* 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.

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); } } } } check this code.I got the correct output by trying in this way.

your last nested-if statement is a duplicate of the if-statement.

you can solve it very easily with Arrays.sort() method. 1. first declare a int array of size 3. 3. store accepted input in that array. 4. use Arrays.sort(INPUT ARRAY) 5. and now traverse that array in reverse order and you got your output :)

use else if in line 26 and 33 instead of if only. moreover your if conditions are partially correct. make them correct and you will get the result.

You have to sort three numbers in descending order. Your sorting logic is not correct. Try your program with the below input -

3
2
1

It will not produce the desired result. Then check why it is failing and then rectify the mistake.
