Communication Diagram in UML 2.x - which was called Collaboration Diagram in UML 1.x - is interaction diagram which shows interactions between objects and/or parts (represented as lifelines) using sequenced messages in a free-form arrangement.
Communication diagram corresponds (could be converted to/from or replaced by) to simple sequence diagram without structuring mechanisms such as interaction uses and combined fragments.
The UML are behavioral diagram used to describe a set of actions that some systems(s) should or can perform in collaboration with one or more external users of the system. In this case, blood bank management systems.
Class diagram is UML structure diagram which shows structure of the designed system at the level of classes and interfaces, shows their features, constraints and relationships - associations, generalizations, dependencies, etc.Communication diagram (called collaboration diagram in now obsolete UML 1.x) is an interaction diagram which shows interactions between objects and/or parts (represented as UML lifelines) using sequenced messages in a free-form arrangement.So, the major difference is that class diagram shows static structure of the system while communication (collaboration) diagram shows system behavior as sequenced exchange of messages between objects.

To create a UML graphic, first, identify the type of UML diagram you need, such as a class diagram, use case diagram, or sequence diagram. Use UML modeling tools like Lucidchart, Visual Paradigm, or draw.io, which provide templates and shapes specific to UML. Begin by outlining the key components, such as classes, actors, or interactions, and then arrange them according to UML notation standards. Finally, label the components clearly and ensure the relationships between them are accurately represented.

UML 2.4 has 14 different types of diagrams, so you will need to draw not one diagram but several of those. See provided link for online shopping UML examples which provides examples of several common types of UML diagrams.
A collaboration diagram, also known as a communication diagram, is a type of UML (Unified Modeling Language) diagram that illustrates the interactions and relationships between objects in a system. It focuses on the messages exchanged between objects and how they collaborate to achieve a particular functionality. Unlike sequence diagrams that emphasize the time sequence of messages, collaboration diagrams highlight the structural organization of the objects involved, making it easier to visualize their connections and interactions.

UML diagrams are generally produced by electrical engineers and require a thorough knowledge of UML and the Java programming language. Drawing such a diagram is a project given to students in electrical engineering classes.

Class diagram is UML diagram describing static structure of a system on the (lowest) level of classifiers (classes, interfaces, etc.). It shows system's classifiers, their attributes, and the relationships between classifiers.The following nodes and edges are typically drawn in a UML Class diagram:ClassInterfaceInterface RealizationRequired InterfaceAssociationGeneralizationDependency
