tricky!!!! tricky!!

[tian Lau]

could someone tell if the tricky stuff like the following will appears in the real test???
public class Test5 {
public static void main (String args []) {
/* This is the start of a comment
if (true) {
Test5 = new test5();
System.out.println("Done the test");
}
/* This is another comment */
System.out.println ("The end");
}
}
What will print out???

[kevin jia]

It is " the end ".

I'm not sure..no variable of type Test5 is being declared in the statement:
Test5 = new Test5();
Will this code compile at all?
Thanks,
Aman

I executed the program and I got 'the end' only. Actually how does 'if (true) or if (false) executed? . Anybody can explain?.
Thanks in advance.

This code will generate a compilation error
Undefined variable : Test5
Class test5 not found

Hi folks,
you have to watch out this code carefully:
/* This is the start of a comment// of course but not finished
if (true) {
Test5 = new test5();
System.out.println("Done the test");
}
/* This is another comment */ // here comes the end
After setting the right comments, you have to make to
changes:
Test5 test5 = new Test5();
After this, xou will see what you expect!

Easy questions like this will NOT appear in the real exam. I am 1000% sure !

IMHO
The only statement outside the comment block is
System.out.println ("The end");
So the main method executes and prints the string literal.

If you put this code in an IDE that displays comments as a different color or in italics will see that all the code before the end comment tag is treated as a comment like it should. Therefore, you are left with "the end".

folks,
after seeing so many comments upon what seemed to be an easy piece of code, i decided to try it out. i cut-pasted the given code, compiled it and ran it and it gave me the output - "The End". so, it should mean that even if you are not instantiating your base class, it will compile and run.
This is the console output that i got.

Actually I think that it treats that whole portion, where the class is instantiated, as a comment so the compiler ignores it & prints 'The end'. But if you close the comment like this, compiler will complain.
public static void main (String args []) {
/* This is the start of a comment */ (Notice this)
if (true) {
Test5 = new Test5();
System.out.println("Done the test");
}
/* This is another comment */
System.out.println ("The end");
}
}

Friends,
Once compiler see '/*' mark he ignores every thing until he see a closing ie '*/' so for the compiler code look as simple as the following
class Test5 {
public static void main(String args[]){
System.out.println("The end");
}
}
I hope this will help everybody
And I agree that it is good question which covers the comments in java lang.
