我已经为此工作了几个小时了，我无法得到它，所以它需要扫描仪输入（int addoneeurocoins=integer.parseint（keyboard.nextline（））；以此类推）用于pursemk1和pursemk2。任何人都知道如何解决它，我绝望了。

import java.util.Scanner;
public class PurseDemoMk2
{    
  public static void main(String[] args)
  {  
    Scanner keyboard = new Scanner(System.in);

    int addOneEuroCoins = Integer.parseInt(keyboard.nextLine());
    int addFiftyCentCoins = Integer.parseInt(keyboard.nextLine());
    int addTenCentCoins = Integer.parseInt(keyboard.nextLine());
    int addOneCentCoins = Integer.parseInt(keyboard.nextLine());

//Purse Object1
    Purse purseMk1 = new Purse();

    purseMk1.addOneEuroCoins();
    System.out.println("Expected: 2.00 euro,  Found: " + String.format("%.2f", purseMk1.getTotal()));
    purseMk1.addFiftyCentCoins();
    System.out.println("Expected: 3.00 euro,  Found: " + String.format("%.2f", purseMk1.getTotal()));
    purseMk1.addTenCentCoins();
    System.out.println("Expected: 3.20 euro,  Found: " + String.format("%.2f", purseMk1.getTotal()));
    purseMk1.addOneCentCoins();
    System.out.println("Expected: 3.22 euro,  Found: " + String.format("%.2f", purseMk1.getTotal()));
    System.out.println(purseMk1);

//Purse Object2    
    Purse purseMk2 = new Purse();

    purseMk2.addOneEuroCoins();
    System.out.println("Expected: 2.00 euro,  Found: " + String.format("%.2f", purseMk2.getTotal()));
    purseMk2.addFiftyCentCoins();
    System.out.println("Expected: 3.00 euro,  Found: " + String.format("%.2f", purseMk2.getTotal()));
    purseMk2.addTenCentCoins();
    System.out.println("Expected: 3.20 euro,  Found: " + String.format("%.2f", purseMk2.getTotal()));
    purseMk2.addOneCentCoins();
    System.out.println("Expected: 3.22 euro,  Found: " + String.format("%.2f", purseMk2.getTotal()));
    System.out.println(purseMk2);
  }
}
