A list is a collection that _____.

a. associates keys with elements
b. assigns an index to each of its elements
c. is implemented by the JList class
d. none of the above

Expert Solution & Answer

Program Description Answer

A list is a collection that “assigns an index to each element in a list”.

Hence, the correct answer is option “B”.

Explanation of Solution

List:

A list is a collection that stores its element in a location-based order.
Each element in a list is related with an index that matches to its location within the list. That is the first element contains index 0, the second element contains index 1 and so on.
Storage allocation for the elements of a list takes place in two methods such as contiguous allocation and linked allocation.
- Continuous allocation:
  - Array-based lists use this allocation.
  - It assigns storage for consecutive list elements in consecutive memory locations.
- Linked allocation:
  - This allocation does not require consecutive memory locations to store list elements.
  - It uses a pointer to store each element in a list.

Explanation for incorrect options:

A list is a collection that associates index with elements not keys.

Hence, the option “A” is wrong.

“JList” is a type of Java Swing package. It is a component that shows a set of objects and permits the user to choose more than one element from the list.

Hence, the option “C” is wrong.
