3. Code Optimization: Yvonne V. Richardson, BSCS, M. Ed

Declare Variables Locally
Minimize Scope of Method Calls

4. Code Optimization Guideline 1
Use the MVC model to organize program code
Model - default
View - user interaction
Controller - main

5. Code Optimization Guideline 2
One method, one task
One task, one method

6. Code Optimization Guideline 3
Do not pass values to a method if it does not use them
Affects both the calling and the called module

Code Optimization: Yvonne V. Richardson, BSCS, M. Ed 6

7. Code Optimization Guideline 4
Declare variables (and objects) as locally as possible
Precondition – local construct – postcondition
Top of the class or method is reasonable and traditional

8. Code Optimization Guideline 5
Call methods (and objects) as low as possible
Stay within the MVC model
Scope affects object life
