Why it's not running

Question

/*You are the administrator of a hotel and must create customer information cards for your new customers. On the card, you must note the customer’s first and last name, age, and room number.
The program you are given takes a guest's data (first name, last name, age, and room number) as input.
Complete the class by adding corresponding attributes so that the saveCustomerInfo() method works correctly. Also assign taken data values to attributes of created object.

Sample Input
John
Smith
35
204

Sample Output
First name: John
Second name: Smith
Age: 35
Room number: 204*/

Answer 1

You have 2 task here to complete it.
1) set customer's data to object there..
** assign input values to object properties...

2) add all necessary attributes..
** declare attributes before which you using the method for display information..

What code you added to this incomplete code actually?
Nothing I think, before attempting.. Revise the lessons of class and object, it's properties, one more time...
Hope it helps...

Answer 3

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner read = new Scanner(System.in);
String firstName = read.nextLine();
String secondName = read.nextLine();
int age = read.nextInt();
int roomNumber = read.nextInt();
Customer customer = new Customer();
//set customer's data to object here

customer.saveCustomerInfo();
}
}

public class Customer {
//add all necessary attributes here

public static void saveCustomerInfo() {
System.out.println("First name: "+firstName);
System.out.println("Second name: "+secondName);
System.out.println("Age: "+age);
System.out.println("Room number: "+roomNumber);
}
}

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner read = new Scanner(System.in);
String firstName = read.nextLine();
String secondName = read.nextLine();
int age = read.nextInt();
int roomNumber = read.nextInt();
Customer customer = new Customer();
//set customer's data to object here
customer.firstName="John";
customer.secondName="Smith";
customer.age=35;
customer.roomNumber=204;

customer.saveCustomerInfo(firstName ,secondName ,age ,roomNumber);

}
}

class Customer {
//add all necessary attributes here
String firstName;
String secondName;
int age;
int roomNumber;

public void saveCustomerInfo(String firstName,String secondName,int age,int roomNumber) {
System.out.println("First name: " + firstName);
System.out.println("Second name: " + secondName);
System.out.println("Age: " + age);
System.out.println("Room number: " + roomNumber);
}
}
