Given:
10.abstract public class Employee {
11.protected abstract double getSalesAmount();
12.public double getCommision() {
13.return getSalesAmount() * 0.15;
14.}
15.}
16.class Sales extends Employee {
17.// insert method here
18.}
Which two methods, inserted independently at line 17, correctly complete the Sales class? (Choose two.)

16.17.
if ((x == 4) && !b2 )
18.System.out.print("1 ");
19.System.out.print("2 ");
20.if ((b2 = true) && b1 )
21.System.out.print("3 ");

11.public class Mountain extends Rock {
12.Mountain() {
13.super("granite ");
14.new Rock("granite ");
15.}

• C.df = DateFormat.getFormat();
• D.df = date.getFormat();
• E.df = new DateFormat();
