For this problem, submit an Eclipse project file named CoinStoreYourLastName wit

Question

For this problem, submit an Eclipse project file named CoinStoreYourLastName with your corrected source code for the classes Coin and Main1, and the new class Main2 that you write in Problem 3.

. Find the errors in the Coin and Main1 classes. Submit a list of all the errors and their corrections in a Word text file.

coin class

package coinstore;

Main.Java

For the Coin class, write getter and setter methods for the _price instance variable. Include these methods in your project file.

Write a second class named Main2 with static methods main, getOnSaleCount, getTotalPrice methods:

The main method should:
read comma delimited data lines from the input file coins.txt,

coin.txt

use the String method split to split the line into fields,
use the values of the fields to create a Coin object,
insert the Coin object into an ArrayList collection defined by
     ArrayList<Coin> col = new ArrayList<Coin>( );

The getOnSaleCount method should have this header:

It should use a for loop to look at all of the Coin objects in the collection and count the number of coins that are on sale and return that count. To test this method in Main2, here is how you can set the coins with indices 2 and 4 in the collection to be on sale:

Include a statement or statement that tests the getOnSaleCount method in Main2.
The getTotalPrice method should have this header:

It should use a loop to find the total of the prices of all Coin objects in the ArrayList collection and return that total. Include a statement or statement that tests the getOnSaleCount method in Main2.

Explanation / Answer

//The class represents the object of coin class
//Coin.java
package coinstore;
public class Coin {
   private double _denomination;
   private int _year;
   private char _mintLocation;
   private String _condition;
   private double _price;
   private boolean _onSale;

   // Constructor
   public Coin(double theDenom, int theYear, char theMint,
           String theCondition, double thePrice) {

       // Face value of the coin, for example
       // Quarter = 0.25, Dime = 0.10.
       _denomination = theDenom;

       // Year that the coin was minted.
       _year = theYear;

       // Location coin was minted. Values are
       // 'D'=Denver, 'S'=San Francisco,
       _mintLocation = theMint;

       _price = thePrice;

       // Condition of the coin. Values are
       // "XF"=Extra Fine, "VF"=Very Fine, "F"=Fine,
       // "VG"=Very Good, "G"=Good, "P"=Poor.
       _condition = theCondition;

       // Is the coin on sale?
       _onSale = false;
   }
  
   //Set price
   public void setPrice(double thePrice){
       this._price=thePrice;
   }
  
   //Return price
   public double getPrice(){
       return _price;
   }
  
   //Return boolean value _onSale
   public boolean isOnSale() {
       return _onSale;
   }

   public void setOnSale(boolean onSale) {
       _onSale = onSale;
   }

   @Override
   public String toString( ) {
       return String.format("Denomination: %s/n" +
               "Year: %d Mint Location: %s " +
               "Condition: #s Price: $%6.2f ",
               _denomination, _year, _mintLocation,
               _condition, _price, _onSale);
   }
}
