Thanks to all of you...
i cleared this exam on 14th of Jan 2008

in the second program when you are coding like this...
parent p=new parent();

castingTest c=new castingTest();

p=c;
c=(castingTest)p;//Line A
then p=c causes reference variable p to refer to object of type castingTest and when you are typecasting in Line A then it checks for the runtime type of the object referred by the reference variable which is of type castingTest therefore there is no problem.....

i also thought the same that it will print A and then throw exception ,but it is not doing the same that is why i asked the question why please make it clear thanks

what will be the output of the following code........
in my machine it is printing A but i think it should throw IllegalThreadStateException but it is not throwing any exception .I run this program so many times on my machine but is is running fine and throwing no exception.


class A extends Thread {
public void run() {
System.out.print("A");
}
}
class B {
public static void main (String[] args) {
A a = new A();
a.start();
try {
a.join();
} catch (InterruptedException ie) {
ie.printStackTrace();
}
a.start(); // 1
}
}
