the transfer of the value in a fonction :     public boolean judge(Parcelle p) {
		int xx,yy;
		int co;
           for(int aa=0;aa<9;aa++) {   		
    		for(int bb=0;bb<5;bb++) {
    			if (p.equals(alist.get(aa).get(bb))) {
    				xx=aa;
    				yy=bb;
    				
    				break;
    			}	
    			}
    			}
           co=alist.get(xx+1).get(yy).exist+alist.get(xx-1).get(yy-1).exist+alist.get(xx-1).get(yy).exist+alist.get(xx).get(yy-1).exist+alist.get(xx+1).get(yy+1).exist+alist.get(xx).get(yy+1).exist;
           return co>=2;
	}


alist is a 2-dimension arraylist of Pardelle.
and it alerts that I should initialize the int xx,yy,
but in the loop I've set the value of them.
So I don't know what the problem is.
