ch 2 post

in ch 2 we leaned a lot about objects and how they work with classes, intences, and methods. there is a real class whose objects we wont to use and theirs tester classes that test for objects. classes can inherit instance variables. in this chapter they put us thought an interesting scenario of two guys writing the same code but in different ways to show the difference with methods.we learned how the classes can be broken down in to super classes and sub classes. super classes are more abstract when sub classes are more spicfic to the method being performed. they started to talk more about OO programming and what was effective about it. objects can also be able to executed task given to them to preform differently.
