Java算法选择排序的相关内容

面试时常常考察的java排序算法--选择排序、冒泡排序、插入排序

注：本文是从java语言角度对三种排序算法进行分析比较。一、选择排序核心思想：依次拿当前元素和其后面的元素比较大小，满足条件就互换值public static int[] shunxu(int[] arr){ int len = arr.length; int temp = 0; for (int ...

java基础算法系列（三）（选择排序的简单优化讲解）

选择排序也是十大排序算法中的一种，他是将整个数组从头到尾全部扫描一遍，然后选择最小的与第一位进行交换，接着再在剩下的元素中进行扫描，直到扫描完毕，最终，得到一个有序数列。这是一种思路非常简单的排序算法。我们先简单的实现一下，代码如下：public static void main(St...

我的Java开发学习之旅------>Java经典排序算法之选择排序

一、算法原理对比数组中前一个元素跟后一个元素的大小，如果后面的元素比前面的元素小则用一个变量k来记住他的位置，接着第二次比较，前面“后一个元素”现变成了“前一个元素”，继续跟他的“后一个元素”进行比较如果后面的元素比他要小则用变量k记住它在数组中的位置(下标)，等到循环结束的时候，我们应该找到...

Java排序算法_选择排序

选择排序的基本操作就是每一趟从待排序的数据元素中选出最小（或最大）的一个元素，顺序放在已排好序的数列的最后，直到全部待排序的数据元素排完。算法不稳定，O(1)的额外的空间，比较的时间复杂度为O(n^2)，交换的时间复杂度为O(n)，并不是自适应的。在大多数情况下都不推荐使用。只有在希望减少交换次数的...
