showInputDialog returns a string, not a double...

another question:

/* Converts seconds into minutes, hours, days */

import javax.swing.*;
import java.text.*;

public class SecondsConvert {

    public static void main (String [] args) {

        String secondsStr;
        int seconds, minutes, hours;
        System.out.println( "This program converts a total number of seconds ");
	System.out.println( "into the equivalent minutes and seconds. ");

	secondsStr = JOptionPane.showInputDialog(null, "Enter the seconds: ");
	seconds = Integer.parseInt(secondsStr);
	minutes = seconds / 60;
	seconds = seconds % 60;
	    
	System.out.println();
	System.out.println(seconds + " seconds = " );
	System.out.println( minutes + " minutes, and " + 
	                    seconds + " seconds. ");
    }
}


// 1. For which range of input values does the existing program work as expected?

so whats the question? the one in comments?

sounds like a homework question to me...

9/13/2005 11:10:51 AM

Well it's a lab and the teacher isn't here, so I have no way of contacting him and we don't have a TA.

anyway

Yeah ignore that comment. The question is how can I correct incorrect ranges, which im assuming a incorrect range is a decimal # because the program errors up. I tried using the DecimalFormat to ("0") but that only likes doubles.

I don't need an answer, just a direction to be looking in and i'll figure it out.

well, I think the only hint I can give you is to look at the variable type... is a number with a decimal an integer?
