please let me know how can i track an abnormal termination of a java program.
i.e. on press of ^C i should be able to catch the termination and display a message.
thanks for any help.

Does the System throw an Exception when you do that or not?
I think that there is also an onTermination routine that you may be able to call as well

The system dosent throw an exception on exit.

i am trying out
1. Runtime.addShutdownHook
2. System.runFinalizersOnExit ()
but it is not helping much.

This worked ...
Stupid me i wasn't overriding run() in the thread i was trying to hook to runtime....
Now it works i got "In Run" on ^c

 
class TestThread extends Thread 
{
public TestThread(){
}

public void run(){
System.out.println("In Run");
}

public static void main(String[] args) 
{
try {
TestThread t = new TestThread();
Runtime.getRuntime().addShutdownHook(t);


while(true){
System.out.println("Hello World!");
}
} catch (RuntimeException e) {
e.printStackTrace();
}
}
}
