label

[Sireesha Mullapudi]

Hi,

Why this is not giving compile time error.

void crazyLoop()
{
int c = 0;
JACK: while (c < 8)
{
JILL: System.out.println(c);
if (c > 3) break JACK; else c++;
}
}    

here the label is not placed before any loop

Thanks

A label can appear before other statements too. You don't have to put it at the beginning of a loop.

Hi all,

I added JOHN as well:

void crazyLoop() {
int c = 0;
JACK:
while (c < 8) {
JILL:
System.out.println(c);
if (c > 3)
break JACK;
else
[B]c++;[/B]
// not java? ;-)
}
JOHN:
for (int i=5000;i<5003;i++)
System.out.println(i);
 
}

I think, break JACK; is ok, because JACK belongs to the while loop.
both break JILL; and break JOHN; won't compile.

Yours,
Bu.

I tried this code and everything will compile...The compiler will throw an error only when a reference is made to a label with a BREAK statement.
Else the code will compile even though LABEL is placed in NON-LOOP places.
