Question

When I attempt to compile below code I receive the error “Constructor call must be the first statement in a constructor”. Im receiving the error at line this(text, style, font, colour, backgroundBitmap);

Im not within the constructor, im just trying to call it from an initialise method.

public class TimerLabelFieldSingleton extends TimerLabelField{

    private TimerLabelFieldSingleton ref;

    private TimerLabelFieldSingleton(Object text, long style, Font font,
            int colour, Bitmap backgroundBitmap) {
        super(text, style, font, colour, backgroundBitmap);
    }

    private void initialise(Object text, long style, Font font,int colour, Bitmap backgroundBitmap){
        this(text, style, font, colour, backgroundBitmap);
    }

    public TimerLabelFieldSingleton getSingletonObject(Object text, long style, Font font,int colour, Bitmap backgroundBitmap){
        if(ref == null){
            ref = new TimerLabelFieldSingleton(text, style, font,colour, backgroundBitmap);
        }
        return ref;
    }


}

It is not allowed to call the constructor (or super constructor) from anywhere else but in the constructor it self. In other words, you cannot call this() from another method than the constructor.
