Calculate average age for women and men?

[Legoland]

Hi!
I have just started with Java and found this forum before I have been doing a lot of reading here but now I need some help since I´m stuck.
I want to make a program that will calculate the averageage for women and and men one group for women and one for men.At the end the program should say buy buy and then show the averageage for women and men.
The program looks like this.
import javax.swing.*;

public class Person {

public static void main(String [] arg) {

String kvinna;

String man;

String txt= "";

int start= JOptionPane.showConfirmDialog(null,"Välkommen!"+

"\nVill du räkna medelåldern?", "Fråga", JOptionPane.YES_NO_OPTION);

if (start == 0){

for (int i=1 ; i>= 0; i++) {

for(int j=1 ;j <= i; j++){

int knapp= JOptionPane.showConfirmDialog(null,"En kvinna?");

if(knapp == 0) {

kvinna= JOptionPane.showInputDialog("Hur gammal är kvinnan?");

if (false)

break;

else {

int k1= Integer.parseInt(kvinna);

int medel1= k1 / j;

String txt1= txt + medel1;
}
}

else if(knapp == 1) {

man= JOptionPane.showInputDialog("Hur gammal är mannen?");

if (false)

break;

else {

int m1= Integer.parseInt(man);

int medel2= m1 / j;

String txt2= txt +medel2;

}
}

else

break;

} // for1 slut

} // for2 slsut

} // if1 slut

else




JOptionPane.showMessageDialog(null, "Hej då!"); (Hej då is Buy Buy in swedish)

System.exit(0);


//JOptionPane.showMessageDialog(null,"Medelåldern för kvinnor är: " + txt1 + "\nMedelåldern för män är: " + txt2);( this is the calculation for women and men)

//System.exit(0);
} //main slut
} //class slut

Thansk for input and help in advance.

For me it was difficult to understand spanish , Look at the code let me know the status

Code:

package com.test.workarea;

import javax.swing.JOptionPane;

public class Person {

	public static void main(String [] arg) {

		String kvinna;

		String man;

		String txt= "";
		int i=0,j=0;
		int sumk1=0,summ1 =0;

		int start= JOptionPane.showConfirmDialog(null,"Välkommen!"+

				"\nVill du räkna medelåldern?", "Fråga", JOptionPane.YES_NO_OPTION);

		while(start == 0){


					int knapp= JOptionPane.showConfirmDialog(null,"En kvinna?");

					if(knapp == 0) {

						kvinna= JOptionPane.showInputDialog("Hur gammal är kvinnan?");// Assumes this asks men
						
						if(kvinna != null ){

							int k1= Integer.parseInt(kvinna);
							sumk1 = sumk1 + k1;
							i = i +1;
						}
					}

					else if(knapp == 1) {

						man= JOptionPane.showInputDialog("Hur gammal är mannen?"); //Assumes this asks women
						if(man != null){
							int m1= Integer.parseInt(man);
							summ1 = summ1 + m1;
							j = j +1;
						}

					}

					else

						break;


		} // if1 slut

	



			JOptionPane.showMessageDialog(null, "Hej då!");// (Hej då is Buy Buy in swedish)

		

		JOptionPane.showMessageDialog(null,"Medelåldern för kvinnor är: " + sumk1/i + "\nMedelåldern för män är: " + summ1/j);//( this is the calculation for women and men)
