I have a code like this:
if(condition1)
{
break MyLabel;
}
while(true)
{
//some code here
MyLabel: if(condition2) break;
//more code here
}
and I get this error:
The label MyLabel is missing.
What's wrong?
You can only break to a label that is on a textually enclosing statement. In your example, the label is NOT on a statement that encloses the break
statement.
(For what it is worth, even higher-level languages that support goto
don't allow you to jump into the middle of a loop from the outside. I'm thinking of C ... and older languages like FORTRAN.)
Java allows you to break out, but breaking in is illegal ... and will get you arrested :-)
(Sorry, I couldn't resist it. For those who don't get the joke, a "break in" is when someone enters your house to steal stuff - see "break and enter" ... )
You can't use labels as goto in that general way.
Use labels if you want to goto a higher level of nested code.
for example
l1: while
l2: while
l3: while
break l1
l4: while
