i tryed something like 7 - 9 hours to solve this problem i the end i watch coorect solution

Question about the task

Under discussion

why there arrays ?! why?! we are not learned arrays. my experience and knowledge only what we learn and study before this task. based on previous information. wtf. the founders wrote it like this. the fact that everyone finds the right answer in the community and says and writes from one person to another what they themselves or someone else saw in the correct answer for a long time and write it off is some kind of nonsense. there is even no mention of arrays in the assignments. I would read it in a book. 9 hours I wrote a whole book in volume I wrote everything I tried I had a bunch of questions that do not even understand. I found this while trying all the options. even that the methods and cycles of ari in different circumstances work in different ways right in the details only noticeably. generally differently. I think this task is just some kind of mockery of the students. - 5 stars for this task. i dont sleep half of night and start from middle of day tryed solve this task . jerks!!

Write a program that:
1. reads a number N (must be greater than 0) from the console
2. reads N numbers from the console
3. Displays the maximum of the N entered numbers.

Requirements:

The program should read the numbers from the keyboard.
The program must display a number on the screen.
The class must have a public static void main method.
Don't add new methods to the Solution class.
The program should display the maximum of the N entered numbers.
The program should not display anything if N is less than or equal to 0.

package com.codegym.task.task05.task0532; import java.io.*; /* Task about algorithms */ public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int maximum = ; //write your code here System.out.println(maximum); } }

Somewhere at the beginning of the course, it was explained that there would be some tasks that were very difficult. And even some we didn't study about before. And this thing is intentional. It's to brace up students for real life, real world programming. They say real programming is like this: from time to time you're confronted with problems you didn't learn about, but you must be forced to figure out. But it is also an option to leave such too difficult tasks unresolved first, and return to them later when you have learned more. But you can also learn from the downloaded correct solution. One of your published solutions was near to the right one (as I wrote earlier). It worked with positive integers correctly! And you didn't use an array. (I didn't use an array when I solved this either.)

This task is simple and does not require arrays. The "solution" provided by codegym is only one variation of a passable solution. To pass this task only requires that the steps be followed. If you don't follow the 3 steps then it wont pass. Step 1: Reads a number greater than 0, called N Step 2: Use the number read from step 1, N, and reads N numbers. So if the user enters 6 for step 1 then this step should read 6 numbers. If the user enters 15 for step 1 then this step should read 15 numbers. Step 3: Of the numbers from step 2 output the maximum. So if the user enters 6 for step 1, then enters (6 numbers) -5, 3, 5, -2, 1, -1 for step 2, then the correct output would be 5 since that it the max number of those 6. If the user enters 3 for step 1, then enters -1, -2, -3 for step 2, then the correct output would be -1 as that is the max of the 3 numbers from step 2.

just for you... no arrays involved

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
int     n = Integer.parseInt(reader.readLine()); // N has to be > 0
int     number, // temp variable that holds the input
        maximum = Integer.parseInt(reader.readLine()); // maximum, holds the max and already the first input (N > 0 -> np)

for (int i = 1; i < n; i++) {
    number = Integer.parseInt(reader.readLine());
    maximum = Math.max(maximum, number);
}

System.out.println(maximum);

that's the code I validated. No arrays but a list (I wanted to validate (if possible) using streams...)

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

int n = Integer.parseInt(reader.readLine());
if (n > 0) {
    List<Integer> nums = new ArrayList<>();
    for (int i = 0; i < n; i++)
        nums.add(Integer.parseInt(reader.readLine()));
    System.out.println(nums.stream()
            .mapToInt(Integer::valueOf)
            .max()
            .getAsInt()
    );
}
