Lesson 47

//QUESTION 1
Map obj = new HashMap();
obj.put("Sally", "blue");

//QUESTION 2
// HashMap and TreeMap

//QUESTION 3
Iterator itr = mp.keySet().iterator();

//QUESTION 4
Map hoover = new HashMap();

//QUESTION 5
// Maps have two values associated with each other (a key and its value).

//QUESTION 6
// If the key exists, the value is overridden.

//QUESTION 7
// No because keys are not allowed to repeat.

//QUESTION 8
// You would do so using the .size() command.

//QUESTION 9
System.out.println(tiny.get(obj));
