代码如下:
public class BinaryInsertSort { public static void binaryInsertSort(DataWrap [] data) { System.out.println("开始排序:"); int length = data.length; for(int i = 1;i < length;i++) { //当整体后移时,保证data[i]的值不会丢失 DataWrap tmp = data[i]; int low = 0; int high = i-1; while(low <= high) { //找出low,high中间的索引 int mid = (low+high)/2; //如果tmp值大于low、high中间元素的值 if(tmp.compareTo(data[mid]) >0) { //限制在索引大于mid的那一半中搜索 low = mid +1; } else { //限制在索引小于mid的那一半中搜索 high = mid -1; } } //将low到i处的所有元素向后整体移一步 for(int j = i; j > low ;j-- ) { data[j] =data[j-1]; } //最后将tmp的值插入合适位置 data[low] = tmp; System.out.println(java.util.Arrays.toString(data)); } } public static void main(String[] args) { DataWrap[] data = { new DataWrap(21, ""), new DataWrap(30, ""), new DataWrap(49, ""), new DataWrap(30, ""), new DataWrap(16, ""), new DataWrap(9, ""), new DataWrap(-16, "") }; System.out.println("排序之前:\n" + java.util.Arrays.toString(data)); binaryInsertSort(data); System.out.println("排序之后:\n" + java.util.Arrays.toString(data)); } }
