Puzzling How to Start with Java Netbeans?? Here is the simple tutorial to get started.

1. Shrey Goswami

2. 
What is an IDE?
IDE(Integrated Development Environment) is a programming environment
integrated into a software application that provides a GUI builder, a text or code
editor, a compiler and/or interpreter and a debugger. Visual Studio,Netbeans
and DreamWeaver are all examples of IDEs.

What is java?
java is a object oriented programming language which enables you to create
applications.

3. 

Install JAVA JDK.
Install Netbeans IDE.

6. 
Navigate to File>New Project.

7. Select java in categories and java Applications
in projects.


8. 
Give project name and uncheck create main
class and click Finish.

9. 

You can finally see Your Project in Projects.
In next step, we will create jFrame in it.

11. 

A jFrame Form acts as a container to place other components
like the button,text field and text area etc.
We can create as many forms we want in a Netbeans Project.
A jFrame containing jLabel,
jTextField and jButton.

12. 
To Create a new jFrame click project name in projects and
right click>New>jframe Form..

13. 
To Create a new jFrame click project name in projects and
right click>New>jframe Form.. And then dialog will open
where you have to give name and click on Finish.

14. 

Now your jFrame is created and now you can add components
like Label,Button,TextField etc.
You can see The jFrame is indicated with red indicator in
Project Folder as well as in Design view.

15. 

Now you can add swing components from Palette by draging
on to the design view and arranging according to your idea.
The Palette is indicated with red border.

16. 

Now I have added jlabel,jTextField and Button to the jFrame.
The jTextField is indicated with Red indicator,jButton with
Blue and jlabel with brown indicator.

17. 

As we have now added the components we can edit the
variable name,text of the components by just selecting them
in the jFrame and right click.
As you can see we can edit the text,change variable
name,properties and so on.

18. 


Now as a example we can make a application where user will enter the name
in jTextField and will get the name back in jLabel after clicking on the
jButton.
To achieve it we have already designed the layout but have to add
functionality by adding code in the jButton as all the task will be done after
clicking the button.
To add Code double click on button and you will be switched automatically
to Source Code.

19. 
Adding the Following code written in Red Block.

20. 





Before you complete, check the component names as it may be different in
your and my case.
In My Case: jLabel1,jTextField1.
You can change the component name by going to Design and selecting
component then right click and navigate to change variable name.
Now its done, and you can run it by holding Shift key and F6 together.
Wait and the Application will run like the screenshot below.
Just test it by Typing your name and clicking “CLICK ME”. You should get the
text you written in jLabel.

21. 
Thats All done from the Introduction. In Next Slide you will learn about
different Components of Java like jLabel,jTextField etc that we used in this
example.
