Hello😊 I do not know exactly what is meant by „set customer's data to object here" . Can someone help me there? Thank you

You can set customer data like this

customer.firstName = firstName;

here you are setting data in class attribute using object. Why object because you must tell that attribute belongs to the specific class. Because there maybe many classes with same attributes.

This one is working.)

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();
//присвойте данные клиента атрибутам объекта

Customer.firstName = firstName;
Customer.secondName = secondName;
Customer.age = age;
Customer.roomNumber = roomNumber;

customer.saveCustomerInfo();
}
}

class Customer {
//добавьте все необходимые атрибуты здесь
static String firstName, secondName;
static int age, 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);
}
}

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();

Customer.firstName = firstName;
Customer.secondName = secondName;
Customer.age = age;
Customer.roomNumber = roomNumber;

customer.saveCustomerInfo();
}
}

class Customer {

static String firstName, secondName;
static int age, 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);
}
}
