Ch. 7 Lecture Notes - Designing classes according to object-oriented principles such as cohesion and coupling.

Demo Programs

• Ch7DemoSwap - swapping variables with a Pair class since Java only passes by value
• Ch7DemoStaticStuff - illustrates use of static methods, a static field, scope of variables and properties, & passing by value
• Ch7DemoFish - a warm-up version of Marine Biology
• tutorial on methods - great tutorial on instance & static methods with several exercises by Ms. Hartsook - http://techcenter.davidson.k12.nc.us/methods.htm
• MultipleClasses - multiple classes in one source file

Worksheets

• Ch. 7 Worksheet #1 - designing a class but not implementing it
• Ch. 7 Packet #1 - sample AP-style multiple choice questions (see Mr. Minich for this handout)
• Ch. 7 Packet #2 - sample AP-style multiple choice questions (see Mr. Minich for this handout)

Programming Assignments

• Ch7Proj1 - implementing a Fish move method & default constructor that provides unique id numbers
• Ch7Proj2 - two Fish objects that cannot move to the same location
• Ch7Proj3 - two Fish objects in a bounded environment
• Ch7Proj4 - dying fish
• Ch7Proj5 - SlowFish
