iight so im in this computer science class and we have to write a program that tells the user to input 5 intergers seperated by a space, read and the store the integers, and find the average of them. this is what i have so far...


/* This program ask the user for his name and 5 test scores and computes the average
*
*By Lionso
*/

import javax.swing.JOptionPane;
import java.util.Scanner;
public class scorefive {
public static void main(String [] args) {
//declare variables
int score1;
int score2;
int score3;
int score4;
int score5;
double average;
Scanner input;


//prompt user for input and save it
JOptionPane.showInputDialog(null, "Please input 5 integers seperated by a space");
input = new Scanner(System.in);
score1 = input.nextInt();
score2 = input.nextInt();
score3 = input.nextInt();
score4 = input.nextInt();
score5 = input.nextInt();

//compute average
average = (score1+score2+score3+score4+score5)/5.0;

//display average
JOptionPane.showMessageDialog(null,"Your average is"+ " "+ average);

}
}


now when i run the program, the joptionpane input dialog pops up and asks for the integers. now the problem that i am having is having the program store the input. teacher sucks at helping. he just ask's you another question on top of your question. thanks for any1 who helps me out on this one.

 

Not familiar with Java, but try outputting the numbers right after they get stored to a message box. What is in there when you do that?

 

well when i do it, the program is trying to find the numbers being stored. everything is right except that i cant seem to store the the integers being inputed into the dialog box.

 

im not familair with java either but it looks to me like your not setting a variable name for the integer.

 

Are you forced to use Java? Iostream.h would work better in this situation if you are using simple DOS input.
And that cannot be your entire code, can it? As I am not familiar with Java, should there not be a start? Like:
main()
{
blah blah
blah bah, your junk here
}

 

^ I'm with that...cin>>num1; cin>>num2; etc...

 

cin cout for the win.
With all things code - go simple. The more complex you try, the more you F up. I use to always forget the ";". Hard to see the difference in : and ; when you have a large code.

 

I used to confuse the effects of && and ||

 

lol. God we are nerds.
What sucks is when you confuse it, and the prog. wont run. You go back and read the code and NOT realize your error. Can take hours for you to realize your : should be a ;, or your && should be ||. annoying stuff.

I'm actually very surprised other memebers know C++ and other programming languages.

 

i actually did this exact program for my CS class...well we had to ask how many numbers should be avg'd
