Task is comply and work but one Requirements did not pass...

Question about the task

Under discussion

Failed task --> The program should display the numbers in descending order. But it is working as it should, tried it with the couple of numbers..

package com.codegym.task.task04.task0420; /* Sorting three numbers */ import java.io.*; import java.util.*; public class Solution { public static void main(String[] args) throws Exception { Scanner scanner = new Scanner(System.in); int a = scanner.nextInt(); int b = scanner.nextInt(); int c = scanner.nextInt(); int d; int e; int f; if (a<b && a<c && b<c){ d = a; e = b; f = c; System.out.println(f +" "+ e +" "+ d); } else if (b<a && b<c && a<c){ d = b; e = a; f = c; System.out.println(f +" "+ e +" "+ d); } else if (c<b && c<a && b<a){ d = c; e = b; f = a; System.out.println(f +" "+ e +" "+ d); } } }

check your code with input like a=b=c (or) a= 2 b=2 c=4.nothing will print. I think you understood where your mistake is

#1 : If the above code is the one that you ran it won't print anything because for the input 2 2 4 there isn't any condition in your code that checks whether two numbers are equal.for this input it cannot pass any if statements so nothing will print. #2 : since there are 3 numbers there are 3! = 3*2 = 6 ways of writing them in descending order but you are implementing only 3 of them try like this

if (a>=b&&b>=c)
      System.out.println(a+" "+ b+" "+c);
 else if (a>=c&&c>=b)
      System.out.println(a+" "+ c+" "+b);
 else if (b>=a&&a>=c)
      System.out.println(b+" "+ a+" "+c);
 else if (b>=c&&c>=a)
     System.out.println(b+" "+ c+" "+a);
else if (c>=b&&b>=a)
     System.out.println(c+" "+ b+" "+a);
  else if (c>=a&&a>=b)
     System.out.println(c+" "+ a+" "+b);
