00:00:01.005 --> 00:00:04.118
In this demo I'm going to look at the NetBeans IDE

2
00:00:05.111 --> 00:00:07.113
currently open in my IDE

3
00:00:07.114 --> 00:00:09.115
is a version of the adventure game program

4
00:00:09.116 --> 00:00:12.111
which has been created as a NetBeans project.

5
00:00:14.004 --> 00:00:16.001
The classes in the project are shown 

6
00:00:16.002 --> 00:00:17.222
in the projects window here

7
00:00:18.111 --> 00:00:21.004
unlike BlueJ NetBeans doesn't show classes

8
00:00:21.005 --> 00:00:22.226
in the form of a class diagram.

9
00:00:25.007 --> 00:00:27.001
Note that the classes in this project

10
00:00:27.002 --> 00:00:29.004
are organised into packages

11
00:00:29.111 --> 00:00:31.117
you can see here the symbol for a package

12
00:00:31.118 --> 00:00:33.111
and the classes inside it.

13
00:00:33.222 --> 00:00:36.114
A package is a group of related classes

14
00:00:37.002 --> 00:00:40.005
the test classes in this program have been split into

15
00:00:40.007 --> 00:00:43.115
a separate package from the rest of the classes

16
00:00:43.226 --> 00:00:46.229
you'll learn more about packages in Java shortly.

17
00:00:48.225 --> 00:00:52.002
The Game class has a green arrow symbol on its icon

18
00:00:52.009 --> 00:00:54.223
and that shows that it contains the main method

19
00:00:54.225 --> 00:00:56.223
as an entry point for this program.

20
00:00:59.223 --> 00:01:02.228
The navigator window down here shows the methods

21
00:01:02.229 --> 00:01:06.112
the constructor in the currently selected class

22
00:01:08.009 --> 00:01:10.002
the editor window is up here

23
00:01:10.004 --> 00:01:12.110
and I can open more than one class for editing

24
00:01:12.113 --> 00:01:15.224
at the same time if I open the item class

25
00:01:16.002 --> 00:01:18.227
that appears as a new tab in the editor window

26
00:01:19.116 --> 00:01:21.224
note that the navigator now shows me the methods

27
00:01:21.225 --> 00:01:23.115
of the Item class.

28
00:01:26.116 --> 00:01:28.226
The output window down here is equivalent

29
00:01:28.227 --> 00:01:31.009
to the terminal window in BlueJ

30
00:01:33.113 --> 00:01:36.116
NetBeans has a lot more menu options and icons

31
00:01:36.117 --> 00:01:38.224
throughout its interface than BlueJ does

32
00:01:39.001 --> 00:01:40.222
and thats because its a lot more powerful, it

33
00:01:40.222 --> 00:01:42.224
does a lot more than BlueJ

34
00:01:43.114 --> 00:01:45.113
it can take a bit of getting used to though

35
00:01:45.220 --> 00:01:48.223
in order to learn to make full use of its capabilities.

36
00:01:50.118 --> 00:01:52.225
I'm now going to run the adventure game program

37
00:01:52.228 --> 00:01:56.002
and I can do this in a number of ways, I can right click

38
00:01:56.006 --> 00:01:58.001
and the class that has the main method 

39
00:01:58.002 --> 00:01:59.113
and choose run file

40
00:02:00.115 --> 00:02:02.228
I can choose the run menu

41
00:02:03.008 --> 00:02:05.115
and the run project option

42
00:02:06.005 --> 00:02:10.114
or I can simply click the run icon here, lets do that

43
00:02:12.112 --> 00:02:15.222
and the program runs and I can interact with it

44
00:02:25.227 --> 00:02:27.229
and now the program is terminated.
