Let’s dive in and start mastering list sorting in Java! TL;DR: How Do I Sort a List in Java? The simplest way to sort a list in Java is by using theCollections.sort()method. This method sorts the specified list into ascending order, according to the natural ordering of its elements...
具体说来,就是调用filter()方法后立即执行,选出所有以A开头的字符串并放到一个列表list1中,之后让list1传递给mapToInt()方法并立即执行,生成的结果放到list2中,最后遍历list2找出最大的数字作为最终结果。程序的执行流程如如所示: 这样做实现起来非常简单直观,但有两个明显的弊端: ...
