Question

Create a class named BloodData that includes fields that hold a blood type (the four blood types are O, A, B, and AB) and an Rh factor (the factors are + and -). Create a default constructor that sets the fields to "0" and "+", and an overloaded constructor that requires values for both fields. Include get and set methods for each field. Save this file as BloodData.java. Create an application names TestBloodData that demonstrates each method works correctly. Save the application as TestBloodData.java

Explanation / Answer

import java.util.Scanner;
public class Patient
{
public static void main(String[] args)
{
    String patient_ID;
    int patient_Age;
    String patient_Rh;
    String patient_Blood;
    Scanner input = new Scanner(System.in);
    System.out.print("what is the patients ID?");
    patient_ID=input.nextLine();
    Scanner input = new Scanner(System.in);
    System.out.print("what is the patients age?");
    patient_Age=input.nextInt();
    input.nextLine();
    Scanner input = new Scanner(System.in);
    System.out.print("what is the patients RH?");
    patient_Rh=input.nextLine();
    Scanner input = new Scanner(System.in);
    System.out.print("What is the patients blood type?");
    patient_Blood=input.nextLine();
    Patient newpatient = new Patient(blood,rh,id,age);
    System.out.println("The patients blood type is " +newpatient.getBlood()+". The patients RH is " +newpatient.getRh()+". The patients ID is " +newpatient.getID()+". The patients age is " +newpatient.getAge()+".");
