我试着用两个班成员班和网站班互相交谈。我想使用member类的setloggedinstatus（）方法中的代码，并且能够在website类的memberlogin（）方法中使用它。我用了 Member memberObject = new setloggedInStatus(); 但它给了我一个错误。
如果有任何帮助，我将不胜感激。提前谢谢
网站类

public class Website
{
    // declaration of vars 
    private String websiteName;
    private int hits; 
    private double salesTotal; 

    /**
     * Constructor for objects of class Website
     */
    public Website(String websiteName)
    {
        // initialise instance variables
         this.websiteName = websiteName;  
    }

    Member memberObject = new setloggedInStatus(); 

   public void memberLogin() {

    }
}

成员类

public class Member
{
    // varibales declaration 
    private String email;  
    private int membershipNumber; 
    private boolean loggedInStatus; 

    /**
     * Constructor for objects of class Member
     */
    public Member(String memberEmail, int newMembershipNumber )
    {
        // initialise instance variables
        email = memberEmail;
        membershipNumber = newMembershipNumber;
    }

    //loggedInStatus method
    public void setloggedInStatus() {
    if (email != null && membershipNumber != 0) {
        loggedInStatus = true;
        System.out.println("you are logged in ");

    } 

    else {
        loggedInStatus = false;
        System.out.println("you are not logged in");
    }
}

    }
