A client class has a display method that writes the time represented by its parameter:
/** Outputs time t in the form hrs:mins:secs.
* @param t the time
*/
public void display (Time t)
{
/*
method body */
}
Which of the following are correct replacements for /*
method body */?
I Time T = new Time(h, m, s);
System.out.println(T);
II System.out.println(t.hrs + ":" + t.mins + ":" + t.secs);
III System.out.println(t);
(A) I only
(B) II only
(C) III only
(D) II and III only
(E) I, II, and III
