冒泡算法对String字符串的数据进行排序

public class test {
    public static void main(String[] args) {
        String s = "58627";
        //split转换s为arr数组
        String[] arr =  s.split("");
        //冒泡对arr数组进行排序
        for(int i=0;i<arr.length-1;i++){
            for (int j=0;j<arr.length-1-i;j++) {
                if(Integer.parseInt(arr[j])>Integer.parseInt(arr[j+1])){
                    String temp = arr[j+1];
                    arr[j + 1] = arr[j];
                    arr[j] = temp;
                }
            }
        }
        //数组arr转换成字符串finalString
        StringBuilder sb = new StringBuilder();
        for (String s1 : arr) {
            sb.append(s1);
        }
        String finalString = sb.toString();
        System.out.println(finalString);
    }
