BufferedReader r = new BufferedReader(new InputStreamReader(System.in)); String s1= r.readLine(); int a = Integer.parseInt(s1); String s2 = r.readLine(); int b = Integer.parseInt(s2); String s3= r.readLine(); int c = Integer.parseInt(s3); int arr[] = { a, b,c}; for(int i = 0 ; i < 3 ; i++) { int k = i; for(int j = i+1 ; j < 3 ; j++ ) { if(arr[k] < arr[j]) // swap ( arr[k] , arr[j]); { int temp = arr[k]; arr[k] = arr[j]; arr[j] = temp; } } } for(int n= 0; n < 3; n++) { System.out.println(arr[n] + " "); }

play with input numbers, that's how you will spot the bug.

I know its challenging buddy, so try this: if(a >= b && a >= c) if(b >= c) System.out.println(a+" "+b+" "+c); else System.out.println(a+" "+c+" "+b); else if(b >= a && b >= c) if(a >= c) System.out.println(b+" "+a+" "+c); else System.out.println(b+" "+c+" "+a); else if(c >= a && c >= a) if(a >= b) System.out.println(c+" "+a+" "+b); else System.out.println(c+" "+b+" "+a); Hope i helped :>

I believe this is a system error. I also got an error for the last requirement even though my code worked properly. However, when I refreshed the page for that lesson it said the task was completed.

Better to learn the different methods to sort the collections.

import java.util.ArrayList;
import java.util.Collections;

List<Integer> list = new ArrayList<Integer>();
list.add(num1);
list.add(num2);
list.add(num3);
Collections.sort(list);
System.out.println(list.get(2) + " " + list.get(1) + " " + list.get(0));

use shortcircuit operators. that will be easy
