/*
    Stream流中的常用方法concat:用于把流组合到一起
    如果有两个流,希望合并成为一个流,那么可以使用Stream接口的静态方法concat
    static <T> Stream<T> concat(Stream<? extends T> a, Stream<? extends T> b)
 */
public class Test08Stream_concat {
    public static void main(String[] args) {
        // 获取一个Stream流
        String[] arr = {"迪丽热巴", "古力娜扎", "高圆圆", "吴彦祖", "彭于晏"};
        Stream<String> stream = Stream.of(arr);
        // 获取Stream流
        String[] arr01 = {"迪丽热巴", "古力娜扎", "高圆圆", "吴彦祖", "彭于晏"};
        Stream<String> stream01 = Stream.of(arr);

        Stream<String> stream02 = Stream.concat(stream, stream01); // concat只能组合两个流
        stream02.forEach(name -> System.out.println(name));
    }
