Thread: Help me plss! :(

here's my code

import java.io.*;
class AllOddNum1
{
 public static void main(String args[])
 {
  try{
 BufferedReader input=new BufferedReader(new InputStreamReader(System.in));
 System.out.println("Enter 20 numbers!!"); 
 int num=1;
 while(num<=20)
 {
 num=Integer.parseInt(input.readLine());
 num++;
 }
 if(num%2!=0)
 { 
 System.out.println(num);
 }
 num++;
 }
 catch(Exception e){}
 }
}

i need to enter 20 numbers then the odd numbers that i enter will display in the output but my program cant display it. help me..

Odd numbers is:11,5,7,9,3

help me

"pls" is not a word in the English language.

When posting code, use the CODE tags to preserve formatting.

Honestly, I'm not even sure where to start with that code. Why do you only loop 5 times? Why are you only keeping track of one number, then incrementing it, then overwriting it without doing anything with it? Why is your logic for determining whether a number is odd outside of the loop? Why do you increment the variable again if it's even? Why do you have an empty catch block?

Wow. For at least the third time today:

Spoonfeeding. Is. Not. Helping.

I am not quite sure about whether you want to display the odd number as soon as it's entered.

What I got is, you are going to enter 10 numbers first constantly. And then once the number feeding is done, you need to display the odd numbers out of the numbers entered.

If thats the case, then store all the numbers in some list for e.g. ArrayList base on your modulus criteria. And then iterate through the list and display the numbers which are odd.

Hope that helps,

Hello FutureExpert.

Welcome to the Java Programming Forums.

I like the username, it's always good to be optimistic!

As Kevin says, there are flaws in your logic but you are getting there.
Following goldest's posts, I have expanded on your code for you. The numbers entered are now stored in an array.

Spoonfeeding is not always the best option but seeing as you are new and I'm in a good mood, hopefully this example will help you to understand what you are missing.
