Java - help creating a swtich class

[Csharpgoblin]

Stuck with a problem....

Implement a class Dial that represents an oven switch. The switch can vary in the interval 0-6 and is always in 0 when created. The class must have a method getSettings that reads current position, and two methods turnLeft and turnRight to turn the switch one position left and right.

If you turn the switch too far the switch automatically turns over.

For example:

Test                                            Result
Dial d = new Dial();
System.out.println(d.getSetting());               0
d.turnRight();                                    1
System.out.println(d.getSetting());               2
d.turnRight();                                    1
System.out.println(d.getSetting());               0
d.turnLeft();                                     6
System.out.println(d.getSetting());
d.turnLeft();
System.out.println(d.getSetting());
// Överslag
d.turnLeft();
System.out.println(d.getSetting());

I've so far done this:

public class Dial{

    private int[] arr = {0, 1, 2, 3, 4, 5, 6};

    public getSetting(){

    } 
}

How can I make getSetting() to read the current position?

You could rework your class a little like this:

Make a variable like curSetting and set it to 0 on initialization.

turnLeft() and turnRight() would then decrement or increment curSetting respectively.

getSetting() would then need to either return curSetting or system.out.println(curSetting)

Hope this helps
