Java“获取"和“设置"方法 [英] Java "Get" and "Set" Methods

问题描述

我有两个类，在类Player中，我有定义为private int collectedDots的变量，我想在另一个类Exit中进行访问.

I have two classes, in class Player i have the variable which is defined as private int collectedDots and I want to access in another class Exit.

我已经在Player类中定义了Get and Set方法，

I have defined the Get and Set method within class Player as such:

public void setCollectedDots(int cd)
{
    collectedDots = cd;
}

public int getCollectedDots()
{
    return collectedDots;
}

但是现在我想从Exit类访问collectedDots字段.当我将这两个方法复制到Exit类时，我一直收到错误cannot find symbol - variable collectedDots.

But now I want to access the collectedDots field from the Exit class. When I copy those two methods into the Exit class I keep getting the error cannot find symbol - variable collectedDots.

据我了解，一旦我设置了get和set方法，便可以从Player类中检索collectedDots变量.

It was my understanding that I would then be able to retrieve the collectedDots variable from the Player class once I set the get and set methods..

有什么想法我要去哪里吗?

Any ideas where i'm going wrong?

推荐答案

我对Java尚不熟悉，但是我想您需要确保已导入要使用的其他类，或者您可以类的实例:

I'm not yet that familiar with java but i guess you need to make sure that you have imported the other class that you would use or you can you an instance of a class:

collectedDots点=新的collectdDots(); int dotsValue = dots.getCollectedDots();

collectedDots dots = new collectedDots(); int dotsValue = dots.getCollectedDots();
