." It couldn't be much simpler package com.codegym.task.task04.task0418; /* Minimum of two numbers */ import java.io.*; public class Solution { public static void main(String[] args) throws Exception {

Question about the task Greater than 10? You're not a good fit for us
Java Syntax, Level 8, Lesson 8
Under discussion
createSet() not pass because I used Math.random() to generate 20 random number I tested the code, it showed correct output but when verified, it does not pass the createSet() method condition. I suspect it because Math.random() generate some same number in the list of 20 number like: 10 20 23 46 34 10....89. Here I can have 2 number "10", not satify, 20 different numbers Anyo

How does this make any sense...Literally everything is public and everything should be right and everything is synced. CodeGym drives up the effing wall sometimes. It is such shit at explaining anything clearly especially the requirements for their tasks. I always feel like I am being asked to do things by a two year old that doe

Completely lost This runs with the proper output in IntelliJ but fails to compile when I submit. Failure to compile is because the Statics class is not found. Everything I find online says to import the class explicitly, but it doesn't work.
