Add a loop to verify input. Repeat the prompt if the input is zero or a negative

Question

Add a loop to verify input. Repeat the prompt if the input is zero or a negative value. A second loop is needed to allow the program to repeat when “yes” is entered ignoring the case. Shown below is an example of the program executing.

Here is what I have so far

public class LabAssign5 {

  
public static void main(String[] args) {
// TODO code application logic here
long numSeconds;
String numOfSecondsString;
while (true) {
numOfSecondsString = JOptionPane.showInputDialog("Enter the Number of Seconds:");
numSeconds = Integer.parseInt(numOfSecondsString);
}
  
  
  
JOptionPane.showMessageDialog(null, "You eneterd " + numSeconds + " seconds ");
long numOfDays;
long remainingDays, numOfHours, remainingHours, numOfMinutes;
numOfDays = numSeconds / 84600;
remainingDays = numSeconds % 84600;
  
numOfHours = remainingDays/3600;
remainingHours = remainingDays % 3600;
  
numOfMinutes = remainingHours/60;
  
JOptionPane.showMessageDialog(null, "Days = " + numOfDays + " Hours = " + numOfHours + " Minutes = " + numOfMinutes + " Seconds = " + numSeconds );
  
  
}
}

Explanation / Answer

Here is the code:

import javax.swing.JOptionPane;

public class TestApp {

public static void main(String[] args) {

TestApp testAppObj = new TestApp();

testAppObj.convertSecondsToDays();

}
  

public void convertSecondsToDays()

{

// TODO code application logic here

long numSeconds = 0;

String numOfSecondsString,continueOrNot;

while (numSeconds <= 0) { // Run loop until a valid value entered.

numOfSecondsString = JOptionPane.showInputDialog("Enter number of seconds: ");

numSeconds = Integer.parseInt(numOfSecondsString);

}   

JOptionPane.showMessageDialog(null, "You eneterd " + numSeconds + " seconds ");

long numOfDays;

long remainingDays, numOfHours, remainingHours, numOfMinutes;

numOfDays = numSeconds / 84600;

remainingDays = numSeconds % 84600;   

numOfHours = remainingDays/3600;

remainingHours = remainingDays % 3600;   

numOfMinutes = remainingHours/60;

JOptionPane.showMessageDialog(null, "Days = " + numOfDays + " Hours = " + numOfHours + " Minutes = " + numOfMinutes + " Seconds = " + numSeconds );

continueOrNot = JOptionPane.showInputDialog("If you want to continue, type "yes": ");

if(continueOrNot.equalsIgnoreCase("yes")) // loop for continuation

{

convertSecondsToDays();

}

else

{

return;

}

}

}
