Data sorting in string

demand ： There's a string ：“91 27 46 38 50”, Please write a program to achieve the final output ：“27 38 46 50 91”

analysis ：
The first step is to separate the numbers in the string （ According to the space ） Put it in an array ;
Step 2 sort the array ;
The third step is to sort and convert it into string splicing again ;

Split the string according to the space ：https://blog.csdn.net/yezonghui/article/details/106455940

Concrete realization ：

1. Define a string
2. Store the numeric data in the string into a int In an array of types ;
   public String[] split(String regex) : Get every digital data
   public static int parseInt(String) : Store every data in int Array
3. Yes int Array to sort ;
4. The sorted array elements are spliced to get a string
   use StringBuilder To realize ;
5. Output results ;

package Integerr;

import java.util.Arrays;

public class StringSort {
    
    public static void main(String[] args) {
    
        
        String s = "91 27 46 38 50";    // 1
        String[] strArray = s.split(" "); // 2
        int[] intArr = new int[strArray.length];

        for (int i = 0; i < intArr.length; i++) {
    
            intArr[i] = Integer.parseInt(strArray[i]);
        }
        Arrays.sort(intArr); //3

        StringBuilder sb = new StringBuilder();   //4
        for (int i = 0; i < intArr.length; i++) {
    
            if (i == intArr.length - 1) {
    
                sb.append(intArr[i]);
            } else {
    
                sb.append(intArr[i] + " ");
            }
        }

        String s2 = new String(sb);   //5
        System.out.println(s2);
    }
