仔细分析java的Arrays.sort(version 1.71, 04/21/06)后发现,java对primitive(int,float等原型数据)数组采用快速排序,对Object对象数组采用归并排序。 对这一区别,sun在<<The Java Tutorial>>中做出的解释是: The sort operation uses a slightly optimized merge sort algorithm that is fast and stable: * Fast:...
1.一维数组排序 int[] intArray =newint[]{1,34,5,-9}; Arrays.sort(intArray); System.out.println(Arrays.toString(intArray)); 2.一维数组逆序 Java的Arrays.sort()仅支持对引用数据类型进行自定义排序,如果是基本数据类型(如int类型),将无法使用Comparator进行自定义排序。 可以先正序再reverse int[] n...

Sorting an Array Thesort()method sorts an array alphabetically: Example constfruits = ["Banana","Orange","Apple","Mango"]; fruits.sort(); Try it Yourself » Reversing an Array Thereverse()method reverses the elements in an array:
The next optimization is to write the quad swap analyzer in such a way that we can perform a simple check to see if the entire array was in reverse order, if so, the sort is finished. At the end of the loop the array has been turned into a series of ordered blocks of 8 elements...
