Question

ISu a The paradox d I ata fields (or mputers. Program 3 Assume the existence of a class called Voter which defines two instance variables: Add 10 user to the ArrayList. private String name; rivate char party: 'D'for Democrat or 'R' for Republican Assume that this class implements these two methods: public char getParty() public String tostring) // name and party affiliation Now assume you're in the main method in another class called VoterDriver. Write a Java statement that instantiates an ArrayList of voter objects called voters a) b) Given the constructor interface, public Voter (String name, char party) rite a Java statement that appends (to voters)one Voter, whose name and party are "Leibowitz" and 'D', respectively. Use an anonymous object. Using a standard for loop, write a code fragment that searches the array for Democrats only and prints each Democrat's information on a separate line. e)

// Test.java

import java.util.ArrayList;
import java.util.Scanner;

public class Test {

   public static void main(String[] args) {

       /*
       * Creating an Scanner class object which is used to get the inputs
       * entered by the user
       */
       Scanner sc = new Scanner(System.in);

       ArrayList<Voter> voters = new ArrayList<Voter>();
       Voter v1 = new Voter("Lelbowitz", 'D');
       Voter v2 = new Voter("Billy", 'D');
       Voter v3 = new Voter("Bowles", 'R');
       voters.add(v1);
       voters.add(v2);
       voters.add(v3);
       for (int i = 0; i < voters.size(); i++) {
           if (voters.get(i).getParty() == 'D') {
               System.out.println(voters.get(i));
           }
       }

   }

}

Output:

Voter [name=Lelbowitz, party=D]
Voter [name=Billy, party=D]
