步骤 代码实现 importjava.util.Arrays;importjava.util.Comparator;publicclassArraySortReverse{publicstaticvoidmain(String[]args){// Step 1: Declare an integer arrayInteger[]arr={5,2,8,1,3};// Step 2: Use Arrays.sort
1.Array.sort(数组,起始位置,结束位置)。这个是升序排序。 2.关于数组的降序实现如下: 利用Collections.reverseOrder()方法: importjava.util.Arrays;importjava.util.Collections;publicclassMain {publicstaticvoidmain(String[] args) {int[] a = {9, 8, 7, 2, 3, 4, 1, 0, 6, 5}; Arrays.sort(a...
②使用Arrays.sort(数组名)语法对数组进行排序,排序规则是从小到大,即升序。 降序主要是利用Collections.reverseOrder()方法。具体我们看代码吧~ 四、实战 1、 2、 3、 4、 源码 1、 代码语言:javascript 代码运行次数:0 运行 AI代码解释 package array; public class yiwei { public static void main(Stri...
// Unsorted string array String[] strArray = {"Alex","Charles","Dean","Amanda","Brian"}; // Sorting the strings Arrays.sort(strArray); // Sorted array System.out.println("Sorted : "+ Arrays.toString(strArray)); Arrays.sort(strArray, Comparator.reverseOrder()); // Reverse Sorted ar...
String s[] = in.readLine().split(" ");// 读入数据Arrays.sort(s,newComparator<String>() {// 排序publicintcompare(String a, String b){if(a.length() == b.length()){// 如果长度相等则直接比较字典序returna.compareTo(b); }else{// 长度长的一定大returna.length() - b.length(); ...
Java语言提供给我们Array.sort(int [] arr)对数组进行升序排列,代码如下: package song; import java.util.Arrays; public class Testexample { public static void main(String[] args) { int[] a = {9, 8, 7, 2, 3, 4, 1, 0, 6, 5}; ...
