Get Size of Java LinkedHashSet Example
This Java Example shows how to get the size or nubmer of elements stored in
Java LinkedHashSet object using size method.

To get the size of LinkedHashSet use
int size() method of LinkedHashSet class. It returns the number of elements
stored in LinkedHashSet object.
*/

//add elements to LinkedHashSet object
lhashSet.add(new Integer("1"));
lhashSet.add(new Integer("2"));
lhashSet.add(new Integer("3"));
System.out.println("Size of LinkedHashSet after addition : " + lhashSet.size());
//remove one element from LinkedHashSet using remove method
lhashSet.remove(new Integer("1"));
System.out.println("Size of LinkedHashSet after removal : " + lhashSet.size());
}
}
/*
Output would be
Size of LinkedHashSet : 0
Size of LinkedHashSet after addition : 3
Size of LinkedHashSet after removal : 2
