JAVA Language   Caesar Shift  Question:  Modify the Caesar class so that it will allow various sized shifts to be used, instead of just a shift of size 3. (Hint: Use an instance variable in the Caesar class to represent the shift, add a constructor to set it, and change the encode method to use it.)         import java.util.*;     public class TestCipher {      public static void main(String[] args)  {        int shift = 7;         Caesar caesar = new Caesar();         String text = "hello world";        String encryptTxt = caesar.encrypt(text);        System.out.println(text + " encrypted with shift " + shift + " is " + encryptTxt);      }    }     abstract class Cipher {      public String encrypt(String s) {        StringBuffer result = new StringBuffer("");         // Use a StringBuffer        StringTokenizer words = new StringTokenizer(s);     // Break s into its words        while (words.hasMoreTokens()) {                     // For each word in s…

Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. our progras from rhFactor non-static and private. Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() 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.

Data structure & Algrothium java program Create the following classes: 1. Name.java object class containing two strings attributes first name and last name (and appropriate constructors, setters/getters)2. NicePerson.java object class containing the name object and an ArrayList of string to store the list gifts ( and appropriate constructors, setters/getters). This class would extend the attached NicePersonInterface.java3. Santa.java object class containing one ArrayList of Names to store the naughty names. Another ArrayList of NicePerson to store the nice names and gifts. Add atleast 4 names in each list and display all information.
