    Dodgy class

    I made this class:
    class InOb {
    int i, j;
    boolean pass = true;

    public InOb(int si, int sj) {
    i = si;
    j = sj;
    }
    public void drs(Graphics g, int xplus, int yplus, Container cont) {
    tileIcon.paintIcon(cont, g, xplus, yplus);
    g.drawLine(xplus, yplus, xplus + 50, yplus);
    g.drawLine(xplus, yplus, xplus, yplus + 50);
    g.drawLine(xplus + 50, yplus + 50, xplus + 50, yplus);
    g.drawLine(xplus + 50, yplus + 50, xplus, yplus + 50);
    g.drawString("its" + i + " " + j, xplus + 5, yplus + 30);
    }
    }
    works fine.
    But:
    class Bush extends InOb {

    public void drs(Graphics g, int xplus, int yplus) {
    g.drawLine(xplus, yplus, xplus + 50, yplus);
    g.drawLine(xplus, yplus, xplus, yplus + 50);
    g.drawLine(xplus + 50, yplus + 50, xplus + 50, yplus);
    g.drawLine(xplus + 50, yplus + 50, xplus, yplus + 50);
    g.drawString("its" + i + " " + j, xplus + 5, yplus + 30);
    }
    }
    doesn't work - it says:
    Move/Move.java [39:1] cannot resolve symbol
    symbol : constructor Bush (int,int)
    location: class Move.Bush
    bits [0] [i] = new Bush(0, i);
    ^
    Move/Move.java [143:1] InOb(int,int) in Move.InOb cannot be applied to ()
    class Bush extends InOb {
    ^
    2 errors
    Errors compiling Move.

    please help!

    symbol : constructor Bush (int,int)
    location: class Move.Bush
    bits [0] [i] = new Bush(0, i);

    means that you are trying to create an object of class type "Bush" by passing it 2 int values. This wont work becuase you need to define a constructor for that class that takes 2 int values as parameters.
    In other words, it is looking for a constructor in the class "Bush" that it cant find

    as for the second error i think your going to have to show us more code, it looks like it is trying to apply some sort of calculation or something on an erronous type, maybe just a syntax error somewhere, but im not sure, ill leave it open for someone to have a crack at
    A kram a day keeps the doctor......guessing

    i've solved it now - i had do add the constructor with super(InOb(si, sj));
    which works
