All, I am new to this forum and I am hoping I came to the right spot…. I am having trouble with this simple program. What I am attempting to do is simply work with dialog boxes and user inputs. My end state for this current segment is to simply have this output happen when I run the program:

Dialog Box: Enter the customer's package (A, B, or C);

User input: A

Dialog Box: Enter the hours used:

Any overages in hours need to be added as additional charges. For example Package A has a maximum of 10 hours access. Additional hours are $2.00 per hour. So if a user input 11 hours for Package his total would be $11.95. It needs to be adjustable of course with user input for hours. I am not sure how to do this? Any input would be greatly appreciated.

Dialog Box/Message: The charges are "total with hours input."


Thank you in advance

Problem is you're mixing Swing with Scanner. Use one or the other but not both.

public class Hmk {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        String res = JOptionPane.showInputDialog("Enter Package:");
        if (res != null && !res.trim().isEmpty()) {
            if (res.equals("A")) {
                JOptionPane.showMessageDialog(null, "9.95", "Price: ", JOptionPane.INFORMATION_MESSAGE);
            }
        } else {
            //invalid input.. user entered nothing.. do something here..
        }
    }
}

Also, to highlight code on the forum, use the Highlight tags:

Hey, a Scanner is for the console input. The joptionPane is a standard gui. Both are used to get a user input. It's up to you now which one you want to use. Please use the code tags next time. For java:

 and 

without spaces

import javax.swing.JOptionPane;

public class MonthlyDraft {

	public static void main(String[] args) {

		char packageSelect;
		final double Package_A = 9.95;

		String input = JOptionPane
				.showInputDialog("Enter customer's package (A, B or C):"); 

		System.out.println("You entered: " + input); // to debug the input
		packageSelect = input.charAt(0);
		if (packageSelect == 'A') {
			JOptionPane.showMessageDialog(null, "The charges are " + Package_A);
		}
		System.exit(0);

	}

} 

Great help!!! Thank you…I was able to work it out…..
