Answers for "java linkedlist"

java linked list functions

import java.util.LinkedList;
LinkedList<Integer> myList = new LinkedList<Integer>();
myList.add(0);
myList.remove(0);//Remove at index 0
myList.size();
myList.get(0);//Return element at index 0

linkedhashmap in java

LinkedHashMap is same as HasHMap just additionally maintains the insertion order.
