    Default Accessability/Visability Private

    This is part of a assignment, I was instructed to make a variable in a class 'A' private. Class 'B' extends class 'A' and class B uses the variable in class A that I declared private. Now I am going to receive an error message until I deal with the usage of this variable.

    How can a class B object get access to this private variable of class A without changing the accessibility/visibility of the variable?

    Here is a snippet of the code, the variable is "text"

    tokenizer = new StringTokenizer(text, " ");

    Default Re: Accessability/Visability Private

    Are you allowed to modify class A? If so, I would add what is known as a "getter" method. In essense, it simply returns the value of the variable you want.
    public class A
    {
         private int num;
         // the getter method
         public int getNum()
         {
              return this.num;
         }
    }
