#ruby
[1,2,3,4].select{ |x| x.even? }
#python
[x for x in [1,2,3,4] if not x%2]
#or, more norvingly
filter(lambda x: not x%2, [1,2,3,4])
#clojure
(filter #(even? % ) [1 2 3 4])
#but we don't need the wrapper (thanks to the guys in hackernews:)
(filter even? [1 2 3 4])
#scheme
(filter (lambda (x) (even? x)) '(1 2 3 4))
#same here:
(filter even? '(1 2 3 4))
#common lisp
(remove-if-not (lambda (x) (evenp x)) '(1 2 3 4))
#and here:
(remove-if-not 'evenp '(1 2 3 4))
#javascript
[1,2,3,4].filter(function(x){return !(x%2)})
#java
import java.util.ArrayList;
import java.util.Arrays;
public class filter {
public static void main (String [] args)
{
Integer [] a = {1,2,3,4};
System.out.println(
new ArrayList<Integer>(Arrays.asList(a)){{
ArrayList<Integer> clon = (ArrayList<Integer>)this.clone();
for(Integer e : clon){
if(e.intValue()%2 != 0)
this.remove(e);
}
}}
);
}
