【Java基础】Java8 使用 stream().sorted()对List集合进行排序
一、集合对象定义使用 stream().sorted() 进行排序，需要该类实现 Comparable 接口，该接口只有一个方法需要实现，如下：public int compareTo(T o);有关compareTo方法的实现说明，请参考：Java 关于重写compareTo方法集合对象以学生类（Student）为例，有学生的基本信息，包括：姓名，性别，年龄，身高，生日几项。我的学生类代码如下....

python 中 sorted() 和 list.sort() 的用法
今天用python自带的sorted对一个列表进行排序， 在这里总结一下，只要是可迭代对象都可以用sorted 。 sorted(itrearble, cmp=None, key=None, reverse=False) =号后面是默认值 默认是升序排序的， 如果想让结果降序排列，用reverse=True 最后会将排序的结果放到一个新的列表中， 而不是对iterable本身进行修改。 eg:.....
