Nested if statements not executing

I am doing a practice internet service provider java question and my inner if statements are never executing.

Every time I run the program, charges still equals 0.

Here is my code

     int HoursUsed;
     String packageChoice;
     double charges = 0;

     packageChoice = JOptionPane.showInputDialog("Enter the customer's package (A, B, or C):");
     HoursUsed = Integer.parseInt(JOptionPane.showInputDialog("Enter the number of hours used:"));

     if (packageChoice == "A"){
        if (HoursUsed < 10) {
           charges = 9.95;
        } else {
           charges = (HoursUsed - 10) * 2 + 9.95;
        }
     }else if (packageChoice == "B"){ 
        if (HoursUsed < 20){
           charges = 13.95;
        }else{
           charges = (HoursUsed - 20) + 13.95;
        }
     }else if (packageChoice == "C"){
        charges = 19.95;
     }

     JOptionPane.showMessageDialog(null,"The charges are " + charges);
