I am trying to draw class diagrams for my classes.<br />

I have one interface called IFetchContentSource. It has the following details<br />

getContentByLocation(Array<wbr />list location, String source_object_type, ArrayList source_metadata_fields, ArrayList staging_metadata_fields): ContentAndMetadata []<br />

The return type of one of the methods of this Interface is ContentAndMetadata, which is defined as<br />
<br />
File contentFile<br />
HashMap metadata_fields_values: String staging_metadata_fields, String source_metadata_values<br />

Please let me know how the relation between these two classes be specified using class diagrams. Will there be just an arrow from IFetchContentSource to ContentAndMetadata

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Visio is a diagramming and vector graphics application that is part of the Microsoft Office family that allows the user to create diagrams for organizational and planning purposes. The Premium edition has additional templates for more advanced diagrams and layouts, as well as capabilities intended to make it easy for users to connect their diagrams to data sources and to display their data graphically, as well as intelligent rules, validation, subprocess (diagram breakdown). one-step connectivity with Excel data, information rights management (IRM) protection for Visio files, modernized shapes for office layout, detailed shapes for site and floor plans, modern shapes for home plans, and IEEE compliant shapes for electrical diagrams.
