Can someone tell me the reason for this error...???

Question about the task

Resolved

import java.util.Scanner; public class Solution { public static void main(String[] args) throws Exception { Scanner in = new Scanner(System.in); int a = in.nextInt(); int b = in.nextInt(); int c = in.nextInt(); if( a == b){ System.out.println( a+" "+b); } else if( b == c){ System.out.println( c+" "+b); } else if( c == a){ System.out.println( a+" "+c); } else if(( a == b ) && (b == c)){ System.out.println( a+" "+b+" "+c); } } }

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 a space.
If all three numbers are equal, then display all three.

Here are some examples:
a) if you enter the numbers
1
2
2
then we display
2 2

b) if you enter the numbers
2
2
2
then we display
2 2 2

Requirements:

The program should read the numbers from the keyboard.
The program should contain System.out.println() or System.out.print().
If two numbers are equal to each other, you must display them on the screen.
If all three numbers are equal, then display all three.
If there are no equal numbers, don't display anything.

package com.codegym.task.task04.task0417; /* Do we have a pair? */ import java.util.Scanner; public class Solution { public static void main(String[] args) throws Exception { Scanner in = new Scanner(System.in); int a = in.nextInt(); int b = in.nextInt(); int c = in.nextInt(); if( a == b){ System.out.println( a+" "+b); } else if( b == c){ System.out.println( c+" "+b); } else if( c == a){ System.out.println( a+" "+c); } else if(( a == b ) && (b == c)){ System.out.println( a+" "+b+" "+c); } } }

keep this condition as a first condition. if(( a == b ) && (b == c))

useful

your problem is occurring in the if(a==b) clause,which is executing first a and b variable and its always being true and printing first when three variable are equal and last else if(( a == b ) && (b == c)) clause is not executing cause of someone already executed. i hope u got it! So you have to put the last condition as a first one!

If two numbers are equal to each other, you must display them on the screen. If all three numbers are equal, then display all three. getting these errors

solution

that's why first of all you have to check is all three variables are equal or not? if all of them are equal,ultimately a and b are equal,so a==b condition getting first and executing first.hope u got it! put the last condition as a first one!
