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
String firstName;
String secondName;
int age;
int roomNumber;

public 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);
}
}

Answer 1

You are not set or assigned any values in customer class but printing.so thats why all default values you get..
define Customer constructor to set data fields.. and
Send or Set input values through constuctor of customer. Print next...
