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

//create LinkedHashMap object
LinkedHashMap lHashMap = new LinkedHashMap();

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

Output would be
