递归、StringBuilder中reverse（）对数据进行反转，

package com.lx;

public class TEST {
  //递归
    public static String reverse(String originStr) {
        if(originStr == null || originStr.length() <= 1) {
            return originStr;
        }else{
         return reverse(originStr.substring(1)) + originStr.charAt(0);
        }
    }



    public static void main(String[] args) {
        String  s="sfghj";
        System.out.println(reverse(s));
        StringBuilder b = new StringBuilder(s);
       System.out.print(b.reverse().toString());
    }
