在Eclipse中获取错误"无法实例化类型扫描程序"

Question

我正在尝试学习java但是在处理Scanner类型时我遇到了错误,"无法实例化类型扫描程序".这是我的代码

import com.sun.java_cup.internal.runtime.Scanner;

public class Main {
    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);
        int a = 2;

        for (int i = 1; i != 10; i++) {
            System.out.println(a + " X " + i + " = " + a * 1);
        }
        int i = 1;
        while (i != 10) {
            System.out.printf("%d X %d = %d\n", a + 10, i, (a + 10) * i);
            i++;
        }
    }
}

你是Scanner从错误的包导入.将导入更改为:

import java.util.Scanner;
