+15.Stream流中的常用方法_filter
+Stream<T> filter(Predicate predicate) 返回由与此给定谓词匹配的此流的元素组成的流。
+
+知识点回顾:Predicate:对指定的数据进行筛选判断,符合条件的就返回true,反之
+         boolean test(T t) ---->对应的lambda表达式:t->{return ...}
+
+filter方法的执行原理:
+	它会将stream流 中的每个元素作为以上lambda的参数执行方法体中的代码,如果返回true的数据会保留在新的Stream流中如果返回false那么就筛选掉
+ */
+//需求：将整数 > 6的元素保留，其他的不要
+public class FilterDemo19 {
+    public static void main(String[] args) {
+        //获取流
+        Stream<Integer> stream = Stream.of(1, 100, 2, 88, 11, 5);
+        //过滤流中的元素
+        stream.filter(i -> i > 6).forEach(i-> System.out.println(i));
+    }
