From the Object menu, select New -> Class
Shortcut: Ctrl-L or Click the Class icon on the toolbar.

A new component appears in the class diagram window named "Class1".
Type in the name for the class you are creating, e.g. Customer.

From the Object menu, select new -> Attribute
Shortcut: Ctrl-A

Type in the name and type for the attribute, e.g. name: String
Observe the java code generated automatically in the editor pane.  Cool!
Note: a minus sign means "private", a plus sign means "public".

From the Object menu, select new -> Operation
Shortcut: Ctrl-O

Type in the name and return type for the operation, e.g. verifyPIN: boolean
Observe the java code generated automatically in the editor pane.

In the editor pane, type in the source code for the body of the method: return true;
 

Tip: Under the Options menu, turn off "Recognize Java Beans."
 
 

Creating associations between classes

Create an Account class, with attribute balance and operation debit.

Click on the Customer class and add a new attribute: Checking: Account
Observe the diagram places an arrow between Customer and Account.
 

Compiling your application

Create a class that contains a main method.
From the Tools menu, select Make Project.
Look in the messages pane to verify make was successful.

From the Tools menu, select Run/Debug -> Run.
Verify the arguments and parameters dialog box specifies the correct main class.
Look in the messages pane to see output to console.
