下面是一个使用Arrays.sort()对整数数组进行倒序排序的示例: importjava.util.Arrays;importjava.util.Comparator;publicclassMain{publicstaticvoidmain(String[]args){Integer[]numbers={5,2,9,1,7};// 使用Comparator进行倒序排序Arrays.sort(numbers,newComparator<Integer>(){@Overridepublicintcompare(Integero1,I...
/* * Every element from adjoining part plays the role * of sentinel, therefore this allows us to avoid the * left range check on each iteration. Moreover, we use * the more optimized algorithm, so called pair insertion * sort, which is faster (in the context of Quicksort) * than tra...
1、Arrays.sort(int[] a) 这种形式是对一个数组的所有元素进行排序,并且是按从小到大的顺序。 举例如下(点“+”可查看代码): importjava.util.Arrays; publicclassMain {4publicstaticvoid main(String[] args) {int[] a = {9, 8, 7, 2, 3, 4, 1, 0, 6, 5}; Arrays.sort(a);for(inti = ...
