Question 5

For this problem, use the Speaker interface, from the Interfaces Example. Recall that the Speaker interface requires any class implementing it to supply a speak method. Suppose that a HashMap collection is defined as:

HashMap col = new HashMap( ); Which loop calls the speak method from each value in the collection col.

Question 5 options:

A	for(Speaker s : col) { col.speak( )); }
B	for(Speaker s : col) { s.speak( ); }
C	for(Speaker s : col.values( )) { s.speak( ); }
D	for(Speaker s : col.values( )) { col.speak( ); }
