Is there a goto statement in Java?
I'm confused about this. Most of us have been told that there isn't any goto statement in Java.
But I found that it is one of the keywords in Java. Where can it be used? If it can not be used, then why was it included in Java as a keyword?

Will using goto leak variables?
Is it true that goto jumps across bits of code without calling destructors and things?

int x = 0;
goto lol;
}
int main() {
f();
lol:
return 0;
}
Won't x be leaked?
