java(字符串的反转)

需求:键盘录入一个字符串，利用代码将字符串反转。

import java.util.Scanner;
public class Boke {
    public static void main(String[] args){
        Scanner Sc = new Scanner(System.in);
        System.out.print("请输入一个字符串:");
        String x =Sc.next();
        String cout = "";
        for (int i = x.length()-1; i >=0 ; i--) {
            char c =x.charAt(i);
            cout+=c;
        }
        System.out.print(cout);
    }
}
