编辑：你们可以教我如何在程序包中添加用户类吗？我不知道
您好，我是一个初学者，但是我可以问为什么writenewuser用户user =新用户说无法解析符号用户吗？我计划喜欢在数据库上添加登录详细信息，然后在其上设置1或2的值，以便我可以选择注册用户要使用的仪表板。但是，自从每次我与公共无效的writenewuser一起搜索指南或样本时，我就感到困惑。 “用户用户=新用户”代码将始终是错误消息，提示“无法解析符号用户”

最佳答案
您需要像以下示例一样创建类User：
public class User{
private String name,email;
public User(){
}
public User(String name, String email){
this.name=name;
this.email=email;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email=email;
}
}
