Program Developement Cycle
|
1) Analyze the requirements
2) Design the solution 3) Validate the design 4) Implement the desing 5) Test he solution 6) Document the solution |
|
|
Analyze the requirements
|
- Review program specifics
- Meet w/ analysts & users - Indent program components |
|
|
Design the solution
|
- group activities into modules
- devise solution alg - design user interface |
|
|
validate the design
|
- test solution alg w/ sample data
- confirm w/ user that sol meets requres |
|
|
implements the design
|
- translate alg into code
- enter code in PC |
|
|
test solutoon
|
- test program
- debug - integration testing |
|
|
Document the solution
|
- review code
- review & revise internal doc - formalize/complete user doc |
|
|
benefits of OOP
|
1) reusability
2) stability 3) Easier design 4) Faster design |
|
|
OOP & OOD concepts
|
1) object
2) method 3) class--> instance 4) subclass 5) inherits 6) hierarchy 7) message 8) event 9) encapsulation 10) polymorphism |
|
|
JVM
|
interpreter executes bytecode. --> JVM
part of JRE |
|
|
Java API
|
pre-written classes, 50 predefined packages/class libraries. Found in JRE
|
|
|
java Applet viewer
|
display applets w/o version/enabling probs w/ internetish stuff, appletviewer.exe. part of JRE
|
|
|
Java Developement Tools
|
VATES, IDE, builder tools
|
|
|
API
|
application program interface, standard stet of interfaces/ class functionally grouped into packages.
|
|
|
Reusability
|
the classes are desinged so they can be reused in many systems, or modified classes can be created using inheritance
|
|
|
Stability
|
classes designed for repeated use/become stable over time,
|
|
|
class libraries
|
aka class packages, set pre-defined class packages.
