Stream流的常用方法-skip和concat

Stream流的常用方法-skip

steam流中的常用方法_skip：用于跳过元素
如果希望跳过前几个元素，可以使用skip方法获取一个截取之后的新流

 public static void main(String[] args) {
        //获取一个Stream流
        String[] arr = {"光头强","熊大","熊二","灰太狼","红太狼"};
        Stream<String> stream = Stream.of(arr);
        //使用skip方法跳过前3个元素
        Stream<String> stream2 = stream.skip(3);
        //遍历stream2流
        stream2.forEach(name-> System.out.println(name));
    }

 

Stream流的常用方法-concat

如果有两个流，希望合并成为一个流，则可以使用 Stream 接口的静态方法 concat

public static void main(String[] args) {
        //创建一个Stream流
        Stream<String> stream1 = Stream.of("吉吉", "毛毛", "翠花", "蹦蹦");
        //获取一个Stream流
        String[] arr = {"光头强","熊大","熊二","灰太狼","红太狼"};
        Stream<String> stream2 = Stream.of(arr);
        //把以上两个流组合为一个流
        Stream<String> concat = Stream.concat(stream1, stream2);
        //遍历concat流
        concat.forEach(name-> System.out.println(name));
    }
