import java.awt.; class Ticker extends Component { public static void main (String [] args) { Ticker t = new Ticker(); / Missing Statements ? */ } } which two of the following statements, inserted independently, could legally be inserted into missing section of this code? boolean test = (Component instanceof t); boolean test = (t instanceof Ticker); boolean test = t.instanceof(Ticker); boolean test = (t instanceof Component);

(2) is correct because class type Ticker is part of the class hierarchy of t; therefore it is a legal use of the instanceof operator. (4) is also correct because Component is part of the hierarchy of t, because Ticker extends Component. (1) is incorrect because the syntax is wrong. A variable (or null) always appears before the instanceof operator, and a type appears after it. (3) is incorrect because the statement is used as a method (t.instanceof(Ticker);), which is illegal.
