Under discussion

Help would be appreciated..:(

package com.codegym.task.task04.task0420; /* Sorting three numbers */ import java.io.*; public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String a = reader.readLine(); String b = reader.readLine(); String c = reader.readLine(); int e = Integer.parseInt(a); int f = Integer.parseInt(b); int g = Integer.parseInt(c); if (e > f) if (f > g) System.out.println(e + " " + f + " " + g); else System.out.println(e + " " + g + " " + f); else if (f > e) if (e > g) System.out.println(f + " " + e + " " + g); else System.out.println(f + " " + g + " " + e); else if (g > e) if (e > f) System.out.println(g + " " + e + " " + f); else System.out.println(g + " " + f + " " + e); } }

you have to account for the = sign if two numbers out of the 3 are the same.

* First find the numbers of both ends(greatest and least). * Then add them together. * Then minus the result from addition of all three number. * The result would be the middle number. [Hint: Make two different methods for the greatest and the least number.]

I have not changed anything about your code, just added some sys.out statements for output so that you can see what your code is doing. Copy and paste this to replace lines 19-33.

if (e > f) {
            System.out.println("First statement true: " + e + " is greater than " + f);
            System.out.println("Checking if " + f + " is greater than " + g +"? " + (f > g));
            if (f > g)
                System.out.println(e + " " + f + " " + g);
            else
                System.out.println(e + " " + g + " " + f);
        }
        else if (f > e) {
            System.out.println("Second statement true: " + f + " is greater than " + e);
            System.out.println("Checking if " + f + " is greater than " + g +"? " + (e > g));
            if (e > g)
                System.out.println(f + " " + e + " " + g);
            else
                System.out.println(f + " " + g + " " + e);
        }
        else if (g > e) {
            System.out.println("Second statement true: " + g + " is greater than " + e);
            System.out.println("Checking if " + f + " is greater than " + g +"? " + (e > f));
            if (e > f)
                System.out.println(g + " " + e + " " + f);
            else
                System.out.println(g + " " + f + " " + e);
        }

Run this with some test values

public class Solution { public static void main(String[] args) throws Exception { //write your code here BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); int x=Integer.parseInt(br.readLine()); BufferedReader br1 = new BufferedReader(new InputStreamReader(System.in)); int y=Integer.parseInt(br1.readLine()); BufferedReader br2 = new BufferedReader(new InputStreamReader(System.in)); int z=Integer.parseInt(br2.readLine()); if(x>=y && x>=z){ if(y>=z) { System.out.println(x+ " " + y + " "+ z); } else { System.out.println(x+ " " + z + " "+ y); } }else if(y>=x && y>=z) { if(x>=z) { System.out.println(y+ " " + x + " "+ z); } else { System.out.println(y+ " " + z + " "+ x); } }else if(z>=x && z>=y) { if(x>=y) { System.out.println(z+ " " + x + " "+ y); } else { System.out.println(z+ " " + y + " "+ x); } } } } by using the above code I got the correct output.
