In chapter 4 we start to get into some of the more fun items. Of course we had our standard chapter in Object-Oriented Programming and then continued discussions on Ploymorphism, Inheritance, Overloading, Interfaces and touched a little on collections.
The lab was a enjoyable. It was a continuation of the Fraction application from Chapter 3. We added in a Compound Fraction class which inherited from the Fraction class and also utilized overloading to handle the new ToString requirements. We also created a collection where we added, displayed contents and cleared Fraction objects from.
Once again the code descriptions from the book would not compile. But thank god for a great little tool that helped me determine the difference from my code and the code from the solution. The tool is called Beyond Compare and can be found at: http://www.scootersoftware.com/
Chapter 5 should go fast it basically covers Debugging and Testing. More tales from the MCAD certification path to follow………
