This is my very first java program
I made this program that can tell how many euro danish crowns is

1 Euro = 7,45 Danish Crowns

Put amount to exchange


Amount was 7,45 Danish crowns

Code: Select all

import javax.swing.JOptionPane;

public class Valuta {

	
	public static void main(String[] args) {
		
		double vul, val, sum;
		String str1 = JOptionPane.showInputDialog("Indtast et tal du vil omregne til euro");
	 	str1 = str1.replaceAll(",", ".");
       	       
	 	vul = 7.45;
	 	 val = Double.valueOf(str1.trim()).doubleValue();
			
				sum = val / vul;

System.out.println(val + "Dkk omregnet til Euro = " +  sum + "Euro");
		JOptionPane.showMessageDialog(null, str1 + " Dkk er = " + sum + " euro", "Dkk til Euro ", JOptionPane.INFORMATION_MESSAGE);
	}

}

cool
but do you have to always add the converted value in the code itself?
seems it gonna be a LONG project then :lol:

No i dont add the converted value

sum = val / vul
vul is always 7,45 and val is your input
50 / 7,45 = 6,71 Euro
7,45 / 7,45 = 1 Euro
