Question

Java program

Candidate Class: This class records the information for each candidate that is running for office.

Instance variables:

• first name
• last name
• office they are running for
• the party they represent
• total votes
• a boolean value to record if they won

Methods:

• Custom constructor that accepts first and last name, office and party
• Custom constructor that accepts an instance of another customer
• Getters for all instance variables and setters for total votes and the boolean variable
• toString: This method should output the details of a Candidate. See sample run
• equals: This method should determine if a Candidate passed in is equal to the current candidate. Two candidates are equal if their first and last name are the same and their parties are equal.

Answer 1

class Candidate{
    String firstname=new String();
    String lastname = new String();
    String party=new String();
    String office = new String();
    private int votes=0;
    private boolean win=false;
    //Constructor for get details
    Candidate(String firstname,String lastname,String office,String party){
        this.firstname=firstname;
        this.lastname=lastname;
        this.office=office;
        this.party=party;
    }
    //Constructor of instance
    Candidate(Candidate instance){
        firstname=instance.firstname;
        lastname=instance.lastname;
        office=instance.office;
        party=instance.party;
    }
    //Getters
    String getFirstname(){
        return firstname;
    }
    String getLastname(){
        return lastname;
    }
    String getOffice(){
        return office;
    }
    String getParty(){
        return party;
    }
    int getVotes(){
        return votes;
    }
    boolean getWin(){
        return win;
    }
    //Setters
    public void setVotes(int value){
        votes=value;
    }
    public void setWin(boolean set){
        win=set;
    }
    public String toString(){//toString Method To print Candidate details
        System.out.println("firstname : "+firstname);
        System.out.println("lastname : "+lastname);
        System.out.println("office : "+office);
        System.out.println("party : "+party);
        System.out.println("votes : "+votes);
        System.out.println("win : "+win);
        return null;
    }
  
}

public class MainCandidate{
    static String equals(Candidate c1,Candidate c2){
        if(c1.firstname==c2.firstname && c1.lastname==c2.lastname&& c1.party==c2.party){
            return "Equal";
        }
        return "Not Equal";
    }
  
     public static void main(String []args){
        Candidate Candidate1 = new Candidate("Harry","Potter","Newyork","Republic");
        Candidate Candidate2 = new Candidate("Chris","Jordan","Washinton Dc","Congress");
        Candidate1.setVotes(1000);
        Candidate1.setWin(true);
        Candidate2.setVotes(8999);
        Candidate2.setWin(false);
        System.out.println("Candidate1 firstname : "+Candidate1.getFirstname());
        System.out.println("Candidate1 lastname : "+Candidate1.getLastname());
        System.out.println("Candidate1 office : "+Candidate1.getOffice());
        System.out.println("Candidate1 party : "+Candidate1.getParty());
        System.out.println("Candidate1 votes : "+Candidate1.getVotes());
        System.out.println("Candidate1 win : "+Candidate1.getWin());
        System.out.println("Is Candidate1 equal to Candidate2 : "+equals(Candidate1,Candidate2));
      
        Candidate Candidate3 = new Candidate(Candidate1);//passing Candidate1 instance to Candidate3 which says these are equal values
        System.out.println("Is Candidate1 equal to Candidate3 : "+equals(Candidate1,Candidate3));

     }
}

Output :
