【API】反转输入字符（Java）

请求输入字符，

输出反转。

 import java.util.Scanner;

 public class T01 {

     public static void main(String[] args) {
         /**
          * get str from kbd
          * out a new str that sakasamad
          */
         System.out.print("in put a str :  | ");
         String str = new Scanner(System.in).nextLine();
         str = new StringBuilder(str).reverse().toString();
         System.out.print("FanZhuan :      | "+str);

         System.out.println("\n- -------------- --- -\n");

         System.out.print("in put a str :  | ");
         System.out.print("FanZhuan :      | "+new StringBuilder(new Scanner(System.in).nextLine()).reverse().toString());

         //well... i don't know how to use close() now...
     }
 }

试了试行数更少的写法，还真也行，输出效果没有坏掉。

话说玩API比搞项目舒服多了……
