Consider an application that must select dynamically an encryption algorithm based on security requirements and computing time constraints. Which design pattern would you select? Draw a UML class diagram depicting the classes in the pattern and justify your choice.

The problem gives the circumstance where an individual needs to create a villain for a video game. I need help creating a villain class UML (Unified Modeling Language). **java**

Your task will be to create a simple text-based simulation that inherits from a pre-existing World class. You must use the World.h provided as a starting point for your code. At least one object in your solution should meaningfully inherit from this class. DO NOT MODIFY THE WORLD CLASS in any way. Note that the World class is abstract and there are a few pure virtual functions for you to implement in your object that inherits from the world. Namely, you will need to implement: void PrintGrid() - This function should print the grid (10 by 10 char array) to standard out. void UpdateGrid() - This function should update your characters' positions on the grid void initGrid() - This function should set your grid up (implement your "starting conditions" here) The scenarios that you will simulate will be confined to a 10x10 grid (defined in the World class as grid) and be subject to at least 10 distinct rules. In addition, there must be at least 2 different objects or “characters”…

When implementing the Comparable interface, what are the best practices for handling objects with multiple attributes that contribute to their natural order?
