Calling reverse() on the array reverses the order to 5, 4, 3, 2, 1. The sort() method puts the items in ascending order. The sort() method calls the String() casting function on every item and then compares the strings to determine the correct order. This occurs even if all items ...
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[] nums =newint[]{...
Array.Reverse是反向输出数组; Array.Sort是对数组进行排序; 小例子: classProgram {staticvoidMain(string[] args) {int[] arr1 =newint[] {1,3,8,5,39,2,4,6,7};//输出一个数组foreach(intninarr1) Console.Write(n+""); Console.WriteLine(); ...
一、常用的数组操作 1.数据添加push() 2.数组移除最后一个数据项pop() 3.数组顺序倒置,颠倒reverse() 4.数组排序sort(),数字排在字线前 5.数组截取splice(数组开始位置,截取数据项个数),原数组则去掉截取的这部分数组 <!DOCTYPE html> ...
方法一:使用Array.Reverse()方法 首先,使用Array.Sort()方法对数组进行排序。 然后,使用Array.Reverse()方法将排序后的数组进行反转,以得到按降序排序的结果。 下面是示例代码: 代码语言:txt 复制 int[] array = { 5, 2, 8, 1, 9 }; // 使用Array.Sort()方法对数组进行排序 Array.Sort(array); // ...

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:
