lambda表达式

//lambda新建线程

Thread t1 = new Thread(() -> System.out.print("heeh"));
t1.start();

//lambda便利

String[] strs = {"bb","aa",  "cc"};
List<String> list = Arrays.asList(strs);
list.forEach(System.out::println);

//lambda排序

String[] sort = {"za","fbb","cc"};

Arrays.sort(strs,(s1,s2)->(s1.compareTo(s2)));

//lambda过滤
