【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("
- -------------- --- -
");
        
        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……
