labeled break and continue

[sachin patel]

Hi all,
can anybody tell me whether it is legel or not to add label to statments other than loops.

HI Sachin
It is illegal In java
You can't use label other then loop and only in for, while, switch loop, in java Continue and break are a spicial loop flow control so you can't use it another place.
Outer:
System.out.println("HELLO"); // 1
While(i <10) { }
Above code will give compile time error.
yeah but you can use it in C anc C++ at any where

you are wrong Himanshu,
the code will compile OK, try it
but it will give a compile error if you try to use the label any where inside the loop

Well what Himanshu was trying to convey was right but the code does compile Himanshu!! The reason is that it is not illegal to label any statement in the program. However when labels are used in conjunction with break or continue they HAVE to refer to loops and not to any statments in the program. Otherwise a compile time error occurs stating 'undefined label'

Hi Rose
In java You can't use label other then loop
means
(1)valid (Just only in starting of loop )
Outer:
while(i <10 ) {.......}
(2)illegal
Outer :
System.out.println("Helo");
while(i<10) {........}
(3)illegal
while(i<10) {
Outer:
System.out.println("Hello");
i++;
}

Hi Sachin,
I just visited the FAQ in JavaRanch. It says that declaration statements cannot be labelled. This was news to me! So you too check it out!
