Nested If Else statements in Java and my formatting them? (Beginner)

I am so sorry to bother anyone on here for this but I cannot seem to figure out why my code isn't running. I have tried searching the internet as well as my textbook but I am obviously missing something that probably staring me right in the face. Again I apologize for the simplicity of this. Any help is appreciated.

public class MannPass4 
{

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) 
    {
        // Declerations
        double packageA, packageB;
        double aPrice = 9.95, bPrice = 13.95, cPrice = 19.95;
        double hoursA = 10, hoursB = 20, rHours, holdOption, holdHours;
        final int A_ADDIT = 2, B_ADDIT = 1;

    holdOption = Double.parseDouble(JOptionPane.showInputDialog(null, "Enter the cuctomer's package (A, B, or C):"));

    holdHours = Double.parseDouble(JOptionPane.showInputDialog(null, "Enter the number of hours used:"));

        if (holdOption == 'A')
        {
        rHours = (holdHours - hoursA);
        packageA = ((rHours * A_ADDIT) + aPrice);
        JOptionPane.showMessageDialog(null, "The charges are "+ packageA);
        } 
        else if(holdOption == 'B')
        {
        rHours = (holdHours - hoursB);
        packageB = ((rHours * B_ADDIT) + bPrice);
        JOptionPane.showMessageDialog(null, "The charges are "+ packageB);
        }       

        else if (holdOption == 'C')
        {
        JOptionPane.showMessageDialog(null, "The charges are "+ cPrice);
        }

                else 
                {
                 JOptionPane.showMessageDialog(null, "Invalid choice, please choose either A, B, or C.");
                }     
        }    
    }
