  List<String> stringList = Arrays.asList("1","2","3","4","5");

 stringList.stream().mapToInt(n-> Integer.parseInt(n)).    
 filter(n-> n%2 == 0).forEach(System.out::println);

This pops up in the compiler's screen:

n cannot be resolved to a variable n cannot be resolved to a variable Syntax error on token "-", -- expected n cannot be resolved to a variable Syntax error on tokens, delete these tokens println cannot be resolved to a variable

There is nothing wrong with the code, so perhaps you are not compiling with Java 8. – Eran Oct 24 '17 at 18:48
@Eran Indeed. Thank you for the question edit. – davidxxx Oct 24 '17 at 18:49
Sounds like it if `->` is not recognized and `println` after `::` as well. – luk2302 Oct 24 '17 at 18:49
In order to have Java 8 should I have the latest Eclipse ? Because I am using Linux Ubuntu for the moment and it is a 2012 version .How can I switch to java 8 ? – Redion Xhepa Oct 24 '17 at 18:49
