Using multiple Classes.

Question

How Would I use the guestName, guestAddress, and others in the other public class Main()? When I use name = input.nextLine();, it states that it "cannot resolve symbol "name"". I want to use the private variables from the Identification class and implement them in the Main class.

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);
    Identification guest = new Identification();

    guest.Identification();
    System.out.println("Welcome to the Motel");
    System.out.println("Please answer the following Questions to Check In: ");
    System.out.println("Enter your Full Name: ");
        name = input.nextLine();
    System.out.println("Enter your Address: ");
        address = input.nextLine();
    System.out.println("Date of Birth: ");
        dateOfBirth = input.nextInt();
    System.out.println("Enter your Identification Card Number or SSC number: ");
        iD = input.nextInt();

}

}

public class Identification {

    private String guestName;
    private String guestAddress;
    private String guestSignature;
    private int guestDateOfBirth;
    private int guestIdentificationNumber;

    public Identification(String guestName, String guestAddress, String guestSignature, int guestDateOfBirth, int guestIdentificationNumber) {
        this.guestName = guestName;
        this.guestAddress = guestAddress;
        this.guestSignature = guestSignature;
        this.guestDateOfBirth = guestDateOfBirth;
        this.guestIdentificationNumber = guestIdentificationNumber;
    }

public String getGuestName () {
    return guestName;
}
public void setGuestName (String name){
    guestName = name;
}

public String getGuestAddress () {
    return guestAddress;
}
public void setGuestAddress (String address){
    guestAddress = address;
}

public String getGuestSignature () {
    return guestSignature;
}
public void setGuestSignature (String signature){
    guestSignature = signature;
}

public int getGuestDateOfBirth () {
    return guestDateOfBirth;
}
public void setGuestDateOfBirth ( int dateOfBirth){
    guestDateOfBirth = dateOfBirth;
}

public int getGuestIdentificationNumber () {
    return guestIdentificationNumber;
}
public void setGuestIdentificationNumber ( int iD){
    guestIdentificationNumber = iD;
}

}

The variable name hasn't been declared yet. Try adding String in front of it, to declare the variable instead of just referencing it:

String name = input.nextLine();

You can set the property on your guest instance with the setter method:

guest.setGuestName(name);

The name property of Identification is private, but you can set it with the public method setGuestName.
