do while loop

[M Srilatha]

Hi,

Could any one please explain me how the following code works?

01. class Woo {
02. public static void main(String[ ] args) {
03. int w = 1;
04. do while ( w < 1 )
05. System.out.print( "w is " + w );
06. while ( w > 1 ) ;
07. }
08. }

I thought the code will not compile! But it compiles as well as runs

why you thought that this code will not compile? it looks OK. no problem in the code.

Hey thanks for the reply!

I got it now.
This is how it works!

04. do {while ( w < 1 )
05. System.out.print( "w is " + w );}
06. while ( w > 1 ) ;

Before i was thinking that line 4 is a do while loop where its actually do in line4 pairs up with while in line 06. I didnt think in that way.

Anyways now its clear!

I think there will be no output.

The code can be thought of as

int w = 1;
do
{
  while ( w < 1 )
  {
    System.out.print( "w is " + w );
  }
}while ( w > 1 ) ;
