I need to know that how to set input data to object to get the output in class below.

Question

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 customers data to object here
customer.firstName = read.nextLine();
customer.secondName = read.nextLine();
customer.age = read.nextInt();
customer.roomNumber = read.nextInt();

customer.saveCustomerInfo();
}
}

class Customer {
String firstName;
String secondName;
int age;
int roomNumber;

//add all necessary attributes here

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);
}
}
My attempt is as above. I'm unable.

Answer 1

you are scanning everything two times one via main variables and the other through your class variables which is wrong as u must have entered only once in your input stream
The below code is correct
public static void main(String[] args) {
Scanner read = new Scanner(System.in);
Customer customer = new Customer();
//set customers data to object here
customer.firstName = read.nextLine();
customer.secondName = read.nextLine();
customer.age = read.nextInt();
customer.roomNumber = read.nextInt();

customer.saveCustomerInfo();
}
}

class Customer {
String firstName;
String secondName;
int age;
int roomNumber;

//add all necessary attributes here

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);
}
}
