Workspaces don't support Java 8+ streams?

I'm trying to use a stream to print out all of the words in the description and it is not working (code below):

import java.util.stream;
//...
blogPost.getDescriptionWords.stream().forEach(System.out::println);

This is the error I'm getting:

Example.java:2: error: cannot find symbol                                                                                                              
import java.util.stream;                                                                                                                               
                ^                                                                                                                                      
  symbol:   class stream                                                                                                                               
  location: package java.util                                                                                                                          
Example.java:10: error: cannot find symbol                                                                                                             
    blogPost.getDescriptionWords().stream().forEach(System.out::println);                                                                              
                                  ^                                                                                                                    
  symbol:   method stream()                                                                                                                            
  location: class String[]                                                                                                                             
2 errors

UPDATE:

I solved the problem. My mistake was treating an array like it was a list. Here is what I should have done:

import java.util.Arrays;
//...
Arrays.stream(blogPost.getDescriptionWords()).forEach(System.out::println);

Also, I didn't need to import "java.util.stream", I guess streams are just in Java by default now.
