这段代码为什么会报错，谁帮我看一下

Question

```java


import java.util.Scanner;// 导包
public class Login{ //用户登录
    public static void main(String[]args){
    Scanner input = new Scanner(System.in);//创建Scanner对象
    System.out.print("please input users name："); //屏幕显示
    String useName=input.next();//输入用户名
    System.out.print("please enter the password：");//输入密码
    int pwd=input.nextInt();//输入密码
    //双分支结构 if-else
    if("wangwu".equals(userName)&&pwd==123456)
    {//判断用户名和密码
        System.out.println("successful");


    }else{
        System.out.println("I am sorry, you could not get in");
        }
    }
}

```java
Login.java:10: error: cannot find symbol
        if("wangwu".equals(userName)&&pwd==123456)
                           ^
