Following is the answer:

import java.text.SimpleDateFormat; public class BloodDonor { //variables long idNumber, cardNumber; String name, bloodGroup, homePhone, mobilePhone, address, lastDateOfDonation; //SimpleDateFormat class is used to parse and format dates in a given format SimpleDateFormat myFormat = new SimpleDateFormat("dd MM yyyy"); //Default constructor that set the default value to all variables public BloodDonor() { this.idNumber = 0; this.cardNumber = 0; this.name = ""; this.bloodGroup = ""; this.homePhone = ""; this.mobilePhone = ""; this.address = ""; this.lastDateOfDonation = ""; } //Constructor with parameter that pass parameters to set the values public BloodDonor(long idNumber, long cardNumber, String name, String bloodGroup, String homePhone, String mobilePhone, String address, String lastDateOfDonation) { this.idNumber = idNumber; this.cardNumber = cardNumber; this.name = name; this.bloodGroup = bloodGroup; this.homePhone = homePhone; this.mobilePhone = mobilePhone; this.address = address; this.lastDateOfDonation = lastDateOfDonation; } //Setter method setName to set the name public void setName(String name) { this.name = name; } //Setter method setAddress to set the address public void setAddress(String address) { this.address = address; } //Setter method setBloodGroup to set the bloodgroup public void setBloodGroup(String bloodGroup) { this.bloodGroup = bloodGroup; } //Setter method setCardNumber to set the cardNumber public void setCardNumber(long cardNumber) { this.cardNumber = cardNumber; } //Setter method setHomePhone to set the homePhone public void setHomePhone(String homePhone) { this.homePhone = homePhone; } //Setter method setIdNumber to set the Id public void setIdNumber(long idNumber) { this.idNumber = idNumber; } //Setter method setMobilePhone to set the MobilePhone public void setMobilePhone(String mobilePhone) { this.mobilePhone = mobilePhone; } //Setter method setLastDateOfDonation to set the lastDonationdate public void setLastDateOfDonation(String lastDateOfDonation) { this.lastDateOfDonation = lastDateOfDonation; } //Getter method to get name public String getName() { return name; } //Getter method to get address public String getAddress() { return address; } //Getter method to get card number public long getCardNumber() { return cardNumber; } //Getter method to get Id public long getIdNumber() { return idNumber; } }
