我正在努力学习java，我的代码有一些问题。我试图使用if语句来检查是否有任何输入到构造函数中。如果输入了电子邮件字符串和成员编号，check logged in status方法应返回用户已登录。另一方面，它应该返回他们没有登录。

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 == email && membershipNumber == membershipNumber ) {

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