# Replace removeAll() with clear()
# Description
Simplifies the code by replacing all occurrences of removeAll() which have the current collection as parameter with clear(). Calling c.removeAll(c) to clear a collection is less clear, susceptible to errors from typos, less efficient and for some collections, might throw a ConcurrentModificationException.
# Benefits
Calling clear() instead of removeAll() makes code more clear and efficient, when at the same time less error prone.
