what is the unreachable code?
i tried the following code:
if(false){int i=0;}
it is compiled successful
but when i tried the following code individually:
for(int i=0;false;i++){int j=0;}
while(false){int i=0;}
it can not be compiled!
so what's the unreachable code?

Please have a look at JLS 14.20 Unreachable Statements
In a nutshell, if(false) is tolerated to allow conditional compilation. for(;false ; ) and while(false) are not allowed by the compiler.
