hi, can anyone help me with my codes. I can't find the right solution for getting the average of the sum. For example, my first number is 1 and the second is 10. It will get the sum of either all the even nos there or the odd nos there. And then it will get the average of it. Pls help me. tnx.

it's a bit messy

hi, we have a simple program here that states like this:

input >= 10

ex: 12

1	Square		Sqrt		Cube		Fouthroot
2	-		-		-		-	
3	-		-		-		-
4
5
6
7
8
9
10
11
12

i made the code already but I still can't find a solution the solutions from 1 to 11.. my code only displays the results for the 12... I know this can be solved pretty easily by some loops, but for a strange reason,I can't find the right algorithm! lol! i just need an algorithm and just leave the programming to me..tnx

I promise this will be my last question..lol..
how can I change the path in the control panel?

yup..I downloaded the link you provided..
actually I have Java(TM) 6 Update 10
& Java(TM) 6 Update 7

what else should I download?
I downloaded already a NetBeans Installer

yeah...I didn't noticed there were many typographical errors..lol..so.. it would be like this:

h = input.nextDouble();

and also which one should I download? I tried many updates now but NetBeans still seerches for a full JDK..that's why I can't proceed..I downloaded (netbeans-6.1-ml-javase-windows)..is this enough?will this work if I downloaded the right JDK?

hi we have a programming assignment which computes the volume of a barrel. I don't have a compiler yet and java is not yet recognized by my computer yet because I haven't downloaded any JDK yet because I don't know which one to download...Here's my code so far...Please just review my codes because I can't test them and this is my first programming ass in java..so i'm still a newbie..

import java.util.Scanner;

public class A1{
	public static void main(String args[])
	{
	double h, r1, r2; byte b;
	
	Sanner input = new Scanner(System.in);
	System.out.println("Enter r1 & r2");
	b = input.nextByte();
	r1 = input.nextDouble();
	r2 = input.nextDouble();

	System.out.print("Volume Of the barrel is= "
	+ (h*Math.Pi*(((2*r1)*(2*r1)) + ((r2)*(r2))) / 3));
	}
}

you're hopeless...show some effort before posting threads here

hmmm..im almost there!!tnx!! do you know how to read & write???

yah...that's what my problem is...I cant send & receive...how can I?

hi, my problem is about socket programming. My code below only connects the client to the server, and it works just fine. However, I should create a 2player game which of course require the interaction of the 1st and 2nd player. The problem here is that they really don't interact with each other, it is as if the terminal for the client side is a separate program from the terminal for the server side(sorry if I can't explain it clearly..lol) yeah, the client connected successfully, but they don't interact..pls I really need this code or else I'll fail my subject..tnx a lot!

but we haven't discussed it yet those..I don't have any idea.. and I think it's already an advanced programming... so my professor will understand my situation. Anyway, I revised the game and it still looks fine even without the timer...

so it can be done using multithreading...and i don't even have any idea how to do one! lol...maybe i'll just scrap the timer idea on the game..but tnx anyways for your response

Is it posibble to have a count-down timer while I'm doing something else in the console? it's a simple game wherein a specified time is allowed for the player..if possible, how? I created a timer but it waits until it finishes before proceding to the game..tnx in advance

hi, im creating a simple game here...its a shooting game...so how can I make my program read the keyboard to control the player's movement around?tnx in advance

can anyone recommend me a website with a sample of socket which can help me create a 2-player game in c++, or much better, a game using socket?tnx

websites is not really my specialty...so how can I connect modules? and also how can a user update, lets say his bulletin, by just editing it just like in multiply...any suggestions or online tutorials will be appreciated ..tnx

Can anyone suggest a good website that can teach me Oracle? thanks in advance..

our group made a decision to do a dynamic website, and the best tool for this is PHP! But this is too risky...why? because none of us has any background on it!!! can anyone recommend a site that can teach me how to use PHP...any help would be appreciated..tnx

guys, i have a project to do this school year, and that is a dynamic website..the problem is that i don't have a good background with dhtml so can anyone recommend me a website that can teach me how???tnx

simply create an option for the user to choose...lets say switch case is the best way

i'm new to c++....i'm making a project here but i have a problem with this: reading values as type char and converting it to type int...such that 54 can be read as '5' and '4' but after that it will be read into type int...can anyone please tell me how?
