Giving a Label a number

[Steven Joost]

Hello guys, I have a question, how can a JLabel get a number?

For example:

import java.awt.*;
import javax.swing.*;

public class First{

double Ax = 0.0, Ay = 0.0;

JLabel label = new JLabel();

public static void main(String[] args){

label.setText(Math.sin(Ax+Ay));

}

}

Sorry for my bad English, I'm german ;)

is there anything what I can use instead of .setText?

Format the number as a String using java.text.DecimalFormat and then use setText() .

Welcome to the Ranch

I would probably use String#format() myself, in preference to Decimal Format.

Or you could simply concatenate the number to an empty string
