无效的比较器(Invalid comparator) 正确的比较器 sort的严格弱排序的性质 我在给结构体数组排序的时候,自定义了sort函数的排序法则,我的结构体如下定义: structscore { inta, b, c;//语数英 intsum;//总分 intnum;//学号 }; 排序标准: 首先按照总分排序 总分相同的情况下按照语文成绩a排序 再相同的情况下,...
(2)Collections.sort(list, Comparator);可以传入一个比较器,也可以将比较器反转 packagecn.xm.exam.test;importjava.util.ArrayList;importjava.util.Collections;importjava.util.Comparator;importjava.util.List;publicclassTest2 {publicstaticvoidmain(String[] args) { List<Integer> list =newArrayList<>(); ...
This function just helps you figure out the order of x and y for any arbitrary x and y. Note that your comparator must follow some basic properties, else you won't get the expected results. Link to very helpful blog → Reply SNX03 ...
最后返回一个与原数组顺序不变的数组C<0: comparator比较器会认为任意两个a和b都是错误排序，需要交换...

One function is the comparator that compares two values and yields an indication of the sort order, the other function is a key-extraction function that runs on each element of the collection to be sorted and extracts a value that is passed to the comparator....
