Thread: why wouldn't it print my code?

import java.util.Scanner;
 
public class InternetServiceProvider
{
	public static void main(String [] args)
	{
		Scanner keyboard = new Scanner (System.in);
 
		String letter;
		double hours;
		double total;
 
 
		System.out.println("Package A: For $9.95 per month 10 hours of access are provided." +
			" Additional hours\nare $2.00 per hour.\n");
		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");
		System.out.println("Package C: For $19.95 per month unlimited access is provided.\n");
		System.out.print("Please enter a package you want(A, B, C): ");
		letter = keyboard.nextLine();
		System.out.print("Please enter hours used: ");
		hours = keyboard.nextDouble();
 
		if (letter == "A" || letter == "A")
		{
			if(hours <= 10)
			{
				total = 9.95;
            System.out.println("You are using " + letter + " and you used " + hours +
				" this month. Your total charge will be $" + total + ".");
			}
			else
			{
				total = 9.95 + ((hours-10)*2);
            System.out.println("You are using " + letter + " and you used " + hours +
				" this month. Your total charge will be $" + total + ".");
			}
		}
		else if(letter == "B" || letter == "B")
      {
         if(hours <= 20)
         {
            total = 13.95;
            System.out.println("You are using " + letter + " and you used " + hours +
				" this month. Your total charge will be $" + total + ".");
         }
         else
         {
            total = 13.95 + ((hours-20)*1);
            System.out.println("You are using " + letter + " and you used " + hours +
				" this month. Your total charge will be $" + total + ".");
         }
       }
      else if(letter == "C" || letter == "C")
      {
         total = 19.95;
         System.out.println("You are using " + letter + " and you used " + hours +
				" this month. Your total charge will be $" + total + ".");
      }
 
	}
}

As you can see, this problem, you have to make user to prompt internet service A, B, or C and number of hours used and print the total. When I compile, it compiles but it doesn't print the result at all. if I place println outside of brace, it tells me total is not initialized. What's wrong with my code and why wouldn't it print the result?

Give an example of your input and what does it output

when i use "=", it says i need boolean. how do I put boolean here?
