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
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.
- Continuous allocation:
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.
