让我们创建字符串Stream：
Stream<String> stream = Stream.of("Bing Bang Theory", "Vampire Diaries", "Game of Thrones", "Homecoming");转换上面的字符串流，并将它们与Collector结合在一起：
final String str = stream.collect(Collectors.joining(" "));以下是将字符串Stream转换为连接它们的示例：
import java.util.stream.Collectors;
import java.util.stream.Stream;
public class Demo {
public static void main(String[] args) {
Stream<String> stream = Stream.of("Bing Bang Theory", "Vampire Diaries", "Game of Thrones", "Homecoming");
final String str = stream.collect(Collectors.joining(" "));
System.out.println("Join result...\n"+str);
}
}输出结果
Join result... Bing Bang Theory Vampire Diaries Game of Thrones Homecoming
