Getters and Setters

I am trying to store user input into a set method to be used to compute something in another method within that same class. Having trouble getting it to work though. Here is a bit of whatI have, specifically.

publicdouble price;

publicdouble getPrice()

{

return price;

}

publicvoid setPrice(double p)

{

this.price = p;

}

and in the test...

String input = JOptionPane.showInputDialog ("Unit price");

Double price1 = setPrice(input);

It can return a value, or change to set and then get.Kaj

Two things:1. Like someone has mentioned above. setPrice() doesn't return a value, therefore you cant set the value of 'price1' with it.2. Why do you need public visibility for 'price' attribute?Regards,yc

public class Item {

private double price;

public double getPrice() {

return price;

}

public void setPrice(double price ) {

this.price = price ;

}

...

}

//elsewhere

String input = JOptionPane.showInputDialog ("Unit price");

double unitPrice = Double.parseDouble(input);

Item item = new Item();

item.setPrice(unitPrice);

Does that make sense?
