Question

调用AddBirthdayBonus时，余额字段不会更新。任何帮助表示赞赏。

public class class
{
    private float balance;
    private float bob;


    public class(float amount, float bob)
    {
                    balance = amount;
                }
    birthdate = birthday;
    }


    public void AddBirthdayBonus(float todayDate)
    {
      if (todayDate == bob)
      {
     balance += 5;
     }
    }

Answer 1

这样的事情有更多工作机会：

public class MyClass{
    private float balance;
    private float bob;


    public MyClass(float balance, float bob)
    {
                    this.balance = balance;
                    this.bob = bob;
    }


    public void AddBirthdayBonus(float todayDate)
    {
      if (todayDate == bob){
        balance += 5;
      }
     }
}
