What is the name of the implicit variable in a java while loop?

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...

Answer 2

There is no such concept in Java.

In Groovy, at least you get an it variable set on the functional methods.

myList = [1,2,3];
myList.each {
   println it
}

or to read a file, like in your example...

new File('test.txt').eachLine {
   println it
}
