Examination of Object-Oriented Programming
2009/06/15, NTUCS&IE
1. As we know, abstract classes cannot be instantiated. Can abstract classes
have constructors? Explain your reason briefly (at most 5 lines).
[5%+10%]
2. A way to create a thread is to declare a new class, say MyThread, that
extends class Thread.
Class MyThread then overrides the run() method. For example,
class MyThread extends Thread {
public void run() {
// the code of the new thread
}
}
The following code would then create a thread and start it running.
new MyThread().start();
If you forget to override the run() method, what will happen?
Explain your reason briefly (at most 5 lines).
[5%+10%]
3. Is it possible that, at a time, one thread invokes a synchronized method
while the other thread invokes another synchronized method of the same
class? Explain your reason briefly (at most 5 lines).
[5%+10%]
4. Please describe the exception handling mechanism of Java (at most 10 lines).
[15%]
5. Please describe the operation of event-listener programming model
(at most 10 lines).
[15%]
6. Please describe the concept of object-oriented programming in detail
(no line limitation).
[25%]
