Java “Get” and “Set” Methods

问题:

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.

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;
}

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.

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..

Any ideas where i'm going wrong?

回答1:

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

回答2:

You should use public int collectedDots variable rather than private int collectedDots variable
