00:00:01.111 --> 00:00:02.118
Welcome to week one

2
00:00:02.221 --> 00:00:06.221
Introduction to object-orientated programming.

3
00:00:10.119 --> 00:00:12.228
The difference between a computer and other

4
00:00:12.229 --> 00:00:16.112
simplier electronic devices is that a computer can be programmed

5
00:00:16.228 --> 00:00:19.227
many devices contain electronic circuits that are

6
00:00:19.228 --> 00:00:22.006
designed to do one specific job only.

7
00:00:22.223 --> 00:00:24.005
A computer on the other hand 

8
00:00:24.006 -->00:00:26.227
can be instructed in principal to do any job

9
00:00:27.115 --> 00:00:30.118
the designer of the computer does not what jobs it will be

10
00:00:30.119 --> 00:00:33.221
required to do until after it has been built.

11
00:00:34.111 --> 00:00:36.112
The computer does jobs under the direction

12
00:00:36.113 --> 00:00:39.005
of sets of instructions known as programs.

13
00:00:40.004 --> 00:00:42.006
By running a different program the computer

14
00:00:42.007 --> 00:00:44.006
could be made to do a different job.

15
00:00:45.114 --> 00:00:48.003
Creating these instructions is known as programming

16
00:00:48.008 --> 00:00:50.110
the instructions that make up a program

17
00:00:50.111 --> 00:00:53.005
are written in a programming language.

18
00:00:57.118 --> 00:00:59.117
This week you will start to learn about 

19
00:00:59.118 --> 00:01:02.005
the process of computer programming and it's importance 

20
00:01:02.006 --> 00:01:04.116
to computing professionals.

21
00:01:05.005 --> 00:01:09.006
The programming language that you will learn to use in this module is Java

22
00:01:09.221 --> 00:01:12.228
like many of the most widely used programming languages today

23
00:01:13.006 --> 00:01:16.111
Java is an object-orientated programming language

24
00:01:17.110 --> 00:01:20.114
object-orientated programming is an approach to designing

25
00:01:20.115 --> 00:01:23.112
in creating programs that is particularly useful

26
00:01:23.113 --> 00:01:26.114
for computer systems that need to do complex jobs

27
00:01:26.222 --> 00:01:28.229
as many real world systems do.

28
00:01:29.229 --> 00:01:31.116
You will start to learn this week

29
00:01:31.117 --> 00:01:36.004
about some of the important ideas and concepts in object-orientated programming

30
00:01:36.115 --> 00:01:39.226
which you will then go on to apply throughout the module.

31
00:01:40.222 --> 00:01:42.223
You will also be introduced to BlueJ

32
00:01:42.224 --> 00:01:45.002
the software that you will use throughout the module

33
00:01:45.003 --> 00:01:48.005
to help you write and test your own programs.
