Question

I’m developing an application for Android, and at one point the user chooses a region, after which the contents of all parts of the app is changed. Therefore I need to access an integer throughout the program. I have considered a singleton class, but I can’t figure out how to add just an int, a get() and a set() to it (I want to be able to read everywhere and write in two classes(everywhere is fine)).

Should I simply declare it global?

This is what I’ve got going now, is it ok?

public enum Region {
INSTANCE;
private int rID =0;

public void setRID(int rID) {
    this.rID=rID;

}

public int getRID()
{
    return rID;
}

}

To be accessed with

Region.INSTANCE.setRID(5);

Answer 1

I went with an enum:

public enum Region {
INSTANCE;
private int rID =0;

    public void setRID(int rID)
    {
        this.rID=rID;

    }

    public int getRID()
    {
        return rID;
    }
}

Which I access with

Region.INSTANCE.getRID();
