多选题 Given:
2. interface Gadget {
3. int patent = 12345;
4. Gadget doStuff();
5. }
6. public class TimeMachine implements Gadget {
7. int patent = 34567;
8. public static void main(String[] args) {
9. new TimeMachine().doStuff();
10. }
11. TimeMachine doStuff() {
12. System.out.println( ++patent);
13. return new TimeMachine();
14. } }
If javac is invoked twice:
javac -source 1.4 TimeMachine.Java
javac TimeMachine. java
And, if"java TimeMachine" is invoked whenever TimeMachine compiles, what is the result?
