This section is a repository for code fragments and programs, for illustration purposes.

Please create a specific page for each example. Its WikiWord should end with the word Example.

Examples for novices

HelloWorldNoviceExample: Setup, compile and run Hello World.

AckermannNoviceExample: Setup, compile and run Ackermann's function.

FiboNoviceExample: Setup, compile and run Fibonnaci function.

Examples for beginners

HashBeginnerExample: HashMap with type parameter <String,Cell>

ListsBeginnerExample: ArrayList with type parameter <int>

MethcallBeginnerExample: Define a class and subclass.

ObjinstBeginnerExample: Import Nice classes from MethcallBeginnerExample.

RandomBeginnerExample: Import a standard Java package.

ShapesBeginnerExample: Alternative ways to define methods.

SieveBeginnerExample: Type inference for array variable.

StrcatBeginnerExample: Type inference for object variable.

SpellcheckBeginnerExample: Anonymous functions help reduce boiler-plate code.

MomentsBeginnerExample: Read numbers from a file and compute basic statistics.

ProducerConsumerBeginnerExample: Simple producer consumer thread synchronization.

CollectionExample: How to use collections with generic types.

Examples for intermediates

MethcallIntermediateExample: Define a Java class JavaToggleExample and subclass it in Nice, compile Nice using classes in a Java jar, setup a Nice executable archive classpath to find a Java jar - compare with MethcallBeginnerExample.

WordfreqIntermediateExample: Read words from a file and compute word frequencies - generic HashMap and ArrayList, sort, local functions.

ShapesIntermediateExample: Extend existing ShapesBeginnerExample classes to implement an abstract interface and new methods.

MethcallIntermediateTwoExample: Define a Nice class NiceToggleExample and subclass it in Java - compare with MethcallBeginnerExample.

Examples for benchmarkers

TreeVisitorIntermediateExample: Benchmark comparison between the Java Extensible Visitor pattern and modular extension in Nice. Simple generic binary tree TreeVisitorClassesIntermediateExample extended with a subclass representing n-ary trees, and with 3 different external methods.

DispatchIntermediateExample: Benchmark comparison between typecase and double-dispatch in Java, and multiple dispatch in Nice.

BenchIntermediateExample: Martin Richards systems language benchmark Bench, written in an ordinary OO style. PacketBenchExample declares enums, TcbBenchExample uses a class initializer, SchedulerBenchExample misuses enum.hashCode, TaskBenchExample declares an interface. "Benchmarking Java with the Richards benchmark" provides some background information.

More advanced examples

HelloSwingWorld : shows how to write (a little more complex :-) helloworld program.

SwingLibraryExample : shows how to write a GUI program using the Swing Library.

HaskellPreludeExample: Selected parts of the Haskell prelude, lots of functions which are useful when programming in functional style.

LazyVectorExample: A Vector subclass which computes its elements as they are they requested.
