I think my output is correct...

Question about the task

Three numbers

Java Syntax, Level 3, Lesson 5

Resolved

Then why is it saying

Use the keyboard to enter three integers. Determine whether there is at least one pair of equal numbers among them.
If such a pair exists, display the numbers separated by spaces. If all three numbers are equal, then display all three.

Examples:
a) if we enter the numbers 1 2 2, then the output we get is 2 2

b) if we enter the numbers 2 2 2, then the output we get is 2 2 2

Requirements:

The program should read three number from the keyboard.
The program must contain System.out.println() or System.out.print().
If two numbers are equal, you need to display them on the screen.
If all three numbers are equal, you need to display all three.
If none of the numbers are equal, then display nothing.

package en.codegym.task.pro.task03.task0305; import java.util.Scanner; /* Three numbers */ public class Solution { public static void main(String[] args) { //write your code here Scanner sc = new Scanner(System.in); int a = sc.nextInt(); int b =sc.nextInt(); int c =sc.nextInt(); if(a==b){ System.out.print(a+""+b); if(b==c) System.out.println(c); } else if( b==c){ System.out.print(b+""+c); if(a==c) System.out.println(a); } else if(a==c) System.out.print(a+""+c); if(b==a) System.out.println(b); } }

have a look at your last else if and add parentheses after it like you did in the staring if and the else if before (closing it between line 29 and 30) my approach was

// a print or println needs to be in the code otherwise it won't validate. That's why String.format inside
// println is used once
if (a == b && a == c) {
    System.out.println(String.format("%1$d %1$d %1$d", a));
} else if (a == b || a == c ) {
    System.out.format("%1$d %1$d%n", a);
} else if (b == c) {
    System.out.format("%1$d %1$d%n", b);
}

eg. 1 1 2 does not give the correct output 1 1 but 11 1 Neither does 1 1 1. The output is 111 1 while it should be 1 1 1 numbers also separated by a space (at least I think so)
