Remove all values from Java TreeMap example
This Java Example shows how to remove all values from TreeMap object or empty
TreeMap or clear TreeMap using clear method.

To remove all values or clear TreeMap use
void clear method() of TreeMap class. Clear method removes all
key value pairs contained in TreeMap.

Output would be
