Making dialogs

[Camya]

I'm trying to write a program that asks the user two numbers - the 1st number is the income, the 2nd is the tax class (either 1 or 2).

If the tax class is 1, the program will divide the income by 10, if the tax class is 2, it will divide by 15. So if a user puts in "8000" as his income and "2" as his tax class, there will be a plain message saying "You're paying 4000 in taxes" (taxes=8000/15).

I have no idea how to even start on this. I'm able to write a simple program that asks a user to type in his name, then shows a "Hello <NAME>!" message... but not this. Can someone please help me, give me a push in the right direction? It would be so much appreciated.

this is what I've got so far - I can't even get the if/else thing to work. I've only done this for a couple of weeks >.<

You're almost there (the input part that is): that JOptionPane can get a String
from the user; you can convert that String to a number (if it is a representation
of a number); read the API documentation for the Integer or Double classes.
They implement methods that can convert appropriate Strings to ints or doubles.

kind regards,

Below is the code, but I dont understand how 8000/15 equals 4000. Anyway check the code below

No problem and no hard feelings; just don't post boilerplate code; it really doesn't
help the OPs; most of them just copy and paste it and even turn it in as if it were
their own code. There's too much trash in the IT world already (you wouldn't
want a cheater as a colleague?). This is all not implying that the current OP
would be cheating. And it also doesn't imply that your contributions are not
appreciated; keep up the good work.

kind regards,

Hey hi bro nice code but i wanna u to work a few:
Use J2SE 6(SDK i meant)
Here i just show u how u can use ur Interger or double
I get ur string as u use s but after da convert into int or double wid nextInt or nextDouble,rewrite ur prog after reding mine good luck see ya soon

Please mind your spelling, please don't post spoonfeeding code and most
important: please read the forum posting guidelines (select the 'Help' link

Thanks you so much for the help - it took me a while, but I finally figured it out ^^ Aahh... it feels good :D

or... I think I did. It works at least, but I don't know if I did it "right".

public class task4 {
 
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        double tax;
        double income;
        int taxclass;
 
        String s=javax.swing.JOptionPane.showInputDialog("Your income is:");
        String t=javax.swing.JOptionPane.showInputDialog("Your tax class is:");
 
        tax class = Integer.parseInt(t);
        income = Double.parseDouble(s);
 
        if(taxclass ==1){
            tax=income/10;
        }
        else {
            tax=income/15;
        }
 
        String tittel=("Tax");
        String info= "Taxes are "+tax;
        javax.swing.JOptionPane.showMessageDialog(null, info, tittel, javax.swing.JOptionPane.PLAIN_MESSAGE);
 
    }
 
}

I've got another question.

Wasn't sure whether I'm supposed to make a new thread....? Anyhow, my next task is

"Make a program that asks the user for a text, prints out the number of characters in the text, splits the text in half and switch the parts and returns the result to the user".

Meaning abcdefgh should come out as "efghabcd".

Um. I think I can figure it out, sooner or later, except for the part about splitting the text. Not asking anyone to spoonfeed me code, but a little hint on this area would be great :)

You should probably start a new thread for it but I don't think it will be a long thread anyway. You want to have a look at the String.susbstring method. Open the API docs for the String class. You'll find some more usefull methods there.
