import java.util.Scanner; public class RunBloodData { public static void main(String[] args) { Scanner SC = new Scanner(System.in); String b_Type,r_Factor; System.out.print("Enter blood type of patient: "); b_Type=SC.nextLine(); System.out.print("Enter the Rhesus factor (+ or -): "); r_Factor=SC.nextLine(); BloodData b_data; if(b_Type.equals("")&& r_Factor.equals("")) { b_data=new BloodData(); b_data.display(); } else { b_data=new BloodData(b_Type,r_Factor); b_data.display(); } } } class BloodData{ static String bloodType; static String rhFactor; public BloodData() { bloodType="O"; rhFactor="+"; } public BloodData(String b_Type,String r_Factor) { bloodType=b_Type; rhFactor=r_Factor; } public void display(){ System.out.println(bloodType+rhFactor+" is added to the bloodbank.\n"); } }

Hands-on Activity
Blood Bank (Part 2)
Objective:
At the end of the activity, the students should be able to:
• Apply encapsulation to a program.
Software Requirements:
Latest version of NetBeans IDE
Java Development Kit (JDK) 8
Procedure:
1. Modify your program from 04 Hands-on Activity 1 to apply encapsulation. Make bloodType and
rhFactor non-static and private. Remove the constructor with two (2) parameters.
2. The names of the public setter and getter methods should be:
• setBloodType()
• setRhFactor()
• getBloodType()
getRhFactor()
3. Use the setter methods to accept user input.
4. Display the values by calling the getter methods.
Sample Output:
Enter blood type of patient:
Enter the Rhesus factor (+ or -):
O+ is added to the blood bank.
Enter blood type of patient: B
Enter the Rhesus factor (+ or -) :
B- is added to the blood bank.
