Question

Example : How would I make furtherSpecificProcessing method a private method?

Reason: I would like to be able to new an object of type B or C and only have doStuff() visible to programmer. while at the same time class B and C supply the additional functionality

abstract class A
{
  protected abstract void furtherSpecificProcessing();

  //concrete method utilizing abstract method
  public void doStuff()
  { 
   //busy code
   furtherSpecificProcessing();
   //more busy code
  }

public class B extends A
{
  public void furtherSpecificProcessing
  {
    //Class B specific processing
  }
}

public class C extends A
{
 public void furtherSpecificProcessing
 {
   //Class C specific processing
 }
}

Answer 1

Override furtherSpecificProcessing() as protected, not as public in extending classes.
