Sherin,
I compiled the prog & I got the following o/p.

Kor finally
Exception in thread "main" java.lang.NullPointerException
at Unchecked1.metod1(Unchecked1.java:36)
at Unchecked1.method(Unchecked1.java:25)
at Unchecked1.main(Unchecked1.java:20)
The finally will always be executed, except exiting the JVM.

Hi sheri!
Your main method is empty, it doesn't call method().
Put smth like this:
class Unchecked1{
public static void main(String[]args){
new Unchecked1().method();
}

[Carl Trusiak]

public static void main(String[]args){
}

Notice close, main doesn't call any methods or create any objects. This is why you get nothing output.
If main had the lines

Unchecked1 uc1 = new Unchecked1(); //needed because metod() isn't static
uc1.method();

Then the answer would be D.
The exception is throw so no code after the line causing the exception and before the catch is executed. It isn't caught so no code in a catch or outside the finally (before or after) is execute. The finally always gets executed (except in System,exit(0)) This contians the only output.

sherin,
The answer c is correct 'cause the main is empty! There is no call to method() so, there is no try, no catch and no finally
Hope that cleared your doubt.
Shubhangi.
