sample on illegal use of labeled continue and break

[Denise Advincula]

(Sorry I forgot to quote my source. Anyway, I'm posting it now. )

This is from Chapter 5 (p. 344) of the K&B Book:

Labeled continue and break statements must be inside the loop that has the same label name; otherwise, the code will not compile.

I'm a little lost on this statement. Can anyone give a sample regarding the statement? I'm trying to make my sample code not compile but it compiles fine if I use two different labels - outer and inner.

This program is an exercise from the same page, modified a little for my own experimentation.

    
public class LabelLoops {
 public static void main(String[] args) {
 
 int age = 16;

 outer: 
  for (;age <= 21; age++) {
    if (age == 16) {
System.out.println("Get driver's license.");
int remainder = age%6;
   inner:
     while (remainder > 1) {
if (remainder == 3) {
   System.out.println("breaking inner");
   break inner;
} else if (remainder == 2) {
   System.out.println("breaking outer");
   break outer;
} else {
   remainder--;
        }
     } // end of inner while
   continue outer;
}
else if (age == 13) {
   System.out.println("unlucky number!");
   break outer;
        } else {
   System.out.println("not 16");
}
 } // end outer
 
 } // end main method
} // end class

Thank you very much in advance!

I think they mean something like this:

    
public class LabelLoops {
public static void main(String[] args) {
 
int age = 16;

outer: 
  for (;age <= 21; age++) 
    {
    if (age == 16) 
      {
      inner:
while (remainder > 1) 
          {
          } 
continue outer;
      }
    else
      {
      continue inner;//HERE!!!
      }

 } // end outer
 } // end main method
} // end class

Note that my "continue inner" is outside of the loop defined by the label "inner".
