If you're building a system for online voting where each vote is unique, but the order in which votes are cast doesn't matter, which interface would be the best pick?

• List Interface

• Set Interface

• Queue Interface

• Map Interface

When designing an application to manage a restaurant's waiting list where customers are served based on their arrival, which interface would be best suited?

• List Interface

• Set Interface

• Queue Interface

• Map Interface

What distinguishes the LinkedHashSet class from the HashSet class in the Java Collections framework?

• LinkedHashSet maintains insertion order

• LinkedHashSet allows duplicate values

• LinkedHashSet uses a tree structure for storage

• LinkedHashSet provides faster access times

If you need a data structure that can be accessed and modified by multiple threads safely, which class would you select?

• ArrayList Class

• Vector Class

• LinkedList Class

• HashSet Class

When you need a resizable array with efficient random access, which class is the most relevant choice?

• LinkedList Class

• ArrayList Class

• HashSet Class

• TreeSet Class

If you need a collection that ensures a first-in-first-out (FIFO) behavior, which interface would be the best fit?

• Set Interface

• List Interface

• Map Interface

• Queue Interface

Which interface ensures element order based on their natural ordering or by a provided comparator?

• Set Interface

• List Interface

• SortedSet Interface

• Queue Interface

When designing a data structure that allows duplicates, maintains insertion order, and provides random access, which interface is the most suitable?

• Set Interface

• LinkedHashSet Class

• List Interface

• TreeSet Class

Which interface is best suited to represent a group of objects as a single unit?

• List Interface

• Set Interface

• Collection Interface

• Queue Interface

What's the primary advantage of using the SortedSet Interface over the standard Set Interface?

• It allows duplicates

• It processes items in a FIFO manner

• It sorts items based on their natural order or a defined comparator

• It allows random access
