I have created a constructor that has many parameters. I want it to take inputs through user. However, when I run the program it does not take all inputs and jumps the last STRING input. How to Solve this issue?
The practice problem that I am solving is: For each attributes described below, choose appropriate data type. All the attributes of each class should be private and exposed via get/set methods. Also define at least one constructor that allows to initialize 2-3 attributes of object. Define a class Course with courseCode and courseTitle instance variable. Define PhoneNumber class with countryCode, cityCode and lineNumber attributes. Define a class Address with streetAddress, town, city, country and phoneNumber attributes. The phoneNumber shall be of type PhoneNumber. Define a class Student with name, email, CNIC, course1, course2 and address attributes. Where course1 and course2 should be of type Course and address shall be of type Address. Define a constructor in Student class that shall take CNIC, name and address only. Create a StudentTest class. In its main method, create a Student object named student1. Fully initialize its all attributes. CNIC, name and address shall be initialized using constructor. Other attributes shall be initialized using setter methods. All attributes' values shall be given by user. After the object is fully initialized, print all attribute values using get methods. Make another object student2, assume the user also live at same address as student1. Reuse the address object of student1 to initialze student2 address. You don't need to take attributes from user input for student2 object. Print the values of all instance variables.
MY CODE:
StudentTest Class
import java.util.Scanner;
public class StudentTest {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter Country Code, City Code and Line Number (SEPARATELY): ");
PhoneNumber phoneNumber = new PhoneNumber(sc.nextInt(), sc.nextInt(), sc.nextInt());
System.out.println("Enter Street Address, Town, City and Country (SEPARATELY): ");
Address address = new Address(sc.nextLine(), sc.nextLine(), sc.nextLine(), sc.nextLine(), phoneNumber);
System.out.println("Enter Name and CNIC Number of Student 1 (SEPARATELY): ");
Student student1 = new Student(sc.nextLine(), sc.nextLine(), address);
System.out.println("Enter Email Address for Student 1: ");
student1.setEmail(sc.nextLine());
System.out.println("Course 1: Enter Course Title: ");
student1.getCourse1().setCourseTitle(sc.nextLine());
System.out.println("Course 1: Enter Course Code: ");
student1.getCourse1().setCourseCode(sc.nextInt());
System.out.println("Course 2: Enter Course Title: ");
sc.nextLine(); //Dummy Input for String
student1.getCourse2().setCourseTitle(sc.nextLine());
System.out.println("Course 2: Enter Course Code: ");
student1.getCourse2().setCourseCode(sc.nextInt());
System.out.println("--------------------------------------------------------------------------------");
System.out.println("Student 1 Details:");
System.out.println("Name: "+student1.getName());
System.out.println("CNIC: "+student1.getCnic());
System.out.println("Address: " + student1.getAddress().getStreetAddress() + " , " + student1.getAddress().getTown()
+ " , " + student1.getAddress().getCity() + " , " + student1.getAddress().getCountry()
+ " , " + student1.getAddress().getPhoneNumber().getCountryCode()
+ student1.getAddress().getPhoneNumber().getCityCode() + student1.getAddress().getPhoneNumber().getLineNumber());
System.out.println("Email: "+student1.getEmail());
System.out.println("Course 1: Course Title: "+student1.getCourse1().getCourseTitle() + " | "
+ "Course Code: " + student1.getCourse1().getCourseCode());
System.out.println("Course 2: Course Title: "+student1.getCourse2().getCourseTitle() + " | "
+ "Course Code: " + student1.getCourse2().getCourseCode());
System.out.println("--------------------------------------------------------------------------------");
Student student2 = new Student("John", "35202", address);
student2.setEmail("Student_02_Email@java.com");
student2.getCourse1().setCourseTitle("EMO");
student2.getCourse1().setCourseCode(105);
student2.getCourse2().setCourseTitle("LA");
student2.getCourse2().setCourseCode(102);
System.out.println("--------------------------------------------------------------------------------");
System.out.println("Student 2 Details:");
System.out.println("Name: "+student2.getName());
System.out.println("CNIC: "+student2.getCnic());
System.out.println("Address: "+student2.getAddress().getStreetAddress() + " , " + student2.getAddress().getTown()
+ " , " + student2.getAddress().getCity() + " , " + student2.getAddress().getCountry()
+ " , " + student2.getAddress().getPhoneNumber().getCountryCode()
+ student2.getAddress().getPhoneNumber().getCityCode() + student2.getAddress().getPhoneNumber().getLineNumber());
System.out.println("Email: "+student2.getEmail());
System.out.println("Course 1: Course Title: "+student2.getCourse1().getCourseTitle() + " | "
+ "Course Code: " + student2.getCourse1().getCourseCode());
System.out.println("Course 2: Course Title: "+student2.getCourse2().getCourseTitle() + " | "
+ "Course Code: " + student2.getCourse2().getCourseCode());
