我收到错误消息“找不到符号类键盘阅读器”。我究竟做错了什么？

import java.util.Scanner;
public class Looping
{
public static void main(String[] args)
{
KeyboardReader reader = new KeyboardReader();
 int choice = 0;

//Menu with options
do {
System.out.println("Looping Menu");
System.out.println("1. For Loop");
(And so on, with a menu and options that work fine)
}
}

最佳答案
