Question

sorry, c++ programmer new to java strikes again

i have this code

public class MainView extends View {

    static final int DRAW_LIST_SIZE=100;
    class EventDrawStuff {
        int         a;
        int         b;
        int         c;
    }
    static EventDrawStuff   m_drawList[] = new EventDrawStuff[DRAW_LIST_SIZE];

    class DrumEventDrawStuff {
        int     x;
        int     y;
    } 
    static DrumEventDrawStuff m_eventDrawStuff = new DrumEventDrawStuff();

the declaration of m_drawList seems to work ok, the declaration of m_eventDrawStuff doesn’t compile. what’s the difference, can t just be that m_drawList is an array?
i notice that if i say

static DrumEventDrawStuff[] m_eventDrawStuff = new DrumEventDrawStuff[1];

that is ok but i don’t really want it to be an array of one, since its only a single thing.
i realise the way to fix the original code is to initialize m_eventDrawStuff in the constructor but that seem cumbersome and unnecessary.

perhaps i’ve got the wrong idea altogether, please enlighten me, thanks

You can do it in two way –

1. Make your inner class static

2. Create DrumEventDrawStuff object with the help of MainView object.

   static DrumEventDrawStuff m_eventDrawStuff = new MainView().new DrumEventDrawStuff();
