Question

Create a program that works similarly to SerSongApp with regard to storing and retrieving informaion between program runs and allows users to

a) enter information about golfers (their names and scores), and provides a list of golfers sorted by score. Note that the golfer class is already defined in the support package. You will need to create a SERIALIZABLE VERSION of the golfer class.

GOLFER CLASS

---------------------------------------------------------------------------------------------------

import java.util.Scanner;
import ch06.lists.*;
import support.*; // Golfer

public class GolfApp
{
public static void main(String[] args)
{
Scanner conIn = new Scanner(System.in);

String name; // golfer's name
int score; // golfer's score
  
ListInterface<Golfer> golfers = new ArraySortedList<Golfer>(20);
Golfer golfer;
  
String skip; // Used to skip rest of input line after reading integer

System.out.print("Golfer name (press Enter to end): ");
name = conIn.nextLine();
while (!name.equals(""))
{
System.out.print("Score: ");
score = conIn.nextInt();
skip = conIn.nextLine();
      
golfer = new Golfer(name, score);
golfers.add(golfer);
  
System.out.print("Golfer name (press Enter to end): ");
name = conIn.nextLine();
}
System.out.println();
System.out.println("The final results are");
System.out.println(golfers);
}
}

Explanation / Answer

package com.he.capillary;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Scanner;

class Golfer implements Serializable,Comparable<Golfer> {

   private static final long serialVersionUID = -8123276401636304060L;

   private String name;
   private int score;

   public Golfer(String name2, int score2) {
       this.name = name2;
       this.score = score2;
   }

   public String getName() {
       return name;
   }

   public void setName(String name) {
       this.name = name;
   }

   public int getScore() {
       return score;
   }

   public void setScore(int score) {
       this.score = score;
   }

   @Override
   public String toString() {
       return "Golfer [name=" + name + ", score=" + score + "]";
   }

   @Override
   public int compareTo(Golfer o) {
       return ((Integer)o.getScore()).compareTo(this.getScore());
   }

}

public class GolfApp {
   public static void main(String[] args) {
       Scanner conIn = new Scanner(System.in);

       String name; // golfer's name
       int score; // golfer's score

       List<Golfer> golfers = new ArrayList<Golfer>(20);
       Golfer golfer;
       String skip; // Used to skip rest of input line after reading integer
       System.out.print("Golfer name (press Enter to end): ");
       name = conIn.nextLine();
       while (!name.equals("")) {
           System.out.print("Score: ");
           score = conIn.nextInt();
           skip = conIn.nextLine();

           golfer = new Golfer(name, score);
           golfers.add(golfer);

           System.out.print("Golfer name (press Enter to end): ");
           name = conIn.nextLine();
       }
       System.out.println();
       System.out.println("The final results are");
       Collections.sort(golfers);
       System.out.println(golfers);
   }
}
