Creating a project

Netbeans allows

You to have multiple
project open at once.

The main project is the
one that toolbar
operations will affect.


When you choose “Run
project” Netbeans will run
the Main Class it created
during this step


Editing Files

When you choose “Run
project” Netbeans will run
the Main Class it created
during this step

source files under “Source
Packages”. (You can also see
these in the “Files” pane.


Double click a file to edit

Right
-
click on “Source
Pacakges” to add a new file

Running your program

When you choose “Run
project” Netbeans will run
the Main Class it created
during this step


Click to run your
program

(or use the Run
menu to run your
program.)

Debugging


Clicking here will set a “breakpoint”

Breakpoints cause your code to halt at
a specific point for you to examine
variables, the stack, etc… and step line

By line through the code.

Debugging


Once you set a breakpoint you can
debug your program by running the
code in debug mode.

Debugging Tools


Once you set a breakpoint you can
debug your program by running the
code in debug mode.

Keep running to next breakpoint

Step to the next line in this file (call a
method and return)

Step into the method call on this line

Step out of this method
to the caller

View the stack

Check the value of an expression
(using variables from your
program)

Add a variable to watch
window (not shown in this
slide, but will be shown
when you run the
debugger)

Submitting Code


In order to grade your code, you’ll be
submitting a Jar (Java Archive) file with
your compiled classes.


A Jar file is a compressed file (like a Zip
file) to package multiple files together.


You can configure Netbeans to create
the Jar file for you.

Adding source to a Netbeans Jar


In Netbeans to include your source code:


Right click on your project name (in the projects window)


Select properties


Select Build
-
>Packaging


Remove everything in the "Exclude from Jar" texfield.


Click ok.


When you build the software the Jar file created in
<<project name>>/dist/<<project
name>>.jar

will include the source and compiled Java classes. This is the file to turn
in.

Other Notes


The “windows” menu has many other optional
windows you can open.


Right
-
clicking on a keyword/method/variable
name will give you options to see where it is
used or any documentation about it


There are many other things you can do with
Netbeans. See the tutorials on the class
website or just view the help in Netbeans!
