# 概述 #

Java Stream API可以使代码变得简洁，也就是在Java中引入函数式编程（函数式编程你可能会以为是某种数据结构，但非如此，它只是一种数据源的视图，数据源可以是数组、java容器（包括List、ArrayList、Vector及map、HashTable、HashMap、HashSet，也就是集合啦）、I/O或channel等）的概念，这也就是为什么JDK1.8会引入此接口的原因。

## Stream ##

Stream是为了方便操作集合而设计的，用它可以把集合的一些复杂过程简便，比如遍历集合取元素等，但要注意的是它不会对数据源背后的数据进行修改（也就是说你要把结果放在新的对象中），还具有懒惰性（也就是不会立即执行，到你需要结果时才执行），并且只能“消费一次”（也就是一次性使用，想要继续使用就要重新弄一个Stream），它常宇lambda表达式一起使用。

### lambda表达式 ###

这个表达式只能出现在，只有一个方法的接口的实现方法中。

> 格式：
> 
> ()->\{\} //无参时前面带上括号，后面花括号里面写你要实现接口的方法内部的内容，当只有一句话时可以省略花括号
> 
> (a,b)->\{\} //有参时里面写上参数，有多少个写多少个，用逗号分开，后面的如上一样
> 
> 对象::方法名 //如：System.out::println
> 
> 类名::静态方法名 //如：有一个类名叫M，它里面有一个静态方法a，那么可以替换为：M::a
> 
> 类名::new //() -> new Student()，可以替换为：Student::new
> 
> //我比较习惯用最上面两种格式

### Stream常用方法 ###

> 1.  Stream<T> filter(Predicate<? super T> predicate) //过滤器，过滤你不需要的数据，操作过后元素个数改变，Predicate 断言接口
> 2.  <R,A> R collect(Collector<? super T,A,R> collector) //用来收集结果的，参数用到`Collector`流
> 3.  Stream<T> distinct() //去掉重复元素
> 4.  <R> Stream<R> map(Function<? super T,? extends R> mapper) //就是对每个元素按照某种操作进行转换，操作过后元素个数不变，Function 函数接口
> 5.  void forEach(Consumer<? super T> action) //用来遍历，消费接口
> 6.  long count() //计算流的个数
> 7.  Stream<T> limit(long maxSize) //限制流的个数，常与forEach一起使用，可以限制遍历的个数
> 8.  Stream<T> sorted(Comparator<? super T> comparator) //用来排序的，参数是比较器，可以自定义排序内容
> 9.  Stream<T> sorted() //会按照自然排序为其排序，如果对于有序的流，排序是稳定的，无序流不稳定性，就不保证了
> 10. Optional<T> max(Comparator<? super T> comparator) //取出最大值Optional表示最大元素，如果为空Optional就为空
> 11. Optional<T> min(Comparator<? super T> comparator) //取出最小值，Optional表示最小元素，如果为空Optional就为空
> 12. <R> Stream<R> flatMap(Function<? super T,? extends Stream<? extends R>> mapper)//把原*stream*中的所有元素都"摊平"组成一组

一写常用接口的及lambda表达式

> 1.Predicate 断言接口
> 
> 对应的lambda 一个参数，返回结果是boolean  
> (a) -> \{ return true|false; \}
> 
> 2. Function 函数接口
> 
> 对应的lambda 一个参数，一个返回结果，参数和返回结果的类型可以不一样；(a) -> \{ 根据a返回结果 \}
> 
> 3. BiPredicate 双参数断言
> 
> 对应的lambda 两个参数，返回结果是boolean  
> (a, b) -> \{ return true|false; \}
> 
> 4. BiFunction 双参数函数接口
> 
> 两个参数，一个结果  
> (a, b) -> \{ 根据ab返回一个结果\}
> 
> 5. Consumer 消费接口
> 
> 一个参数 没有结果  
> (a) -> \{ 不需要return \}
> 
> 6. BiConsumer 双参数消费接口
> 
> 两个参数，没有结果；(a,b)->\{ 不需要return\}
> 
> 7. Supplier 生产者接口
> 
> 没有参数，返回一个结果  
> () -> \{return 结果\}

### 代码演示 ###

1、常用方法的使用

import java.io.Serializable;
    import java.util.*;
    import java.util.stream.Collectors;
    import java.util.stream.Stream;
    
    import static java.util.Arrays.stream;
    
    public class StreamTest {
        public static void main(String[] args) {
            //Arrays.asList可以把里面的数据放到List集合中
            List<Integer> list = Arrays.asList(3, 4, 8, 6, 8, 1, 5);
            //把集合变为流，调用流的方法，这里调用了filter(过滤器)和map以及collect方法，filter方法用来过滤不满足你要求的数据，map对流中的数据进行操作，最后用collect收集结果放入新对象中
            //也就是说，先用filter把大于3的数据找出来，在用map操作里面的数据（大于3的数据），把里面的数据都乘上2
            List<Integer> collect = list.stream().filter((i) -> i > 3).map((s) -> s * 2).collect(Collectors.toList());
            System.out.println(collect);
            //先用filter把大于3的数据找出来，在用map操作里面的数据（大于3的数据），把里面的数据都乘上2，然后用distinct把重复的数据去掉（只保留一个该重复的数据）
            List<Integer> distinct = list.stream().filter((i) -> i > 3).map((s) -> s * 2).distinct().collect(Collectors.toList());
            System.out.println(distinct);
            //遍历流中的三个元素，limit为限制读取流的个数，ForEach是用遍历的
            list.stream().limit(3).forEach((i)-> System.out.print(i+" "));
            //可以写为以下形式，对象名::方法名
            list.stream().limit(3).forEach(System.out::print);
            System.out.println("");
            //计算流中的元素，你会发现结果为七，因为Sream不会改变其数据源背后的数据，在过程中改变的数据会由新的对象来接收，因此不会改变数据源
            long count = list.stream().count();
            System.out.println(count);
            //取出大于三并且乘以2后的最大值
            Optional<Integer> max = list.stream().filter((i) -> i > 3).map((s) -> s * 2).max(new Comparator<Integer>() {
                @Override
                public int compare(Integer i1, Integer i2) {
                    return i1 - i2;
                }
            });
            //以上的式子可以写为以下，因为Comparator（比较器）它里面只有一个方法，它的方法有两个参数，因此括号里2个参数，后面一个句子因此可以把return和分号省略
            //Optional<Integer> max = list.stream().filter((i) -> i > 3).map((s) -> s * 2).max((i1,i2)->i1-i2);
            System.out.println(max);
            //把数组存入集合中
            List<int[]> ints = Arrays.asList(new int[]{2, 4, 5}, new int[]{1, 3, 4});
            //把集合中的数组都放入一个流中使他们变为一个整体，遍历时只需遍历一次，flatMapToInt是用来使整数摊平的，也就是使多个不同对象中的整数，聚合成一个对象，这样遍历时只需要遍历这个对象
            ints.stream().flatMapToInt(s -> stream(s)).forEach(s-> System.out.print(s+" "));
            System.out.println("");
            //用Stream.of把数据存入流中
            Stream<List<? extends Serializable>> stream = Stream.of(Arrays.asList("zhangsan", 10), Arrays.asList("lisi", 20));
            //用flatMap可以使在不同的对象中的数据存入同一流中，然后遍历，这样就只要遍历一次，而不需要像以前一样遍历对象，如学生类放入集合中，你要先遍历集合然后在里面嵌套遍历学生类，这样写会把代码变得很杂
            stream.flatMap(s->s.stream()).forEach(s-> System.out.print(s+" "));
    
        }
    }

结果

[8, 16, 12, 16, 10]
    [8, 16, 12, 10]
    3 4 8 348
    7
    Optional[16]
    2 4 5 1 3 4 
    zhangsan 10 lisi 20

注意：如果你使用了filter和map等中间操作（concat() 、distinct() 、filter() 、flatMap() 、limit() 、map() 、peek() 、skip() 、sorted() 、parallel()、 sequential() 、unordered()），没有使用结束操作（allMatch() 、anyMatch() 、collect() 、count() 、findAny() 、findFirst()  
forEach()、 forEachOrdered()、 max()、 min()、 noneMatch() 、reduce() 、toArray()），你会发现你写要的结果没有得到，这是因为Stream具有懒惰性，也就是说代码不会立马执行（当你执行中间操作是），等到你真正需要结果的时候才会执行（当你执行结束操作时），这也就是流水线（Pipeline）思想。

以下是举例说明流水线思想图

2、读取heroes.txt的数据，并对数据做如下操作

1. 找到武将中武力前三的hero对象, 并算出每组人数
         2. 按出生地分组
         3. 找出寿命前三的武将

把读取到的数据存入对象（WuJiang）中，方便后面对它进行操作

public class WuJiang {
        private String name;
        private String sex;
        private String location;
        private int birth;
        private int death;
        private int power;
        private int num;
    
        @Override
        public String toString() {
            return "WuJiang{" +
                    "num='" + num + '\'' +
                    ", name='" + name + '\'' +
                    ", location='" + location + '\'' +
                    ", sex=" + sex +
                    ", birth=" + birth +
                    ", death=" + death +
                    ", power=" + power +
                    '}';
        }
    
        public WuJiang(int num, String name, String location, String sex, int birth, int death, int power ) {
            this.num = num;
            this.name = name;
            this.location = location;
            this.sex = sex;
            this.birth = birth;
            this.death = death;
            this.power = power;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public String getSex() {
            return sex;
        }
    
        public void setSex(String sex) {
            this.sex = sex;
        }
    
        public String getLocation() {
            return location;
        }
    
        public void setLocation(String location) {
            this.location = location;
        }
    
        public int getBirth() {
            return birth;
        }
    
        public void setBirth(int birth) {
            this.birth = birth;
        }
    
        public int getDeath() {
            return death;
        }
    
        public void setDeath(int death) {
            this.death = death;
        }
    
        public int getPower() {
            return power;
        }
    
        public void setPower(int power) {
            this.power = power;
        }
    
        public int getNum() {
            return num;
        }
    
        public void setNum(int num) {
            this.num = num;
        }
    }
