Check if a particular value exists in Java TreeMap example
This Java Example shows how to check if TreeMap object contains a particular
value using containsValue method of TreeMap class.

To check whether a particular value exists in TreeMap use
boolean containsValue(Object key) method of TreeMap class.
It returns true if the value is mapped to one or more keys in the
TreeMap otherwise false.

Output would be
