Task
Loops/Foreach
You are encouraged to solve this task according to the task description, using any language you may know.

Loop through and print each element in a collection in order. Use your language's "for each" loop if it has one, otherwise iterate through the collection in order with some other loop.

Java

Works with: Java version 1.5+

<java>Collection<Type> collect; ... for(Type i:collect){

  System.out.println(i);

}</java>

Perl

<perl>foreach $i (@collect) {

  print "$i\n";

}</perl> The keyword for can be used instead of foreach. If a variable ($i) is not given, then $_ is used.

Python

<python>for i in collect:

  print i</python>
