这个简单的登录检测问题到底出在哪？不管怎么输入都提示密码错误。

import java.util.Scanner;
public class E4{
    public static void main(String[] args){
        Scanner sc= new Scanner(System.in);
        int password=666;
        String name = "Dingzhen";
        for(int i = 1; i<=3;i++){
            System.out.println("请输入您的用户名：");
            String sname = sc.next();
            System.out.println("请输入您的密码：");
            int spassword = sc.nextInt();
            if(sname==name && spassword == password){
                System.out.println("登录成功");
                break;
            }else{
                System.out.println("密码或用户名错误，剩余机会："+(3-i));
            }
        }
    }
}
