    Default How do you code to compare result?

     
    import java.util.Scanner; //import scanner statement
     
    public class InternetServiceProvider
    {
    	public static void main(String [] args)
    	{
    		Scanner keyboard = new Scanner (System.in); //scanner object
     
    		String service; //service package choice 
    		double hours; //hours used
    		double total; //total amount due
     
     
    		System.out.println("Package A: For $9.95 per month 10 hours of access are provided." +
    			" Additional hours\nare $2.00 per hour.\n"); //print service package A rate and price
    		System.out.println("Package B: For $13.95 per month 20 hours of access are provided." +
    			" Additional hours are\n$1.00 per hour.\n"); //print service package B rate and price
    		System.out.println("Package C: For $19.95 per month unlimited access is provided.\n"); //print service package C rate and price
    		System.out.print("Please enter a package you want(A, B, C): "); //prompt service package choice
    		service = keyboard.nextLine(); //accept service package input
    		System.out.print("Please enter hours used: "); //prompt hours used
    		hours = keyboard.nextDouble(); //accept hours used input
     
     
     
    		if (service.equals("A")) //if statement for service A package
    		{
    			if(hours <= 10)
    			{
    				total = 9.95; //total
                System.out.println("You are using " + service + " and you used " + hours +
    				" hours this month. Your total charge will be $" + total + "."); //print the result for 10 hours or less used
    			}
    			else
    			{
    				total = 9.95 + ((hours-10)*2); //calculate total
                System.out.println("You are using " + service + " and you used " + hours +
    				" hours this month. Your total charge will be $" + total + "."); //pritn the result for 10+ hours used
    			}
    		}
     
     
    		else if(service.equals("B")) //if statement for service B package
          {
             if(hours <= 20)
             {
                total = 13.95; //total
                System.out.println("You are using " + service + " and you used " + hours +
    				" hours this month. Your total charge will be $" + total + "."); //print the result for 20 hours or less used
             }
             else
             {
                total = 13.95 + ((hours-20)*1); //calculate total
                System.out.println("You are using " + service + " and you used " + hours +
    				" hours this month. Your total charge will be $" + total + "."); //print the result for 20+ hours used
             }
           }
     
     
          else if(service.equals("C")) //if statement for service C package
          {
             total = 19.95; //total
             System.out.println("You are using " + service + " and you used " + hours +
    				" hours this month. Your total charge will be $" + total + "."); //print the result
          }
     
    	}
    }

    ok. This is my initial code that suppose to prompt user to choose one of 3 internet service plans which are plan A, B, C and then how many hours user used it. It then prints out the total cost.
    Now, I am having problem. How do you alter this code to compare result from A to B and A to C. for example, user would get $29.95 if he choose plan A and use for 20 hours. But if he choose plan B and use for 20 hours, he would get $13.95. So how do I make this to compare those two prices and print out the difference? I was thinking about compareTo method but I only know how to do it with basic strings like comparing names. Can anyone help me out on this?

    how the heck is this spamming? you must be high or something. if you have nothing to say to help me, please just don't post. I had similar post but I was asking different question there and there was no option to remove or close previous post that i had answer to. I would report you for harrassing and trolling.

    That was a reply to the spammer, not to you.

    Chill out. I believe PhHein was responding to 9codeweb.

    However, you should notify us when you've posted the same problem in multiple places (crossposting) so that we don't waste our time repeating the same or providing contradictory advice to that being given somewhere else.
