Tools that Facilitate the Development Process

Text formating - layout - indentation Syntax highlighting - keywords Debugging facilities Project management Version control Rapid application development RAD Documentation integration

TextPad - a text editor with Java support utilities

Netbeans - an Integrated Development Environment ( IDE )

Steps in creating a program

write source code / script compile source ( run script) debug ( syntax errors) compile execute test debug ( semantic & logical errors ) execute / test

Program Errors

Syntax (compile time) Errors in the way the code is written - missing ; keywords

mispelled, lower / uppercase errors Semantic ( run time)

Errors in program meaning - assigning an integer to a string type, file read/write io errors, arrays out of bounds errors

Logical Errors in program calculation - incorrect output from

given input - program works but output results not reliable

Lottery Scenario User enters six numbers - what restrictions?

Six numbers, range 1..49, all unique, Computer system selects a set of numbers

Same criteria + a bonus ball Selections are compared Display message depending on outcome of

comparison All within a multimedia context!

LotteryDraw Classselect a random number between 1..49store in first array element

while numbers to choose < 6select a random number between 1.49if number already chosen

select a random number between 1..49else

end while

LotteryDraw Class

Chooses 7 unique random numbers between 1..49

Storyboarding

Traditional Storyboading A storyboard is a graphical representation such as a

series of illustrations or images displayed in sequence for the purpose of visualizing a motion sequence or interactive media sequence

The storyboarding process in the form as used today was developed at the Walt Disney studio during the early 1930s

Storyboarding became popular in live-action film production during the early 1940s

Animatic Simplified mock-ups called animatics give a better

idea of how the scene will look with motion Usually a series of still images edited together and

displayed in sequence Additionally a rough dialogue or sound track is added

to the sequence of still images (usually taken from a storyboard) to test whether the sound and images are working well together

Storyboarding in Software& Interface Design

The term ‘storyboard’ is also used in the field of software development to present and describe interactive events

Also provide information about components on user interfaces which serve to indicate the functionality of a given device
