| Hello everyone.Welcome to the tutorial on '''Introduction to Netbeans IDE'''.

|00:06

|In this tutorial, I will introduce you to the basics of getting started with '''Netbeans'''.  

|00:13

|'''Netbeans''' is a free and '''open-source''' '''Integrated Developement Environment''', available at '''www.netbeans.org'''.

| 00:23

| It allows for '''integration''' of various components.

|00:27

|Supports various scripting languages and advanced '''text editor'''s.  

| 00:31

|It also provides a 'GUI' to create and design projects and also supports databases.  

| 00:39

|To finish this tutorial, basic knowledge in the Java programming language is necessary.  

|00:47

| 00:52

|To get started with Netbeans-

| 00:55

| I am using the '''Linux operating system Ubuntu''', version '''11.04'''

|01:00

|and '''Netbeans IDE''' version '''7.1.1'''.

|01:05

|In this tutorial, we will: * look at the installation of Netbeans  

|01:16

|create a sample Java project.  

|01:19

|Let us first look at installing the '''IDE'''.  

| 01:22

|Netbeans can be downloaded from '''netbeans.org.'''

| 01:27

|It is official main site.

| 01:31

|Click on the "'''Download'''" link on the main page of the site.  

|01:36

|01:39

|click on the ''''Download' link''' in the last column which includes the download of all the supported technologies that is required by the IDE including the '''Glassfish Server.'''  

|01:53

|The installation of '''Netbeans''' also requires the installation of the '''Java Development Kit (JDK)''' which can be downloaded from '''java.sun.com. '''

|02:05

|Click on the Get Java link here and select the link to download both the '''Netbeans''' and 'JDK' Bundle.  

|02:19

|select the '''setup''' file which is compatible with your '''operating system'''.

|02:24

|On Ubuntu, the setup-file is downloaded as a  ''''.sh' (dot sh)''' file  

| 02:29

|i.e as a '''shell script''' file.  

|02:38

|Navigate to the '''window''' or directory which contains the downloaded setup file and at the prompt,

|02:46

| type "'''sh'''" followed by the name of the downloaded file and press '''Enter'''.

|02:54

|This will start the '''installer''' which will take a few moments.

| 03:04

|The '''installer''' appears on the '''screen'''.

| 03:06

|You can follow the onscreen instructions to install the '''IDE''' on your system.

| 03:13

|I will exit the '''installer''' now.

| 03:17

|Let us now look at the '''Netbeans window'''.  

|03:21

| To open or launch Netbeans on your Ubuntu Operating System-

|03:25

| Go to the menu item '''Applications >> Programming''' and click on the '''Netbeans IDE''' icon.

|03:34

|When you first launch the IDE, it opens the '''Netbeans start page'''.

|03:41

|The '''IDE window''' contains

| 03:43

|menus in the menu bar,

| 03:46

|'''toolbar'''s and

| 03:48

|'''workspace'''s like the '''file system window''',

|03:52

|the '''run time''' window and the '''output window'''.

| 03:57

|The ''' main menu''' provides most of the '''command'''s you need to use Netbeans with, including-

|04:03

|creating, editing, compiling, running and debugging your projects.

| 04:10

| The '''tool bar''' which is present below the menu bar  provides buttons for several frequently used commands on the menu bar.  

| 04:18

| 04:23

| such as editing in the workspace window , '''execution, output''' or debugging- which is present below the workspace.

|04:35

|Let us next create a Sample Java Project.  

|04:40

|To create a java project, go to the '''File''' menu, click on '''New Project'''.

|04:47

|In the ''''New project' Wizard box''', under '''Categories ''',

|04:51

|select '''Java'''. Under '''Projects''', select '''Java Applications''' and click '''Next'''.

|04:58

|In the '''Name and Location''' page  of the wizard,

| 05:02

|give your '''Project Name''' as "KeyboardReader".

| 05:08

|Set the '''Set as Main Project''' check-box selected and   

|05:12

|click '''Finish'''.  

| 05:15

| 05:20

|Once the project is created, you should be able to  see the '''Projects''' window on the left  side of the IDE windows

| 05:27

| which contains a '''tree view''' of the components of the '''project''' including the '''source files, Libraries''' that your '''code''' depends on.

| 05:36

|The '''Source Editor''' is on the right with a file called  as  '''KeyboardReader.java ''' opened.

| 05:43

|Now, in the '''main class''', let us enter a sample '''java code'''.

| 05:49

| This code reads '''input''' from the keyboard and gives an '''output''' indicating if the input is a whole number or a '''floating point number'''.

| 05:58

|I am now copying this code onto my clipboard and pasting it over the existing code in the '''IDE workspace'''.  

| 06:11

|The next step is to '''run''' our project.

| 06:14

| To '''run''' any project on the Netbeans IDE, there are 3 methods.

| 06:20

|The first method is- you can click on the '''project node''' in the '''Projects window''' and choose '''Run''' from the contextual menu.

| 06:29

| Or, you can go to the toolbar and click on the '''Run Project''' button.

| 06:34

|Or, you can also  press the '''F6''' key on your keyboard to run the project.  

| 06:40

| Let me right-click on the '''Project node''' and select the '''Run''' option.

| 06:45

| When you run a '''Java application''', the '''IDE''' '''build'''s and compiles the  '''application code''' and runs the program in the '''output window''' which appears below the '''Workspace'''.

| 07:01

| Let me enter a random number and press '''Enter'''.

| 07:06

| It says if the input is a whole number or a floating point number.

| 07:11

|Now, to the assignment-

| 07:15

|As an extension to the "KeyboardInputReader" project,  

| 07:19

|convert another project i.e. a '''temperatures converter application''' which takes an input temperature,

| 07:27

|converts into Fahrenheit from Celsius and vice-versa.

| 07:31

|And, displays the converted temperature in the output window.

| 07:36

| 07:47

|The program has prompted me to enter the input temperature in the output window.

| 07:52

|Let me enter a sample temperature, -40, in Fahrenheit and it shows me the converted temperature in Celsius.
