Scanner录入出现错误，在线等，很着急！！！帮帮我

Question

信息类：

 import java.util.Scanner;

public class UserInf {
    final private String userName = new String("JiHe");
    final private String passWord = new String("JiHe123");

    public UserInf() {
        super();
        // TODO Auto-generated constructor stub
        check();
    }

    public void check() {
        System.out.println("Please input userName:");
        Scanner sc = new Scanner(System.in);
        if (this.userName.equals(sc.nextLine())) {
            if (this.passWord.equals(sc.nextLine())) {
                System.out.println("Please input passWord:");
                System.out.println("Check Pass !");
            }
        }
    }
}

测试类：

 public class TestUser {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        UserInf user = new UserInf();
    }

}

问题：console只输出一句，无法输出第二句：

 Please input userName:
JiHe

恳请有爱心的你不吝惜赐教！

Answer 1

if (this.passWord.equals(sc.nextLine())) {

你输入完名字紧接着输入密码，但是你现在没有输入密码啊
哈哈
少了一个输入密码的提示
System.out.println("Please input passWord:");
if (this.passWord.equals(sc.nextLine())) {
