Java Programming Fundamentals - sample programs from "hello world" through to objects, inheritance, arrays, packages and utility classes!

This week, I'm running a small Learning to Program in Java course ... and I have taken advantage of the small group size to write a co-herent series of new examples of the basics - showing not only how code works, but also how it is developed. I've uploaded all the examples into a single module, and they're also available through the following links

Adam.java	Hello World, and command line input
Bernie.java	static method (function) calls
Chloe.java	First use of variables and conditionals
Daniel.java	Integer Calculation
Edward.java	Shared code - load and run method from another class
Fred.java	Reading user input from keyboard
Glenda.java	loop, with break and continue
Hilary.java	Passing values in and out of a local method
Irene.java	Arrays - setup, fill, pass, process, length
Julie.java	Array of arrays (i.e. 2 dimensional array)
Keith.java	Using a class
Lenny.java	Static Methods, comparing objects
Margaret.java	String handling example
Niamh.java	loading a method from a class in a package
Orlando.java	Class within a package
Peter.java	underlying (base) class
Quentin.java	Calling in an extended class
Rolf.java	Extended class
Steve.java	A second extended class
Time.java	Base class for examples up to Lenny
Trevor.java	Polymorphism - an array of different objects
Ulrika.java	An array of objects
Viv.java	An ArrayList - an extendable array
WellHouseInput.java	Reading from the keyboard or a file
