Question

In Perl you can write something like

while(!eof){  
    doSomething(x,y);  
    print $_;  
}

and the second statement prints out the iteration the loop is up to using $_, the name of the invisible variable Perl uses to iterate through the loop. What is the name of that variable in Java?

I realise that you can accomplish the same thing by declaring a variable outside the loop and incrementing it, but this way is definitely more elegant if anyone knows how to do it.

Answer 1

There’s no implicit variable in Java as in Perl. You just have to be more explicit in Java…
