Thread: How to override abstract methods and use variables without making them public

So I have a class called student and one of the variables is tuition rate, i want to set the tuition in the other class but i dont want to make the variable public, (Its not that big of a deal at the moment but i would like to see if i could) is there a way to do it?

Heres my first part of code from the abstract Student class

 
public abstract void setTuition(double rateIn);
 
 
    public abstract double getTuition();
 
    abstract String Display()

now heres where im trying to override in the Undergraduate class

 
@Override
  public void setTuition(double rateIn){
       rateIn=200*super.getHours();
 
  }
 
 
 
 
  @Override
  public String Display(){
 
 
 
 
      return("name "+super.getLastName()+", "+super.getFirstName()+"\n"+
                         "ID "+super.getStudentId()+"\n"+
                         "Enrollment "+super.getHours()+"\n"+
                         "tuition $"+());
      //Here i need the variable so i can print it out
 
  }

All i need is a way to print out the variable

is there a way to do it?

Yes, use the get... and set.. methods to access and change the variable.

way to print out the variable

You need to have a reference to an instance of the class with the variable; then call the get... method for the variable:

  refToClass.getVariable()     // get the contents of the variable
