(UML) What's the different between usage dependency-arrow and Implement arrow?

I am really confused lets say:

public interface Foo{...}
public class Bar implements Foo{...}

then UML design should look like [ Bar ] --|> [ Interface Foo ]

  • --|> = implements

But what the hell is Usage Dependency? and the arrow looks like -->

Can someone give me a code example how Usage Dependency looks like? (don't give me complicated codes :joy: :wink: )

you already have usage dependency :)

Bar is dependant of Foo

Hi Chris! You cant just draw arrow like this [ Bar ] --> [ Interface Foo ] that mean something ells..:yum:
