Valentin's Question 38

[Steve Lovelace]

Given this code:

 public class Question38 {
public static void main(String[] args){
while(false);//line 1
if(false);//line 2
do{}while(false);//line 3
for(;false;);//line 4
}
}

the desired answser is:

Compilation error on lines 1 and 4.

However, under 1.4.1-b21 anyway, this code compiles and runs just fine.

Hi Steve,
You are right, the code runs under 1.4.1-b21.
But the thing is that the only authoritative document you should count on is the Java specification and not the different Java implementations. JLS 14.20 Unreachable statements says that the code in question 38 should not compile.
I hope this helps
