Three hours – I can easily speak for three hours Organization Three hours – I can easily speak for three hours you may have trouble listening! Plan A break at 15:20 for 15 minutes In the break you can collar me and ask questions. Recommendation The only way to slow me down is to ask questions. Introduction

ASK QUESTIONS … ANSWER QUESTIONS ASK QUESTIONS … Preliminaries You are know doing an MSc – I am not teaching you, you should be organising your time to gain the knowledge you need to complete your MSc. We do two things – a guide as to the knowledge that you should be pursuing. A resource for the acquisition of that knowledge. So ask me questions – and respond to the questions I ask you. If I get three answers and ask the class to vote on it – I am not noting which way you vote, so don’t abstain. Go for the answer which you think is most likely – vote at random if necessary. I ask easy questions, but some of the time they are there to expose difficulties that I have found in the course. Either from my memories of learning Java of from the responses of classes which I have taught. Frequently I want a wrong answer, because it helps to draw out a point – if I say “many people are confused at this point and think ….” you will nod and it will drift over”. If you have given an answer which incorporates that misapprehension, then it you have incorporated that knowledge into your mind and when I try to explain the real situation you have a better chance of understand and remembering.

OO Design Introduction In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved. Algorithms are not thought of as design patterns, since they solve computational problems rather than design problems. Wikipedia Introduction
