The program cover this case !

Question about the task

Resolved

Hello EveryOne The checker is still rejecting my program (file attached) when it really cover this case. The reject reason : If several second smallest numbers are entered, then you need to display any one of them. Thanks for your help.

package en.codegym.task.pro.task04.task0410;

import java.util.Scanner;

/*
Second smallest number entered
*/

public class Solution {
    public static void main(String[] args) {
        //write your code here
        Scanner console = new Scanner(System.in);
        int integer = 0, fstMin = Integer.MAX_VALUE,
            secMin = Integer.MAX_VALUE, nbrInt = 0;
        while(true)
           {   if (console.hasNextInt())
                  {
                    integer = console.nextInt();
                    if (fstMin == Integer.MAX_VALUE)
                       fstMin = secMin = integer;
                    else
                       {
                          if (fstMin == secMin)
                              {
                                  if (fstMin > integer)
                                     fstMin = integer;
                                  else
                                     secMin = integer;
                              }
                          else
                               {
                                   if (fstMin > integer)
                                      {
                                       secMin = fstMin;
                                       fstMin = integer;
                                      }

                                   else if (secMin > integer)
                                          secMin = integer;
                               }

                       }
                  }
               else
                  break;
               nbrInt++;
           }
        if (nbrInt < 2)
           System.exit(-1);
        else
           System.out.println(secMin);

    }
}

In this task, you need to:

Read integers from the keyboard until something else is entered, such as a string or a character.
At least two numbers must be entered. If less than two integers are entered, then terminate the program with an error. You don't need to handle this situation.
Display the second smallest integer entered from the keyboard. If several such numbers are entered, you must display any of them.
There may also be several minimum numbers.

Example input:

8

4 // Minimum number

7

4 // Minimum number

5 // Second smallest number

9

5 // Second smallest number

exit

Example output:
5

Requirements:

The program should read numbers from the keyboard.
The program should display a number on the screen.
The program should display the second smallest integer entered.
If several second smallest numbers are entered, then you need to display any one of them.
You need to read data from the keyboard in a while loop.

package en.codegym.task.pro.task04.task0410; import java.util.Scanner; /* Second smallest number entered */ public class Solution { public static void main(String[] args) { //write your code here Scanner console = new Scanner(System.in); int integer = 0, fstMin = Integer.MAX_VALUE, secMin = Integer.MAX_VALUE, nbrInt = 0; while(true) { if (console.hasNextInt()) { integer = console.nextInt(); if (fstMin == Integer.MAX_VALUE) fstMin = secMin = integer; else { if (fstMin == secMin) { if (fstMin > integer) fstMin = integer; else secMin = integer; } else { if (fstMin > integer) { secMin = fstMin; fstMin = integer; } else if (secMin > integer) secMin = integer; } } } else break; nbrInt++; } if (nbrInt < 2) System.exit(-1); else System.out.println(secMin); } }

Maybe try to remove the System.exit() call and instead replace it with a return;

Thanks Lisa, it's a void main function, I can't return anything, I removed the System.exit(-1) but the problem persist (same uncovered requirement).

I changed the last test, Iput : else if (secMin > integer && fstMin < integer) instead of else if (secMin > integer) And it worked, but this has no meaning, because in this case (the else), we have necessarily fstMin < integer. there is a problem in the checker. Thanks again Lisa for your answer.
