Integer troubles

[Tb0h]

I am constructing a program in which you enter eight numbers. At the end it will display the sum of these numbers. But when I run the code, it simply displays the numbers side by side each other. My IDE is eclipse.
Here is the code:

import javax.swing.JOptionPane;

public class Main {

	public static void main(String[] args)
	{
		String a;
		a = JOptionPane.showInputDialog
				("Welcome to the Averaging Machine Basic! Enter your first number.");
		String b;
		b = JOptionPane.showInputDialog
				("Enter your second number.");
		String c;
		c = JOptionPane.showInputDialog
				("Enter your third number.");
		String d;
		d = JOptionPane.showInputDialog
				("Enter your fourth number.");
		String e;
		e = JOptionPane.showInputDialog
				("Enter your fifth number.");
		String f;
		f = JOptionPane.showInputDialog
				("Enter your sixth number.");
		String g;
		g = JOptionPane.showInputDialog
				("Enter your seventh number.");
		String h;
		h = JOptionPane.showInputDialog
				("Enter your eighth number.");
		int a1 = Integer.parseInt(a);
		int b1 = Integer.parseInt(b);
		int c1 = Integer.parseInt(c);
		int d1 = Integer.parseInt(d);
		int e1 = Integer.parseInt(e);
		int f1 = Integer.parseInt(f);
		int g1 = Integer.parseInt(g);
		int h1 = Integer.parseInt(h);
		JOptionPane.showMessageDialog(null,"The average of " + a + "," + b + "," + c + "," + d + "," + e + "," + f + "," + g + " and " + h + " is "  + a + b + c + d + e + f + g,"Output",JOptionPane.INFORMATION_MESSAGE);
	}
}

when you stick in + signs where a string is expected, it concatenates the strings with one another. you probably already knew that, though.

Also, you said average where it should say 'sum'. Just saying. make another variable called sum (an integer) and make that equal what you said at the end.

[Tb0h]

Yes; I originally intended this to be an averaging program. But before I do that, I want to figure out how to add integers. Also, yes I knew, emceenugget.

[Tb0h]

So how DO you add multiple integers?

[coffee]

sum = int1+int2+int3;
EDIT:
Here, I wrote up a little tut for you:

import java.util.Scanner;
public class test {
	public static void main(String[] args) {
		Scanner s = new Scanner(System.in); //get input from user
		System.out.print("Please enter the integers to average seperated by a space: "); //ask for integers
		String[] all = (s.nextLine().split(" ")); //get the individual numbers in string format
		int total = 0; //initiate our variable for the total
		for (int i=0; i<all.length; ++i) { //loop through the array's values
			total += Integer.parseInt(all[i]); //parse the string into an integer and add that to total
		}
		total /= all.length-1; //divide by amount of integers in array
		System.out.println("Average: "+total);
	}
}

This is great, thanks :)
But still, I want to learn how to fix what I've done wrong with my code.

Simply enough, instead of adding the integers, you added the string equivalents of the integers. Just create a variable for the total, and add them there. Then, add the total to the string printed on the screen, instead of all those variables. :)

u add all the values in a newly cerate variable int
and display that variable

[coffee]

Yup. Thats how you do it.

[Tb0h]

Ah, knew it was something like that. Thank you, coffee and britto bicsjohn.

No problem! :)
