which two of the following statements, inserted independently, could legally be inserted into missing section of this code?
1. boolean test = (Component instanceof t);
2. boolean test = (t instanceof Ticker);
3. boolean test = t.instanceof(Ticker);
4. 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.
