您好，提问者：
    没有导入包造成的，修改如下：

import java.io.Console;//加上这句
public class Student{
    /xxx

Console好像不能在IDE里面使用.
建议使用BufferedReader:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String s = br.readLine();

Console.ReadLine
R大写，还有你导包正确了没？
