Introduction to Programming

what is bluej
What is BlueJ?
  • A development environment for Java
  • Aimed at novice programmers, but not a cut-down version of Java
  • Allows us to get to grips with “objects first”
  • Allows us to create and interact with objects before getting to grips with Java syntax

Introduction to Programming

general information
General Information
  • Three lectures per week.
  • There will be a (multi-part) assessed programming exercise.
  • Instructions for submission will be given later.
  • Everyone attends at least one two hour programming lab each.
  • Lab assignments are not to be handed in.
  • Help with these will be given at the lab classes.
  • Some of the lectures may be used to discuss solutions to exercises.

Introduction to Programming

assessment
Assessment

Coursework (handed in this term) worth 50%

  • A multi-part programming exercise that builds towards a single program:
    • each part will have a separate submission deadline
    • each part will consist of the code from the previous part plus some new code
    • the mark for each part will be the mark for this new code, independent of the previous part
    • initial feedback will be given for each part after the deadline
    • the model answers to previous parts can be used in subsequent parts
    • the whole lot will be marked after the final submission
    • your final coursework mark will be computed by adding up your marks for each part
  • Exam (in Summer term) worth 50%

Introduction to Programming

goals
Goals
  • Sound knowledge of programming principles
  • Sound knowledge of object-orientation
  • Able to critically assess the quality of a (small) software system
  • Able to implement a small software system in Java
  • Able to program well enough in Java to form basis for other courses

Introduction to Programming

why java
Why Java?
  • Designed with Internet applications in mind
  • Rapidly becoming one of the most important programming languages (along with C and C++)
  • Object Oriented - encourages very disciplined programming in terms of “objects” and their behaviours
  • Architecture neutral and portable - will run with the same behaviour on any processor and under any operating system

Introduction to Programming

applications and applets
Applications and Applets
  • There are two types of Java program:
    • Applications are just like any normal computer program which you execute by giving an appropriate command to the operating system
    • Applets are programs which execute from within a web browser. The browser downloads the (compiled) Java program from the web page, and runs it on your machine.
  • This course will concentrate on applications.

Introduction to Programming

java which version
Java - which version?
  • About 8 years ago, Java underwent a major revision (version 1.0 to 1.1)
    • changed various features of the language
    • It was a major functional change
  • More recently we’ve seen Java 1.2, 1.3, 1.4, and in the last couple of years 1.5 (aka Java 5) and 1.6 (Java SE 6).
  • Java 5 made some notable functional changes to the language, introducing e.g. for each loops and generic classes.
  • The change to Java SE 6 is less visible as far as we are concerned.
  • We will be using the third edition of Objects First with Java, which uses Java 5.
  • In the labs we will be running code with Java SE 6.

Introduction to Programming

the structure of java
The Structure of Java
  • Java is made up of the basic language plus lots of packages (libraries) containing useful facilities:
    • java.lang is included automatically
    • other official packages have to be explicitly importedinto your program
  • local and other 3rd party libraries also have to be imported.
