java.util.stream.Stream

public abstract boolean allMatch(Predicate arg0)//所有为真，返回真
public abstract boolean anyMatch(Predicate arg0)//任一个为真，返回真
public static Builder builder()//流构造器，Stream.Builder<String> builder = Stream.builder();　　builder.add("Production");　　Stream<String> stream = builder.build();
public abstract Object collect(Supplier arg0,BiConsumer arg1,BiConsumer arg2)
public abstract Object collect(Collector arg0)//聚集操作
public static Stream concat(Stream arg0,Stream arg1)//合并两个流
public abstract long count()//数量
public abstract Stream distinct()//去重，元素实现equals和hasCode
public static Stream empty()//返回空的流
public abstract Stream filter(Predicate arg0)//过滤器
public abstract Optional findAny()//随机返回一个，一般是第一个，如果是并行流就不一定是第一个
public abstract Optional findFirst()//返回第一个元素
public abstract Stream flatMap(Function arg0)//把元素拆解成流，所有元素的流形成一条流
public abstract DoubleStream flatMapToDouble(Function arg0)//返回的是double流
public abstract IntStream flatMapToInt(Function arg0)//返回的是int流
public abstract LongStream flatMapToLong(Function arg0)//返回的是long流
public abstract void forEach(Consumer arg0)//遍历
public abstract void forEachOrdered(Consumer arg0)//保持顺序的遍历，并行流中也能保持顺序
public static Stream generate(Supplier arg0)//使用这个工厂无限生成流，可用limit来限制数量，常用来产生数个随机数
public static Stream iterate(Object arg0,UnaryOperator arg1)//无限产生流，把前面的返回值放到下一个参数中，可用limit来限制数量，Stream.iterate(new Student("小明", 22),x->{x.setAge(x.getAge()+2);return x;}).forEach(System.out::println);
public abstract Stream limit(long arg0)//限取几个
public abstract Stream map(Function arg0)//变换成别一种类型

public abstract Optional max(Comparator arg0)//获取最大值
public abstract Optional min(Comparator arg0)//获取最小值
public abstract boolean noneMatch(Predicate arg0)//所有为假，返回真
public static Stream of(Object arg0)//构造中一个流
public static transient Stream of(Object[] arg0)//构造中一个流
public abstract Stream peek(Consumer arg0)//遍历可修改，再返回流
public abstract Optional reduce(BinaryOperator arg0)//例有值ABCD，把AB代入function后得出的结果Z作为下个fucntion的第一个参数，第二个参数为C，即ZC，如此下去，详见：https://blog.csdn.net/icarusliu/article/details/79504602
public abstract Object reduce(Object arg0,BiFunction arg1,BinaryOperator arg2)//arg0为初始参数，充当arg1中的第一个参数，arg2为并行时最终结果的合并
public abstract Object reduce(Object arg0,BinaryOperator arg1)//arg0为初始参数，充当arg1中的第一个参数
public abstract Stream skip(long arg0)//跳过数量
public abstract Stream sorted(Comparator arg0)//排序
public abstract Stream sorted()//排序，元素实现Compareble即可
public abstract Object[] toArray(IntFunction arg0)//转换成数组，参数为产生数组的工厂
public abstract Object[] toArray()//转换成数组
