Get Size of Java LinkedHashMap Example

To get the size of LinkedHashMap use
int size() method of LinkedHashMap class. It returns the number of key value
pairs stored in LinkedHashMap object.
*/

lHashMap.put("1","One");
lHashMap.put("2","Two");

System.out.println("Size of LinkedHashMap after addition : " + lHashMap.size());
//remove one element from LinkedHashMap using remove method
Object obj = lHashMap.remove("2");
System.out.println("Size of LinkedHashMap after removal : " + lHashMap.size());

}
/*
Output would be
Size of LinkedHashMap : 0
Size of LinkedHashMap after addition : 3
Size of LinkedHashMap after removal : 2
