Extracted text: 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.
