Hello everyone,
this is the first time i join any forums and this one looks great

I was just wondering, is it possible to post a problem in simple english that needs programming, so i could learn from that? (i mean is it possible to have that programmed in java, and explained.. so that could help me understand how to take a problem question asked, and solve it in pragramming language)

(Hope that makes sense

) Thank you

welcome... i'm sure anyone here would help you... but you may want to make sure its NOT a homework assignment (unless you try it yourself first and show effort).

welcome new member. I would be glad to help you anytime (if I can).
I am also good in math, so if you have anything, just post.

If you just want to look at some code, why not ask someone to post a little of their own, if they don't mind. That way it's obviously not a homework assignment.

So who has some java code they'd like to show off???

OK. I don't know what level you are in Java, so here is a simple aplication that takes an integer as input and returns its square root as output:

(Toggle Plain Text)

/** Test - takes an integer as input and prints
* its square root */

import javax.swing.*;
public class Test
{ public static void main(String[] args)
  { String n = JOptionPane.showInputDialog("Enter an Integer:");
     //this calls the input dialog
     
     int numri = new Integer(n).intValue();
     //this line converts the input to Integer, because JOptionPane returns String no matter what you input

     System.out.println(Math.sqrt(numri));
     // Math.sqrt finds the square root of the given number
  }
}

Hi, well i am in Univerisity.. but the things i would ask aren't for an assignment.. it's kind of late for assignments now.. it's more about what we do in University (the kind of problems they assign us) and it's to help me understand those better, because i have exams in less than 2 weeks!

Infinite Recursion · May 16th, 2005, 4:22 PM

ask away then

HeX · May 16th, 2005, 4:30 PM

mmm... Now i think I understood you. You want us to post some problems and you will try to solve them (write a program) in order to practice for your exams. Am I right? If not, then post some code or a question and see if we can help.
Actually what university are you attending? (just curious)

aggelos · May 16th, 2005, 4:44 PM

hehe.. well not exactly.. actually i was thinking to ask you problems similar from the ones i get from the University i am attending, then if possible for you to complete.. and post it.. then i could see how a problem like this would be solved (that's why i want to ask if you could include in depth explainations)... so in other words in simple english ask you a problem, and then if you could code it in java..
And i am attending University in Southampton, England... (but im not from england)
(and im asking if you could solve them, because i have problem with my syntax.. and for me, i learn better if i can get it explained, and then practice it myself..)
Hope you understand what i mean

Thank you for your time..

HeX · May 16th, 2005, 4:51 PM

Well first, you need to give a try and put some code together, then if you get a problem, you post the code here and we will see if we can help.
These are the rules here.
