Anybody with English as a first language?
I'm going thru K&B 6 Master Exam part one questions and question 50 have following statement:
"is-a relationships always rely on inheritance" and indicate that true is correct answer for this statement
How can is-a ALWAYS rely on inheritance when my understanding that SOMETIMES it can rely on interface.
For example if class A implements interface B then we can say that "A is-a B"???
