OK, so first lets format your code so that we can read it by using the CODE tags that get created when you click the CODE button under the Add Reply button.

new q().printS1S2(); // 1


Nothing is created on this line, just a compile time error because you need to capitalize the "q".

hi ya after capitalising Q it will compile

here no reference type is declared so no reference type will be created
the answer will be

P.printS1
Q. prints2

the tricky point here is that ... thought instance variable is of Q
but static method of p will be called if the call is made from that class irrespective of instance variable...

hey other ranchers..is i m rt...?


Thanks and Regards, Amit Taneja

What exactly are you saying ?

( that, printS1S2() will call P.printS1() and Q.printS2() ? that's correct )

Can anyone explain in more detail, why is the static method of P is getting called?

static void printS2(){
System.out.println("p.PrintS1");
}
void printS2(){
System.out.println("P. printS2");
}


Can we have same method names printS2(non-static) and printS2(static) ?

I think thats a typo error,
it is
_______________________________
static void printS1(){
System.out.println("p.PrintS1");
}
void printS2(){
System.out.println("P. printS2");
}
________________________________
else we will get a compilation error.
Deepu pls. confirm!!
