In this session we point you at the Java Library, and go into some more details on how Strings work. We also introduce the HashMap class (a very useful type of collection).

In this session we look more closely at the way that Java deals with variables, and in particular with the differences between primitives (basic types like int and char) and objects. We also take an initial look at the scoping rules in Java, which dictate the visibility of variables in your program

In this lecture we look at key concepts in Java: how to write, compile and run Java programs, define a simple class, create a main method, and use if/else structures to define behaviour.

What is Programming? A useful definition Object Orientation (and it’s counterparts) Thinking OO Programming Blocks Variables Logic Data Structures Methods

Instance Variables Local variables Cool 3D Modelling! “this” keyword

Exceptions An Example The Throws keyword Try and Catch The flow Multiple exceptions Finally How exceptions are thrown What the complier checks Handle or Defer Recovery Writing your own

Static Types of methods Instance Static Example Calling Static methods Why Static Final

A quick word about abstract How a class interfaces Making Pets The Deadly Diamond of Death Interfaces (not interfaces)

Which methods are where? Overriding Calling super’s methods Coupling and cohesion

Inheritance Code duplication Super classes Constructors Polymorphic collections “Anywhere a super class is, a sub class can go” Casting A great deception

ArrayList ArrayList vs Array Declaration Insertion Access Removal Wrapper classes Iterator object

Looping while do while for Arrays indexes For each loop

Banking Parameters and arguments Passing Objects Primitives Returning Getters and Setters

Constructors With one parameter With two parameters Overloading Constructors and methods

Variables - Objects and Primitives, Quick look at scope
