(字符串转数组，数组转字符串)

import java.util.Scanner;//对字符串排序 import java.util.Arrays; public class text20{ public static void main(String[] args){ Scanner in=new Scanner(System.in); System.out.print(“Enter a String:”); String strs=in.nextLine(); System.out.println(“After sort:”+sort(strs)); } public static String sort(String strs){ char[] list=new char[strs.length()]; list=strs.toCharArray();//**字符串->字符数组 for(int i=0;i<strs.length();i++){ for(int j=i+1;j<strs.length();j++){ if(list[i]>list[j]){ char temp=list[i]; list[i]=list[j]; list[j]=temp; } } } return new String(list);//**字符数组->字符串 } }
