Which of these helps insert elements at a specific position in a collection?None of themLinkedListSetMap

Break Down the Problem

1. Identify the collections mentioned: LinkedList, Set, Map.
2. Understanding how each collection type functions with respect to inserting elements.

Relevant Concepts

1. LinkedList: A data structure that allows insertion of elements at a specific position.
2. Set: A collection that does not allow duplicate elements and does not maintain a specific order.
3. Map: A collection of key-value pairs where elements can be inserted based on the key, but not at a specific index.

Analysis and Detail

1. LinkedList:

   • Supports insertion at any position, e.g., list.add(index, element) in Java.
   • Provides efficient insertion and deletion compared to arrays.

2. Set:

   • Offers no specific index positions; elements are added with no regard for order.

3. Map:

   • Elements (key-value pairs) are inserted based on keys, but they cannot be placed at specific indices as in an array.

Verify and Summarize

• From the analysis, it is clear that among the listed options, LinkedList is the only collection type that allows inserting elements at a specific position.

Final Answer

LinkedList helps insert elements at a specific position in a collection.
