Definitions:

Factorial Method

A method, often implemented using recursion, to calculate the factorial of a given number, multiplying all positive integers up to that number.

Recursive Void Methods

Recursive void methods are functions that call themselves without returning a value, commonly used for tasks that require repetitive actions or to traverse recursive data structures.

Infinite Recursion

A recursion without a base case, or that never reaches it, leading to a never-ending call stack and eventually a stack overflow error.

Base Case

A condition within recursion that stops the recursion by not making any further calls, preventing infinite recursion.
