Java Examples

File(s)	Description	Topic(s)
Die.java & DieTest.java	Die Class Design Example	OO design & documentation, simple random number generation & use and GUI I/O.
Arm.java & Main.java	Arm Class Design Example	OO design & documentation, biomechanics example and console I/O.
WeightConverter.java & Main.java	Weight Converter Class Design Example	OO design & documentation, GUI I/O and Decimal Format class.
BetterTime.java	Improved Elapsed Time Class	OO design & documentation, the system.nanoTime() method, console I/O (using of Scanner class for input & PrintStream. printf() method for formatted output).
RanTest.java	Random Number Generator Demonstration	The Random class, selection (if) and repetition (for) statements, arrays, file I/O using Formatter class.
ObjParms.java	Object Parameter & Javadoc Example	Implications of Java's parameter passing and return behaviors with respect to primitive and object data. Also, javadoc style comments. A bit over-the-top, but very complete.
RainFall.java	Array Usage and File I/O Example	The Scanner class for file input, the Formatter class for file output and storing information in arrays.

Comments regarding these examples: Improved versions of the early examples would involve putting the test/demo code main() method in a non-public class in the same file as the class of interest; replacing the use of the DecimalFormat class with the String.format() and/or PrintStream.format() methods; replacing the use of the Math.random() method with the Random class; replace the use of the PrintStream.printf() method (old, C++ style name) with PrintStream.format() (new, Java style name).
