Get the count of association for a document

[kawin]

I need to get only count of association for a document which is highlighted in the below image.

Is there a way to get only count using Java Webscript?

What class we need to implement to achieve this?

I guess you can use something like the following from Repository JavaScript tier:

document.associations.length

I need to find the count using Java. Is there a way to achieve this using Java?
