Question

Q1. Match the Interface with its most efficient implementation.

Map:

TreeMap, HashMap, EnumMap, TreeSet, HashSet, EnumSet, ListMap, or ListSet?

Set:

TreeMap, HashMap, EnumMap, TreeSet, HashSet, EnumSet, ListMap, or ListSet?

Set (of enumeration types)

TreeMap, HashMap, EnumMap, TreeSet, HashSet, EnumSet, ListMap, or ListSet?

SortedSet

TreeMap, HashMap, EnumMap, TreeSet, HashSet, EnumSet, ListMap, or ListSet?

Q2. Why is the program call stack best implemented with a stack data structure?

Because the order that methods are added to the call stack is not important.

Because the first method to be placed in the stack is also the first method to be processed by the program.

Question 1)

Answer:

Map: tree map ,as it will store data in tree like manner which will be easier to retrieve.

Set: TreeSet ,as it will store data in tree like manner which will be easier to retrieve.

Set (of enumeration types): EnumSet ,as it is an interface to store enumerated data efficiently

SortedSet: Tree set ,it will store data in tree like manner which will be easier to retrieve.

Question 2)

Answer:

Because the last method to be added to the call stack is the first method to be removed from the call stack.
