Check if a particular element exists in Java LinkedHashSet Example

LinkedHashSet using contains method.

To check whether a particular value exists in LinkedHashSet use
boolean contains(Object value) method of LinkedHashSet class.
It returns true if the LinkedHashSet contains the value, otherwise false.
