Error in java Exception in thread "main"

The error it presents is:

  

Exception in thread "main" java.util.NoSuchElementException: No line   found at java.util.Scanner.nextLine (Unknown Source).

I have a readAddress method that gets the values of the class. This method is called from another class Employee to read Address of Employee among other attributes. I attach the two methods. When I test the methods separately it works well.

public void readAddress() {

    Scanner read = new Scanner(System.in);
    String string;

    System.out.println("Address(Separate each data with '/'): ");
    string = read.nextLine();

    String[] substring = string.split("/");

    this.building = substring[0];
    this.apartment = substring[1];
    this.street = substring[2];
    this.city = substring[3];
    this.province = substring[4];
    this.code = substring[5];
    read.close();
}

public void readEmployee() {

    Scanner read = new Scanner(System.in);


    System.out.println("Last name: ");
    this.lastname = read.nextLine();
    System.out.println("First name: ");
    this.firstname = read.nextLine();
    this.email.readEmail();
    this.address.readAddress();
    this.telephone.readTelephone();
    System.out.println("Social security number: ");
    this.ssn = read.nextLine();
    read.close();
}

The error is on the line:

string = read.nextLine();
