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?

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 first method to be placed in the stack is also the first method to be processed by the program.
Because the last method to be added to the call stack is the first method to be removed from the call stack.
Because methods can be inserted at any position in the stack.

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