public static void sort(int[] a) { DualPivotQuicksort.sort(a, 0, a.length - 1, null, 0, 0); } 1. 2. 3. 继续查看DualPivotQuicksort,茫茫多的代码,根据给出的输入条件可以找到 if (right - left < QUICKSORT_THRESHOLD) { sort(a, left,
由于在JDK6之前,对象数组的默认排序方式是直接采取legacyMergeSort算法 = 插入排序+分治思想+归并的思路对数组内元素进行排序的,当元素没有具体值时,则会根据数组中的假定的比较器Comparable.compareTo进行元素的比较排序。 legacyMergeSort算法 内部采取的是mergeSort并归思路,当数组元素小于7时,会采取插入排序的方式将...
2、Arrays.sort(int[] a, int fromIndex, int toIndex) 这种形式是对数组部分排序,也就是对数组a的下标从fromIndex到toIndex-1的元素排序,注意:下标为toIndex的元素不参与排序哦! 举例如下(点“+”可查看代码): importjava.util.Arrays; publicclassMain {4publicstaticvoid main(String[] args) {int[] a ...
