Sum Of Numbers

Im trying to write a program that asks the user for a positive nonzero integer value. The program should use a loop to get the sum of all the integers from 1 up to the number entered. For example, if the user entered a 50, the loop will find the sum of 1,2,3,4,....50.

i think the code i posted may be wrong but ive spent hours trying to figure it out and my teacher isnt helpful at all. :(

i really would appreciate it if a full solution code is posted. This will help me study for my other programs im having trouble with.
public class SumOfNumbers
{
        public static void main( String [] args)
        {
                
            double nonZero;
            double numbers;
            double totalNumbers;
            String input;
                
        
            for( int count = 1; count <= nonZero; count++ )
            {
                input = JOptionPane.showInputDialog(null, "Please enter a nonzero positive integer.");
 
              nonZero = Double.parseDouble(input);
 
            }   
                
            JOptionPane.showMessageDialog(null, "The sum of the integers is: " + nonZero);
        }
}

Not sure if this will work since I don't have a java environment to test in ATM, but it has comments so you can see what it is supposed to do.
public class SumOfNumbers
{
        public static void main( String [] args)
        {
            double number; // The entered number after it is parsed
            double totalNumber = 0; // Total after adding
            String input; // Input from the input dialog
                
            input = JOptionPane.showInputDialog(null, "Please enter a nonzero positive integer."); // Ask for the number
            number = Double.parseDouble(input); // change it to a number
            for( int count = 1; count <= number; count++ )
            {
              totalNumber += count; // Loop through and keep adding the numbers
            }   
                
            JOptionPane.showMessageDialog(null, "The sum of the integers is: " + totalNumber); // Show the final
        }
}
