Warm up quiz

Lab 7 on 10/12 :

Midterm test, 120 minutes.

Object & Class

Lab 8 on 10/19:

1. Explain the solution and grading for practice problem of homework 5 if there is any question from students.

• Development of Static Method  

• The print-out results of 5 programs.
• MethodSignature.java with four methods.

by Friday 11/4,11:59pm. 

Now, you must have a complete view of  how the computer calls a (static) method (from inside or outside of the class where it is defined) and the scope of variables declared inside this method (including array), from tracing the program with a nested call,  the overloading, and the parameter(s). Students you should be able to apply the procedural decomposition and achieve the method signature in some simple situations.     

Homework 7: Practice problem on Method Development (pdf, doc). Please submit the following work by Friday 11/11, 11:59 pm.

• Trace of 2 programs ReferenceSematnics and NestedCalls.
• StringWalkthrough.java (Walking through step by step, only the final version is needed)
• PrimeWalkthrough.java (Walking through step by step, only the final version is needed)
• Taste.java (final version only)
• PrintSteps.java

Now, you must have a tast of decomposition in coding the (static) method. It is a space and timing issue, for so many lines of code occupying the computer memory to support a call from any time in the excution when it is needed. The efficieny of such a support relies on how widely and how many different cases you had considered in the decomposition (generalzing the procedural abstraction).
