import javax.swing.JOptionPane;
public class TimeCalculator
{
public static void main(String [] args)
{
String input;
double seconds, minutesCalculated, hoursCalculated, daysCalculated;
final double secondsPerMinute = 60;
final double secondsPerHour = 3600;
final double secondsPerDay = 86400;
input = JOptionPane.showInputDialog("Enter the seconds:");
seconds = Double.parseDouble(input);
if (seconds < secondsPerMinute)
{
JOptionPane.showMessageDialog(null, seconds + " seconds (no conversion was made)");
}
else if (seconds >= secondsPerMinute && seconds < secondsPerHour )
{
minutesCalculated = seconds/secondsPerMinute;
JOptionPane.showMessageDialog(null, seconds + " seconds equals: " + minutesCalculated + " minutes");
}
else if (seconds >= secondsPerHour && seconds < secondsPerDay)
{
hoursCalculated = seconds/secondsPerHour;
JOptionPane.showMessageDialog(null, seconds + " seconds equals: " + hoursCalculated + " hours");
}
else if (seconds >= secondsPerDay)
{
daysCalculated = seconds/secondsPerDay;
JOptionPane.showMessageDialog(null, seconds + " seconds equals: " + daysCalculated + " days");
}
