将字符串转换为char并按降序排序（ascii）

本文介绍了将字符串转换为char并按降序排序（ascii）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我创建了一个程序，它将使用户输入整数（一个接一个），存储在数组中，并按降序显示整数。程序还要求用户输入一个字符串将其转换为char使用 string.toCharArray（）。我已经正确完成显示整数的降序。 这是整数的代码： for（i = 0; i System.out.print（为索引[+ i + - >）; nums [i] = Integer.parseInt（br.readLine（））;} while（pass for（i = 0; i if（nums [i] temp = nums [i] nums [i] = nums [i + 1]; nums [i + 1] = temp; } } pass ++; } System.out.println（\\\\\\按降序排序的数字为：\\\）; for（i = 0; i System.out.println（nums [i]）; 这是字符串到数组的代码。这是我有问题的地方。我没有运行程序的错误只是我不知道如何正确地做。 System.out .print（Input a string）; String strValue = br.readLine（）; char [] chrValues; chrValues = strValue.toCharArray（）; while（flag< chrValues.length）{ for（c = 0; c if（chrValues [c] < chrValues [i + 1]）{ tempo = chrValues [c]; chrValues [c] = chrValues [c + 1]; chrValues [c + 1] = tempo;} } } 标志++; System.out.println（\\\\\\以字符转换并按降序排序的字符串为：\\\）; for（c = 0; i System.out.println（chrValues [c]）;} 解决方案 p $ p> 您可以尝试 String str =AbCdEf; char [] arr = str.toCharArray（）; for（int i = 0; i System.out.println（）; Arrays.sort（arr）; //按升序排序 //向后打印，即按降序排列。 for（int i = arr.length-1; i> = 0; i--）System.out.print（arr [i]）; System.out.println（）; print AbCdEf fdbECA I am creating a program which will make the user input integer (one after another), stored in array and display the integers in descending order. The program also ask to the user to input a string convert it to char using string.toCharArray(). I've correctly done displaying the integer into descending order. The problem is I don't know how to display the char descendingly.This is the code for the integer:for(i=0;i<nums.length;i++){ System.out.print("Enter value for index["+i+"] here --> "); nums[i]=Integer.parseInt(br.readLine());}while(pass<nums.length){ for(i=0;i<(nums.length-pass);i++){ if(nums[i]<nums[i+1]){ temp=nums[i]; nums[i]=nums[i+1]; nums[i+1]=temp; } } pass++;}System.out.println("\n\nThe numbers when sorted descendingly are :\n"); for(i=0;i<nums.length;i++){ System.out.println(nums[i]);This is the code for the string to array. This is where i'm having problems. I don't have errors in running the program just it's just I don't how to do it correctly.System.out.print("Input a string"); String strValue= br.readLine(); char[] chrValues; chrValues=strValue.toCharArray( );while(flag<chrValues.length){ for (c=0; c< (chrValues.length- flag); c++){ if(chrValues[c]<chrValues[i+1]){ tempo=chrValues[c]; chrValues[c]=chrValues[c+1]; chrValues[c+1]= tempo;} }} flag++; System.out.println("\n\nThe String when converted in character and sorted descendingly are :\n"); for(c=0;i<chrValues.length;c++){ System.out.println(chrValues[c]);}By the way, I used flag as a temporary array storage. 解决方案 You can tryString str = "AbCdEf";char[] arr = str.toCharArray();for(int i = 0; i < arr.length; i++) System.out.print(arr[i]);System.out.println();Arrays.sort(arr); // sorted in ascending order// print them backwards i.e. descending order.for(int i = arr.length - 1; i >= 0; i--) System.out.print(arr[i]);System.out.println();printsAbCdEffdbECA 这篇关于将字符串转换为char并按降序排序（ascii）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
