Introduction<\/h3>\n

The linked list is one of the most important data structures to learn while preparing for interviews. Having a good grasp of Linked Lists can be a huge plus point in a coding interview.<\/p>\n<\/p>\n

Problem Statement<\/h3>\n

In this problem, we have to convert all the LinkedHashMap values to a List in Java.<\/p>\n

Problem Statement Understanding<\/h3>\n

Let us suppose that we have a LinkedHashMap that has key-value pairs:
\n(1,23), (2,45), (3,67)<\/strong>. <\/p>\n

Now, we have to create a Linked List, which contains all the values of the given LinkedHashMap. So, the resultant list will be: <\/p>\n

\"\"<\/p>\n

If the LinkedHashMap has key-value pairs as:
\n(1,10), (2,20), (3,30), (4,40)<\/strong>.<\/p>\n

Now the resultant linked list which will contain all the values of give LinkedHashMap will be:<\/p>\n

\"\"<\/p>\n

Explanation:<\/strong> The output list contains all the values present in the LinkedHashMap.<\/p>\n

A LinkedHashMap stores key-value pairs, and a List is an ordered collection of elements. Let us have a glance at the approach.<\/p>\n

Approach and Algorithm<\/h3>\n

To convert all the values of a LinkedHashMap to a List in Java, we can use the values() method. The values() is a method of the LinkedHashMap that returns a Collection of all the values in the map object. We can then convert this collection to a List object.<\/p>\n

Syntax – LinkedHashMap.values()<\/strong><\/p>\n
