Thread: Can someone help me out with this

Hey guys so I made this code for wind chill temp and Im stuck on one part.
the part Im stuck on is that he wants a programs with dialog boxs and restriction

"temp ranges -58 - 41 and wind speed greater than or equal to 2. He wants us to have in there that if the user types in an invalid number for both parts a box will pop up and say error.
I have tried if and else statemnts but i get red line so can someone look over it and help me modify it please

import javax.swing.JOptionPane;
 
public class Temperature {
 
    public static void main(String[] args) {
 
        String Temp = JOptionPane.showInputDialog("Enter outside Temperature in Farhrenheit. Temp should be between -58F and 41F");
        double Temperature = Double.parseDouble(Temp);
 
        String Wind = JOptionPane.showInputDialog("What is the MPH of the wind ex: q.2.3.4.5.6 ect.");
        double WindSpeed = Double.parseDouble(Wind);
 
        double Chill = 35.74 + (0.6215 * Temperature) + (35.75 * (Math.pow(WindSpeed, 0.16))) + (0.4275 * (Temperature * (Math.pow(WindSpeed, 0.16))));
 
        Chill = (int) (Chill * 100 / 100.0);
 
        System.out.println("The Wind-Chill Temperature is:" + Chill);
 
    }//end of main method
 
}

Please edit your post and wrap your code with code tags:

I need to add...

What problems are you having with that? Do you have any specific questions about what to do?

Use an if statement to test for the bad value:
if (bad data) {
show a message
}
