Further Programming in Java

SOE1 - Code

20% of final grade 

Register

This code will also form the base for SOE2 so it is essential you complete this assessment.

The program is a simple registration system stored using a HashMap. The key in the HashMap is the students last name, the data is an instance of the Student class.

Instructions

Student Class

Complete the Student class. Define Setters and Getters for all of the fields.

Add a toString method to the class that returns the following String as a CSV

0001,SMITH,Jane,10/02/2000,BN2 7BB

The items in the String above in order are:

the registration number padded left to a size of 4

· lastName

· firstName

· dateOfBirth

· postCode

import java.io.Serializable;
public class Student implements Person, Serializable {
    private int registrationNumber;
    private String lastName;
    private String firstName;
    private String dateOfBirth;
    private String postCode;
}

StudentRegister Class

Complete the following methods in the Register class

public class StudentRegister implements Register, Serializable {
    private HashMap<String, Student> studentRegister;
    private final String DATA_FILE = "resources/register.ser";
    public StudentRegister() {
        studentRegister = new HashMap<>();
    }

         public boolean isValidName(String name)

Complete the method to check if name is valid - only alphabetic chars are allowed.

Print out a detailed error message if the method finds any problems in the String.

Return true if the String is OK, false if not OK.

    public boolean isValidDate(String dateStr)

Complete the method to check dateStr represents the standard UK date format dd/mm/yyyy

Print out a detailed error message if the method finds any problems in the String.

Return true if the String is OK, false if not OK.

    public boolean isValidPostCode(String postCode)

Complete the method to check if postCode represents a valid UK postcode. Format rules are:

· Starts with 1 or 2 characters A to Z

· Followed by a single digit

· Followed by an optional Single digit

· Followed by 1 character A to Z

· Followed by a space

· Followed by a single digit

· Followed by 2 characters A to Z

Print out a detailed error message if the method finds any problems in the String.

Return true if the String is OK, false if not OK.

    public Integer addStudent(String studentStr)

Complete the method to add a student to the register using a single formatted CSV String studentStr to add the student. 

You need to use the methods above to check if each part of the String is valid. 

As this represents a new Student being added to the system calculate the registrationNumber using the number of items in the list once the Student has been added. 

Check is the key (lastName) is already in the studentRegister. If it is give a warning message and do not add it. 

Method returns the registrationNumber or null if the student was not added to the register.

    public void printRegister()

Complete the method to print the contents of the studentRegister. Only print the values in the HashMap

These latter two methods are complete and do not need to be changed

    public void readRegisterFile() {
        studentRegister = FileIO.readSerialDataFromFile(DATA_FILE);
    }
    public void writeRegisterFile() {
        FileIO.writeSerialDataToFile(DATA_FILE, studentRegister);
    }
}

Main Code

public class Main {
    public static void main(String[] args) {
        StudentRegister studentRegister = new StudentRegister();
        studentRegister.readRegisterFile();
        studentRegister.addStudent("DOE,John,10/02/2001,BN1 7AT");
        studentRegister.addStudent("SMITH,Sarah,6/7/2002,BN2 6WV");
        studentRegister.addStudent("BROWN,Alice,12/12/1999,BN3 9TT");
        studentRegister.addStudent("BROWN,Simon,16/3/1998,BN41 8TZZ");
        studentRegister.addStudent("ARCHER,Simon,40/13/200,BN41 8TZZ");
        studentRegister.addStudent("WALKER,George,10/4/1999,A1 8T");
        studentRegister.printRegister();
        studentRegister.writeRegisterFile();
    }
}

Code is complete and has test data
