Programming Question:

Complete exercise 10.18 from the text on page 389. Submit a word document with your solution. Make sure you do the two parts: 1) What does each legal and illegal statement tell you 2) Draw the diagram Hint: Java does not allow multiple inheritance

10.10 Summary 389 ise 10.16 Go back to the lab-classes project from Chapter 1. Add tructors to the project (every lab class can have many students and a single ). Use inheritance to avoid code duplication between students and instructors (both have a name, contact details, etc.) cise 10.17 Draw an inheritance hierarchy representing parts of a Exer computer system (processor, memory, disk drive, DVD drive, printer, scanner, keyboard, mouse, etc.). Exercise 10.18 Look at the code below. You have four classes (0, X, T, and M) and a variable of each of these. 0 0; T t; M m; The following assignments are all legal (assume that they all compile): m=x; o=t; The following assignments are all ilegal (they cause compiler errors o=x; x=0; hat diagram can you say about the relationships of these classes? Draw a class Exercise 10.19 Draw an (direct inheritance hierarchy of AbstractList and all ts and indirect) subclasses as they are defined in the Java standard library
