Java, using a variable within classes

Question

How can I use the variable drawMax in a different class?

public int DrawNumberSetting (int drawMax)
{
    System.out.print ("Please enter the maximum number of draws you want to play: ");
    drawMax = scan.nextInt ();
    return drawMax;
}

you mean to say that you want to use a local method variable in another class? Please elaborate. — Faisal Feroz

I just want to use the value the user entered in this method, in another class I have. Is that possible? — Woong-Sup Jung

Just provide drawMax to the other method. Really, can't get the point of your question. — manolowar

Lets say your drawNumberSetting(int drawMax) is declared in class A. That means that any other class that has an instance of class A can call that method and use the returned value.

class B
{
    public void my otherMethod()
    {
        A a = new A();
        int drawMax = a.drawNumberSetting(5);
    }
}

You can turn drawMax into a class level variable and provide a getter\accessor method, like this:

private int drawMax;

public void DrawNumberSetting ()
{
    System.out.print ("Please enter the maximum number of draws you want to play: ");
    drawMax = scan.nextInt ();
}

public int getDrawMax()
{
   return drawMax;
}
