java实现字符按照ASCII排序_java ascii排序

给定一个字符串，将里面的字符按照ASCII码进行排序

方法一：直接使用Arrays里的sort方法

import java.util.*;
 
public class App {
 
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String str = sc.nextLine();
        char[]chars = str.toCharArray();
        Arrays.sort(chars);
        System.out.println(new String(chars));
    }
}

方法二：使用双重循环

import java.util.*;
 
public class App {
 
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String str = sc.nextLine();
        char[]chars = str.toCharArray();
        char temp;
        for (int i=0;i<chars.length;i++){
            for (int j=0;j<chars.length-1;j++){
                if(chars[j]>chars[j+1]){
                    temp = chars[j];
                    chars[j] = chars[j+1];
                    chars[j+1] = temp;
                }
            }
        }
        String printStr = "";
        for (int k=0;k<chars.length;k++){
            printStr = printStr + chars[k];
        }
        System.out.println(printStr);
    }
}
