💡If you are using PlantUML for class diagrams ... turn off the icons

[okkhoy]

If you are using plant UML, the default styling produces diagrams that use icons for various things like class, interface, public etc.,
You can turn off the icons feature to give a more standardized UML diagram using the notations we have learned in the class.

See example below:

The code:

@startuml
abstract class MyTaskList{
  - taskList:ArrayList
  - {static} taskCount: int

  +getTaskCount() : int
}

MyTaskList <|-- DeadlineList
DeadlineList : - deadLine: Date
DeadlineList : getDeadline() : Date
DeadlineList : print()

interface Printable
Printable <|.. DeadlineList
Printable : print()

MyTaskList o-- Task
Task --> "<<Enumeration>> \n TimeUnit"
Task : - taskName: String
Task : + getTaskName()

enum "<<Enumeration>> \n TimeUnit" {
  DAYS
  HOURS
  MINUTES
}

Produces the diagram below. The icons are annotated for quick reference.

You can draw the same diagram using the code below to turn off the icons:

@startuml

hide circle
skinparam classAttributeIconSize 0

class "{abstract} \n MyTaskList"{
  - taskList:ArrayList
  - {static} taskCount: int

  + {static} getTaskCount() : int
}

"{abstract} \n MyTaskList" <|-- DeadlineList
DeadlineList : - deadLine: Date
DeadlineList : getDeadline() : Date
DeadlineList : print()

interface "<<interface>> \n Printable"
"<<interface>> \n Printable" <|.. DeadlineList
"<<interface>> \n Printable" : print()

"{abstract} \n MyTaskList" o-- Task
Task --> "<<Enumeration>> \n TimeUnit"
Task : - taskName: String
Task : + getTaskName()

enum "<<Enumeration>> \n TimeUnit" {
  DAYS
  HOURS
  MINUTES
}

You get this diagram:
