Final answer:
The list of methods in the Frames window in reverse order is known as the call stack or stack trace, which is essential for debugging software and understanding program flow.
Step-by-step explanation:
In the context of the Frames window, a list of methods in the reverse order in which they were called is known as the call stack or stack trace.
This is a common tool used in debugging software to understand the sequence of method calls that led to a certain point in a program's execution.
When a method is called, it is placed on top of the stack, and when it completes, it's removed, revealing the previous method in the stack.
This makes the call stack a valuable resource for tracking the flow of a program, especially when errors occur.
