1. How to create and access
variables
Become an AnyLogic Expert Step by Step
2. About me
khoi.tran@simbean.com 2
My name is Khoi Tran and I’m living in beautiful Stuttgart, Germany.
As a 12-years expert in the software industry and 6-years expert in
simulation with AnyLogic, I would like to share my experiences
with you on a simple and fast path.
3. Learning subjects
khoi.tran@simbean.com 3
In this example you can learn,
• How to create different kinds of plain variable.
• Normal plain variable
• Static plain variable
• Constant plain variable
• Collection variables
You can see the demo in action first

If you like to know, how I built this model, this presentation may help you.
4. Create different plain variables
khoi.tran@simbean.com 4
Drag & drop all the
variables and rename
them
Create an active object called “PlainVarAO“ and insert the plain variables.
5. Properties of normal plain variable
khoi.tran@simbean.com 5
The name of the plain
variable can be changed, first
character should be lower-
case as Java convension
Like the variable in Java, access
modes are “public“,
“protected“ and “private“.
With “default“ the variable
can be access everywhere in
the model
A variable can be
static or constant
Some simple variable types are
listed as options, but you can
define the plain variable with
arbitrarily object type.For a double type, inital value can be e.g.
1.5, but for a String type, the initial value
must be in quota e.g. „initial value“
6. Access and assign value for an normal
plain variable
khoi.tran@simbean.com 6
Create embedded
object on “main“
active object
Assign and access the variable
of active object “plainVarAO“
in startup code of “main“
active object
7. Properties of static plain variable
khoi.tran@simbean.com 7
Change the name of the plain
variable
Define this plain
variable as a static
plain variable
8. Access and assign value for an static
plain variable
khoi.tran@simbean.com 8
Asign and access the variable
of active object “plainVarAO“
in startup code of “main“
active object
As Java convension, you will get a
warning, if character “p“ of
“plainVarAO“ is lower case.
Character “P“ must be upper case.
As Java convension, you will get a
warning, if character “p“ of
“plainVarAO“ is lower-case.
Character “P“ must be upper-case.
“//“ is marked as comment, if
you want to see the effect of
this line of code, please
uncomment it by removing the
“//“
9. Properties of constant plain variable
khoi.tran@simbean.com 9
Define this plain
variable as a constant
plain variable
Change the name of the plain
variable, as Java convension, all
the characters are upper-case
10. Access and assign value for an constant
plain variable
khoi.tran@simbean.com 10
As a constant plain variable, you can
access its value, but you are not able to
assign any value to it
11. Create different collection variables
khoi.tran@simbean.com 11
Drag & drop all the
collection variables
and rename them
Create an active object called “CollectionVarAO“ and insert the collection variables.
12. Create different collection variables
khoi.tran@simbean.com 12
Choose
„java.util.LinkedList“
for both variable
Element class is
“String“
Choose “Static“
for definition of a
static collection
13. Access and assign collection variables
khoi.tran@simbean.com 13
In each active object
there is a collection and
value can be added
In each active object
there is a collection and
value can be added
Using the for loop for
printing out all the values
in the collection
14. Access and assign static collection variables
khoi.tran@simbean.com 14
For static collection the name
of the class is used, that‘s
why the first character is
upper-case
15. Run the model
khoi.tran@simbean.com
Click on the run button and
choose the simulation
15
1. You can run the model and see the result
2. Try to change or set properties to see some small effects e.g.
1. Add more values to the collection variable.
2. On slide 12, you can try it with different collection classes.
3. You need to restart the model to see the effects
